Now, MIT engineers are proposing using an ammonia-based selective catalytic reduction (SCR) system that could result in an approximately 95% reduction in NO x emissions in exchange for a ~0.5% —Steven Barrett, professor of aeronautics and astronautics at MIT and corresponding author. increase in block fuel burn.

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.

Additionally, suggested one of the speakers, advanced SIDI (spark-ignited, direct-injection) engines can take light-duty market share back from diesels in Europe based on the same trends. Tim Johnson, from Corning, in his review of diesel emission control technology at the conference, started as is his practice by a quick regulatory review.

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.

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. Thermoelectric materials convert temperature differences into electric voltage; a TEG in a vehicle is designed to convert waste heat to power.
