Tenneco’s Powertrain business group is partnering with key academic and industry experts to examine the technical possibilities and commercial feasibility of synthetic fuels as a key technology to help the industry transition to climate-neutral transportation. This collaborative effort is referred to as the NAMOSYN project.

Tenneco, based in Southfield, Michigan, U.S.A., is one of the world’s leading designers, manufacturers and marketers of automotive products for original equipment and aftermarket customers, with full year 2020 revenues of USD15.4 billion and approximately 73,000 employees at more than 270 sites worldwide.

Synthetic fuels for passenger vehicles, commercial trucks or even marine applications can play an important role in achieving a near zero emissions mobility, by using renewable energy sources, such as solar or wind power, to create a closed CO2 cycle when viewed from a holistic “well-to-wheel” perspective, the company said. A climate-neutral alternative to petroleum-based fuels, they also offer the potential for significantly reduced overall emissions.

Synthetically produced, climate-neutral e-fuels can be used in today’s gasoline and diesel engines with only minor modifications for most of e-fuels and in blends with conventional fuels. This makes them particularly suitable for vehicles with traditional internal combustion engines (ICE) as well as alternative powertrains such as hybrids. 

These e-fuels can be made available to consumers by using mostly the existing, well-developed fuel distribution and filling station infrastructure with only minor adjustments, making the technology even more appealing as a near-term, fast-to-market solution.

“It is widely acknowledged that solutions must be found to reduce a vehicle’s carbon footprint. In addition to light vehicles, internal combustion engines are also popular in trucks, marine propulsion, construction equipment and agricultural machinery,” says Dr. Steffen Hoppe, director, Global Technology for piston rings and cylinder liners at Tennecoยดs Powertrain business group in Burscheid, Germany. 

“Regardless of the differing opinions when full electrification will be reached, any technology that we can adopt now that enables a significant reduction in CO2 emissions, or even CO2-neutral operation of the IC engine, will be an essential contributor to the timely achievement of climate targets. We are excited to be an active part in the development of this type of technology.”

To help further the understanding of synthetic fuel technology, Tenneco has joined a consortium of automotive suppliers, vehicle and fuel manufacturers, chemical companies, Fraunhofer institutes and universities as part of the NAMOSYN project (www.namosyn.de), which is supported by the German Federal Ministry of Education and Research. The effort is scheduled to run through March 2022.

Taking advantage of the siteโ€™s 19 fully automated and monitored high-performance test cells, Tennecoยดs Burscheid, Germany team is investigating how innovative piston ring designs in combination with synthetic fuels can be used to develop mobility concepts with lowest emissions, the target being zero emissions impact.

The NAMOSYN project also serves to develop cost-effective and energy efficient manufacturing processes for synthetic fuels and to test them in internal combustion engines. In the diesel sector, this notably concerns the group of oxymethylene ethers (OME); for gasoline engines, the focus is on dimethyl carbonate (DMC) and methyl formate (MeFo). In parallel, a wide range of different material configurations are tested to determine the optimum synthesis and composition over/across the entire process chain.

Initial results of the current research are promising. “By using synthetic fuels in internal combustion engines, we have been able to demonstrate a reduction of 50% or more in all nitrogen oxide, carbon monoxide and particle emissions,” says Bartosch Gadomski, senior test engineer and project manager, NAMOSYN, at Tenneco. “In order to actively support the timely market introduction of synthetic fuels as far as possible, we also test mixtures or blends of conventional fuels and e-fuels under real conditions on our engine test benches.”

In the final step, these test units are installed in test vehicles and examined for driving behavior and emissions. In addition, the compatibility of the e-fuels with the existing infrastructure for fuels, such as tank trucks or filling station systems, is evaluated and solution concepts for new requirements are developed.
