ICE Powertrain Research & Development

The internal combustion engine, a fixture of automotive powertrains and power generation since the late 1800s, is quietly undergoing a revolution to meet modern demands for efficiency, productivity and sustainability. Gasoline and diesel engines continue to be dominant platforms, but the automotive, heavy equipment and power generation industries are investing in future-forward hybrid powertrains and new platforms that enable multifuel combustion with a single engine architecture.

Southwest Research Institute (SwRI) offers several engine analysis tools, engineering services and test facilities to support the development and advancement of ICE powertrain and engine combustion systems used in on-highway, off-highway, power generation, and propulsion systems from kilowatt-scale to utility-scale.

Although many transportation end-uses require the energy density of liquid fuel, there’s an industry-wide push toward decarbonization. To balance these seemingly contrary realities, SwRI helps clients with the utilization of low-carbon, alternative fuels such as ethanol, methanol, LPG and even ammonia. Liquid fuels will play a vital role in the transportation sector for the foreseeable future. We develop new and modify and optimize existing ICE powertrain systems to run on low-carbon, alternative fuels.
