44th Annual Engine Yearbook: Fueling a New Future

It’s generally acknowledged that the world is in the beginning stages of a massive energy transition from fossil fuels to alternative low- and zero-emissions power sources. And interestingly enough, so are engines, as can be seen in the pages of the 44th annual Engine Yearbook that follow.

Though there are those who believe combustion engine technology is shortly destined for the ash heap of history, the reality is that new fuel system technology and new fuels may keep engines on the job longer – perhaps much longer – than previously imagined.

Several factors are at play, notably economics and time. Literally all things electric, particularly medium- and heavy-duty trucks, off-highway equipment, cost two to three times more than their engine powered equivalents. A refuse truck that normally sells for $300,000 is $600,000 when electrified. Similarly, the diesel-powered version of one global manufacturer’s compact track loader sells for around $85,000 – the all-electric CTL is more than $300,000.

Though at this time there is no real sense about what hydrogen fuel cell technology will cost (and the fact that fuel cell systems also require batteries), it’s fair to conclude that they won’t be much less expensive than purely electric designs. Yes, there are operating and maintenance advantages to electric powertrains, but acquisition costs remain a significant hurdle to adoption, which Jack Roberts discussed in his Street Smarts column elsewhere in this issue.

At the same time, it must be noted that new engine and aftertreatment technologies required by regulations such as the EPA’s Clean Trucks or the California Air Resources Board’s Clean Fleets program will certainly make engine systems much more expensive over time. But it’s unlikely to be anything approaching the orders of magnitude of electric and fuel cell systems.

Another revealing clue as to the short and medium-term prospects for engines can be deduced by adhering to the classic old saying “follow the money.” A number of engine manufacturers – AGCO, Caterpillar, Cummins, Deere, Kubota, Yanmar – have recently launched new engine platforms. Caterpillar was particularly emphatic when launching its new C13D diesel at ConExpo, with one company official proclaiming that Cat is “committed to diesel.”

Similarly, it’s difficult to find an engine company these days that isn’t hard at work in development with hydrogen engines, with some, notably JCB, Cummins and Liebherr, set to bring engines to market as soon as next year. If combustion engines were such a dead end and unlikely to survive beyond the decade, it hardly seems credible that those companies would be spending that kind of money on new product development.

In the same vein, a number of manufacturers are laying out big bucks to improve and modernize their facilities for building engines. One example is Cummins, which is investing more than a billion dollars to upgrade its engine manufacturing sites in Indiana, North Carolina and New York. Through its Accelera by Cummins operation, Cummins has probably been as bullish – and heavily invested – as any company out there when it comes to fostering new and alternative power technologies. Yet it’s also spending a whole lot of cash on developing and manufacturing new engines.

What all this suggests is that the companies that have made their livelihoods for decades by understanding what products their customers need to power vehicles and machines, then delivering them at competitive prices, aren’t quite ready to bury combustion engines just yet.

And why would they when fuel suppliers, including the oil companies that have specialized in refining and delivering liquid fuels for the last 140 years, are beginning to roll out new generations of low-and zero-carbon fuels, such as hydrotreated vegetable oil (HVO), renewable bio-diesel and other nature-based fuel products? As Dr. Ingo Wintruff, managing director of Liebherr’s combustion engine business noted at last year’s Diesel Progress Summit, “The concern is not the combustion engine but the fuel that is burned.”

It’s not a stretch to suggest that those advocating most passionately for the environment might want to support what’s happening with engines and fuels, as it represents the only way to make progress on decarbonization and improve air quality right now, with no need to wait for the installation of electric or hydrogen infrastructures. That will be a massive building program akin to constructing a new interstate highway system and while many billions have been dedicated toward that effort, it will take a lot of time to get it done – more likely a matter of decades than years. To quote Gen. Patton, “a good plan, executed violently now, is better than a perfect plan executed next week.” That logic would seem to apply in this instance.

Bringing that concept closer to home, Cummins Chairman Tom Linebarger noted in an interview with Diesel Progress last year that, “carbon emissions are a little bit like compound interest – the more you put out today, the more decarbonization you have to do in the future, because it sits up there and accumulates and causes challenges today. If we can make impacts today, we’ll have less of a problem in the future.” Engines can and will have that impact, as soon as the next two years.

