MIT team proposes flex-fuel gasoline-alcohol engine PHEV long-haul trucks

Green Car Congress

In a paper being presented at WCX SAE World Congress Experience in Detroit this week, a team from MIT is proposing the use of a flex-fuel gasoline-alcohol engine approach for a series-hybrid powertrain for long-haul Class 8 trucks. —Daniel Cohn.

RISE Robotics raises $3M in additional funding; electric linear actuation systems

Green Car Congress

The funding round was led by The Engine, the venture firm spun out of MIT that invests in early-stage Tough Tech companies. The majority of heavy machines today rely on hydraulic systems, powered by diesel, to enable motion. Without linear actuators excavators couldn’t dig, garbage trucks couldn’t crush, and forklifts couldn’t lift.

Study finds highly-turbocharged alcohol-fueled DISI engines could be more efficient than diesels

Green Car Congress

Highly turbocharged alcohol-fueled direct-injection spark-ignition (DISI) engines operated at a high compression ratio could be as or more efficient than diesel engines while also providing advantages of lower vehicle cost, lower emissions and higher power, according to a recent modeling study by Leslie Bromberg and Daniel Cohn at MIT.

US DOE awards more than $175M to 40 projects for advanced vehicle research and development

Green Car Congress

This project will optimize fuel-based control of novel combustion strategies in light- and heavy-duty vehicles to enable diesel-like efficiencies with ultra-low engine-out emissions. This project will demonstrate a robust thermoelectric exhaust waste heat recovery system that provides >5% fuel efficiency improvement for a light-duty vehicle.
