Study investigates impact of operating conditions and load on soot particle number distribution for diesel and biodiesel

Green Car Congress

Among the findings they reported in their paper in the journal Fuel was that under most of the engine operating conditions examined, RME emitted lower soot particle concentration than diesel under both nucleation and accumulation modes. Diesel engines are widely used owing to their high thermal efficiency and low fuel consumption.

SwRI D-EGR gasoline demo vehicle delivers diesel efficiency at lower cost; potential for LEV III/Tier 3 emissions

Green Car Congress

Southwest Research Institute (SwRI) announced preliminary test results of its Dedicated-Exhaust Gas Recirculation (D-EGR) demonstration vehicle ( earlier post ) at the SAE 2014 World Congress in Detroit. D-EGR brake specific fuel consumption (BSFC) at 2000 rpm 2 bar BMEP dropped 14.3% Hydrogen-enriched exhaust is routed to the intake.

Promising Delphi 1st-gen Gasoline Direct Injection Compression Ignition engine meeting ultra fuel efficient program targets

Green Car Congress

Compared to new diesel engines, the Delphi team found that BSFC for GDCI at light loads was comparable or better, and at high loads was about 5% higher. A high octane fuel was injected late on the compression stroke of a boosted diesel engine operating with high EGR. Very low fuel consumption, NO x , and PM emissions were measured.