A final indication of the staying power of combustion engines can be gleaned from the accompanying chart detailing NAFTA engine production, provided by Power Systems Research, the Minnesota-based supplier of global production data and forecasts for the engine and power equipment market. While there are some power bands that have ticked down marginally, the comeback from the COVID year of 2020 has continued in most segments and that doesn’t seem likely to change in the short term.

We remember being advised not too long ago that the Engine Yearbook probably wasn’t going to be around much longer, fading away with the subject matter. However we expect to be chronicling the activities and achievements of internal combustion engines for some time to come. And we hope you’ll come along for the ride.

Engine News

Major launches for AGCO Power over the past year covered the October 2022 introduction of the CORE engine platform and the new 7.5 L turbo CORE75, together with an update for the 84LXTN 8.4 L diesel engine.

The CORE75 is available as both low- and high-speed variants, delivering respectively maximum power of 299250 hp (223 kW) at between 1500 and 1700 rpm and 1450 Nm of torque, and 335 hp (250 kW) at 1850 rpm (same torque output).

The engine is compliant with Tier 4 final/Stage 5 regulations without using an EGR system, while both variants are HVO (hydrotreated vegetable oil) compatible. AGCO states the engines have best-in-class fuel economy of 188 g/KWh.

On the back of a $100 million investment, production of the new CORE75 started in late 2022. Part of that development budget was directed at an all-new machining line, which is scheduled to come online in 2023.

The 84LXTN is an updated version of the existing 84HD engine. Major changes include replacement of the two-stage turbo with a single-stage e-wastegate turbo which is said to reduce complexity and improve reliability. Improvements to the aftertreatment system have supported deletion of the EGR system, which also reduces cooling requirements. Maximum power is 420 hp (313 kW) at 1850 rpm and torque is rated at 1750 Nm at 1500 rpm.

Other recent milestones for AGCO Power include the production of the 100,000th engine at the plant in Changzhou, China (December 2022), and the 30th anniversary of the plant at Mogi das Cruzes in Brazil (March 2023).

The Engine System Manager (ESM2) with AFR2 controls is designed to allow users to see all engine parameters and trend data, as well as view manuals and service bulletins. Additionally, data analytics enhance controls and performance improvements while giving users total control – all without the need for a laptop computer.

The optimized piston reduces emissions of regulated pollutants such as carbon monoxide, volatile organic compounds, and formaldehyde. While the new technology reduces operating costs, support technicians will not need to retrain because of its similarity to existing components.

A two-rig, 8000-hour field validation to study oil consumption and component wear was carried out across six engines, confirming the lab performance of the pistons and cylinder heads, the company said. Waukesha engines running on 100% field gas from producing wells are also providing power for drilling rigs in West Virginia while offsetting 2000 gal. of diesel fuel per day. The switch to mobileFLEX engines is estimated to cut emissions of nitrogen oxides and particulate matter by more than 99%, carbon monoxide by 34%, and carbon dioxide by 7%. Additionally, reducing truck staff has eliminated approximately 200 diesel fuel deliveries, the company said.

INNIO Waukesha and Detechtion Technologies formed a technology collaboration to monitor and optimize gas engines and compressors. The technology partnership will combine INNIO’s Waukesha engine analytics with Detechtion’s compression monitoring and optimization technology into a single solution for both new and existing gas compressor skids. The cloud-based system will help anticipate unexpected service events, improve energy production and reduce plant downtime while fulfilling ESG standards, INNIO Waukesha said.

JCB held the North American unveiling of its hydrogen internal combustion engine at ConExpo-Con/Agg in March this year. The engine is still under development, but the reveal highlighted the clear direction of travel of R&D at JCB.

The proprietary hydrogen combustion process takes place in a new cylinder head using a port fuel injection system. This helps to ensure the gaseous fuel is combined with air in a concentration required to achieve powerful combustion. A variable geometry turbocharger is used to force air into the cylinder head; a spark ignition is used to ignite the mixture.

