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.

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.

As one MIT report found, on average, “a fully electric vehicle emits about 25 percent less carbon than a comparable hybrid car.” However, research conducted by the European Energy Agency states that “even when we account for the source of electricity generation, electric cars emit approximately 17-30% less carbon than gasoline or diesel cars.”

On the other hand, drivers of other vehicles waste considerable time making special trips to refuel their internal combustion engine (ICE) vehicles at the liquid fuel station or their battery electric vehicle (BEV) at the rapid recharging station. Diesel fuel is also frequently blended with a small amount of biofuel.
