SwRI engineers help develop post-refinery diesel treatment that overcomes soot/NOx tradeoff for cleaner burning fuel

Green Car Congress

Southwest Research Institute (SwRI) is helping a client develop a simple post-refinery treatment process that reduces exhaust emissions from diesel engines by overcoming the soot/nitrogen oxides (NO x ) reduction trade-off that has plagued engine researchers for decades.

Hydrogen Opposed Piston Engine Working Group formed

Green Car Congress

OP engines utilize direct injection after ports closure to avoid the risk of fuel short circuiting out the exhaust. Created with the mission to build cleaner, more efficient engines, Achates Power has an experienced staff of engineers and scientists working with leading engine manufacturers to bring the opposed piston engine to market.

Use of Supercritical Diesel Fuel for Improved Efficiency and Reduced Emissions

Green Car Congress

Heat required to bring the fuel to SC states is recovered from the exhaust gas of the engine. To attenuate that risk, the researchers use a diluent such as CO 2 , H 2 O or exhaust gas. George Anitescu from Syracuse presented the work in a poster at the DEER 2009 conference in Dearbon, Michigan. Anitescu et al. DEER 2009).

Report argues advanced HD natural gas vehicles foundational for California to hit air and climate goals; near zero-emission potential

Green Car Congress

To meet federal deadlines for attainment of ozone and fine particulate matter (PM 2.5 ) standards, these regions must expeditiously phase in heavy-duty vehicles that emit at, or below, the equivalent of “zero-emission” battery-electric vehicles when accounting for pollution from base load electricity generation. Advanced After Treatment.

Scuderi Group Unveils Cutaway Model of First Production Prototype of Split Cycle Engine

Green Car Congress

The Scuderi Group unveiled a cutaway model of the first proof-of-concept prototype for its Scuderi Split-Cycle Engine ( earlier post ) at the SAE World Congress in Detroit. The one-liter, naturally-aspirated gasoline prototype is expected to produce up to 80% fewer criteria pollutants than a typical internal combustion engine.