In October last year, JCB revealed a new hydrogen refueller. This is designed to deliver compressed hydrogen to work sites in much the same way as diesel is now. The refueller delivers hydrogen fuel to onboard tanks in a process intended to be as similar as possible to diesel refuelling.

As of April this year, JCB is continuing to develop of the hydrogen internal combustion engine. While test versions of the engine have been fitted to both backhoe and telehandler machines (the backhoe has received type approval for use on U.K. highways), the company has not yet announced when the engine or the refueller might go into production.

As of August 2022, all Kohler diesel-fueled engines are approved to use hydrotreated vegetable oil (HVO) in the United States, in line with ASTM D975 standard. This confirmation came a few months after European compliance was announced in line with the EN15940 standard.

The use of HVO, whether pure or blended with conventional diesel, does not require any specific engine modifications or upgrades. However, exhaust gas aftertreatment system remains necessary where already provided.

Alongside HVO, Kohler announced at the Bauma 2022 trade show in Munich, Germany, that hydrogen will be included in the company’s strategy as an alternative fuel, as well. Kohler said it expects the technology to be an uphill road but thinks that hydrogen internal combustion engine will be a cost-effective drop-in solution, and potentially adaptable to most applications.

Benefits include a 100% reduction in CO2 emissions and near-zero emissions but with diesel-like performance.

Also considered within the company’s future-looking strategy will be the all-new KSD engine range: a line-up that promises great flexibility of options and quality performance while maintaining a compact design. The engine, already presented as a multi-fuel platform, will be enhanced by the hybrid model.

In September 2022, the KSD engine won the Engine of the Year Under 175 hp award at the Diesel Progress Summit.

Among the judging criteria for the under-175-hp category for new diesel, natural gas or alternative fuel engines, judges considered innovations relating to engine design, emissions, telemetry/connectivity, control technology, packaging, IoT systems, and ease of maintenance and ownership considerations.

The Diesel Progress Summit’s judging panel said the performance and power density of the KSD were very important factors in their decision, but what especially impressed them were the steps Kohler took to ensure the engines could be easily and effectively serviced and maintained in the field.

MAN Engines presented its new V12X engine series at Cannes Yachting Festival 2022. With the newly developed V12 engine for yacht applications, the company said it is now offering its customers an output of 2200 hp (1618 kW) from a 30 L engine.

The MAN V12X-2200 achieves its output of 2200 hp at 2300 rpm from a 138 mm bore and 165 mm stroke.

Compared with the company’s previous most powerful yacht engine – the V12-2000 with 2000 hp (1471 kW) – the displacement of the V12X has been increased by more than 5 L and the maximum torque from 6500 Nm to 7350 Nm.

The V12X is based on a new basic engine, incorporating much from the current V12 engine series, which continues to cover yacht outputs of up to 2000 hp (1471 kW). Findings from the E3872 stationary gas engine developed in parallel complement the development, said the company.

This counterpart for power and heat generation is based on the same basic engine and was presented for the first time back at the end of 2021.

The company has approved all its marine engines from the current range for use with renewable diesel fuel in line with the standard EN15940 in Europe and the U.S. specification ASTM D975.

The company said this will allow customers to replace conventional petroleum-based diesel fuel with “green” or renewable diesel fuel. Renewable diesel fuel is obtained from waste and residues of animal and plant origin, cellulosic biomass such as crop residues, but also hydrotreated vegetable oils (HVO).

On May 10, 2022, MAN Engines put its first two dual fuel hydrogen-powered engines for work boats into operation. These are two 12-cylinder MAN D2862 LE448 engines, each with an output of 749 kW (1019 hp) at 2100 rpm.

The engines are IMO Tier III-certified and equipped with a selective catalytic reduction exhaust gas aftertreatment system. The V12 engines have been prepared for dual fuel operation by MAN Engines and supplemented with a hydrogen injection system by development partner CMB.Tech.

