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.

We see dramatic downsizing and boosting [as] something that’s going to for gasoline engines especially. The basic approach of the downsized 3-cylinder gasoline direct injection (GDI) engine is to reduce engine displacement and decrease engine speed (downsizing and downspeeding) to increase engine load for improved specific fuel consumption.

GMZ Energy, a provider of advanced nano-structured thermoelectric generation technology, was co-founded by MITs Professor Gang Chen and collaborator Zhifeng Ren of the University of Houston. down-speeding, downsized engine, etc.), Ultimately, GMZ will test the final TEG on the dyno, and integrate it into the vehicle.

The more efficient combustion engine technologies, with their enabling of downsizing, come in compatibly with hybridization, with hybridization and electrification playing a larger role over time. The further downsized next-generation technologies can be very synergistic within hybrid applications. Planning background.