The engine is used on a hydrogen-powered crew transfer vessel (CTV), the Hydrocat 48 from Windcat Workboats. MAN Engines uses a conventional diesel marine engine in which hydrogen is introduced into the charge air via an adapter and is added to the combustion cycle. The combustion process is thereby started according to the diesel principle, said the company, which requires the injection of approximately 5% diesel fuel. The diesel fuel common rail injection parameters have been optimized for dual fuel operation. CO2 tailpipe emissions are reduced through the use of hydrogen by an average of approximately 50%, and even up to 80% as a peak value, reported the company.

A further advantage of using the conventional diesel engine is easy handling when it comes to maintenance and service. Moreover, pure diesel operation can continue without interruption if the hydrogen supply is exhausted.

It introduced the engine, transmission and aftertreatment package to the on-highway market in August 2022, when it was first available in the International LT and RH Series truck models.

Developed from a clean sheet design, the S13 Integrated Powertrain consists of three distinct components – an engine, the International T14 transmission (a 14-speed automated manual transmission) and an aftertreatment system – all developed concurrently to ensure maximized compatibility and integration between systems.

The company said the S13 Integrated Powertrain maximizes performance and capitalizes on efficiency made possible through its modular design which enabled efficient cross-brand development and production throughout Traton Group, while still allowing for regional adaptation and validation of the S13 Integrated Powertrain for the North American market.

For Traton, the Navistar system represented the first group-wide demonstration of a modular solution.

The 13 L S13 diesel engine uses a clean-burn combustion strategy and a reduction of friction and pumping losses. It uses selective catalytic reduction (SCR) technology as the primary emissions reduction technology. Navistar said the absence of an exhaust gas recirculation (EGR) cooler allows for nearly 100% of exhaust to flow to the fixed geometry turbocharger. Additionally, the engine operates on low revolutions and high torque which it said equates to fewer fuel injections and less fuel consumption, delivering up to 515 hp and 1850 lb-ft of torque.

To keep temperatures at an optimal range and extend service intervals, the aftertreatment system includes a dual-stage SCR catalyst system in a one-box design.

The S13 Integrated Powertrain will be manufactured at Navistar’s Huntsville Powertrain Manufacturing Plant in Huntsville, Ala.

Corporate News

In June 2022, Rolls-Royce entered the hydrogen production market by acquiring a 54% majority stake in electrolysis stack specialist Hoeller Electrolyzer, whose technology is expected to form the basis of a new range of mtu electrolyzer products from its Power Systems business unit. Hoeller Electrolyzer, based in Wismar, Germany, is an early-stage technology company that is developing highly efficient polymer electrolyte membrane (PEM) stacks, under the brand name Prometheus, for the cost-effective production of hydrogen.

In March 2023, Rolls-Royce announced it had made significant investments in its manufacturing facilities in Aiken, S.C., and Mankato, Minn., to bring its mtu marine gen-set manufacturing capabilities to the U.S. in support of its contract to supply them for the U.S. Navy’s FFG program. This investment will also support future potential U.S. naval business. The company said the investments included new assembly tooling and material handling equipment, upgraded hoist systems, adapted test cells and building expansion, in addition to the creation of 20 new jobs.

Throughout 2022, the Power Systems division of Rolls-Royce released various mtu engines for use with EN15940 sustainable fuels. In addition to Gas to Liquid (GtL) and Coal to Liquid (CtL), these fuels include sustainable Biomass to Liquid (BtL), Hydrotreated Vegetable Oil (HVO), and Power to Liquid (PtL) fuels such as e-diesel.

The company said the advantages of HVO are clean combustion with a reduction in particulate emissions of up to 80%, nitrogen oxide emissions by an average of 8% and (depending on the manufacturing process and feedstock), CO2 emissions by up to 90% compared to fossil diesel. Testing confirmed that engines perform equally well when using HVO (compared to diesel) in terms of maximum power, load acceptance and fuel consumption. As a drop-in fuel, HVO requires no adaptations to the diesel plant infrastructure, hardware or software for its use.

In May 2022, diesel engines for MTU Series 1600 and 4000 gen-sets were approved for use with sustainable fuels. In addition, rail engines including the Series 1300, 1500 and 1800 were also released – these will be followed shortly by Series 1600 and 4000 engines for rail applications. Further, engines for construction machinery, industrial applications, agriculture and mining for the Series 1000, 1100, 1300, 1500 and 4000 followed in October of 2022. During 2023, marine diesel engines for Series 2000 and 4000 will also be approved for use with sustainable fuels.

In October of 2022, Rolls-Royce and Neste signed a Memorandum of Understanding to build a strategic partnership for the implementation of sustainable fuels for diesel engines. Both companies share a common vision: that sustainable fuels will play a key role in reducing greenhouse gas emissions in off-highway applications. The main components of the agreement are promoting the use of existing internal combustion engines for sustainable fuels, advancing the transition from fossil fuels to sustainable fuels, and HVO knowledge sharing.

Rolls-Royce is also further developing its large marine engines for the Series 1163 and 8000 to comply with the IMO Tier III emissions directive. Starting in 2025, the engines will be available in all cylinder variants in the power range between 4800 and 10,000 KW. This will allow entry into Emission Controlled Areas (ECA), such as the Baltic and North Seas and off the North American coast. Rolls-Royce is also developing the necessary exhaust gas aftertreatment system with selective catalytic reduction (SCR) to adapt it precisely to mtu engines and customer requirements.

In March 2023, Rolls-Royce, Woodward L’Orange and WTZ Roßlau (Wissenschaftlich-Technisches Zentrum Roßlau) announced they have been working on a new joint project called MeOHmare. By the end of 2025, the three partners expect to develop a high-speed internal combustion engine concept for ships that can run on green methanol in a CO2-neutral manner. Rolls-Royce’s business unit Power Systems will develop an engine concept based on the Series 4000 that will be designed for low-emission, CO2-neutral and economical operation of ships with methanol.

Engine News – Power Generation

In July 2022, Rolls-Royce commissioned its first in-house test stand for hydrogen engines at its site in Augsburg, Germany. Over the past year and a half, the company has invested around 10 million euros at Augsburg in test bench modernization, hydrogen infrastructure and other measures as part of its “Net Zero at Power Systems” climate protection program. The company also successfully tested a 12-cylinder gas variant of the Series 4000 L64 engine running on 100% hydrogen fuel. The tests, carried out by the Power Systems business unit, showed very good characteristics in terms of efficiency, performance, emissions and combustion.

Yanmar showed its two newest industrial diesel engines in the US for the first time at ConExpo-Con/Agg. Both the 4TN86CHT and 3TNV80FT engines are designed to meet U.S. EPA/CARB Tier 4 and EU Stage 5 emissions regulations.

The 4TN86CHT is an inline four-cylinder 2.09 L diesel turbocharged and intercooled engine that offers ratings up to 75 hp (55 kW). It offers 14% more power output than previous intercooled turbo models of the same displacement, Yanmar said, and a proprietary DPF system offers a cleaning interval of 6000 hours.

The Yanmar 3TNV80FT is an inline, three-cylinder 1.27 L diesel rated 24.7 hp (18.4 kW). It incorporates Yanmar’s Eco Governor fuel system, which combines a mechanical fuel injection pump with an electronic governor controlled by an ECU.

Yanmar highlighted its newest enclosed power unit at ConExpo. The 4TN107FTT enclosed Powerpack, available in outputs up to 207 hp (155 kW), is designed to deliver the most complete drop-in power unit for a broad range of applications. It is intended to significantly reduce the amount of design and validation work for the OEM, as much of that work, including placement of aftertreatment and controllers, is done by Yanmar.

The Powerpack enclosure typically incorporates three DEF tank bracket kits (3, 5 and 10 gal.) that can be bolted to the side of the enclosure in flexible locations. The length of the heated DEF lines and coolant lines were designed for this flexibility and their performance has been verified via numerous cold box tests, the company said.

The internal design of the enclosure mounts the aftertreatment components separate from the engine to reduce the vibrational response. Units include engine isolation and some aftertreatment weather protection, along with removable side panels for easy maintenance access and a panel mounting location accessible from outside the enclosure.
