Update on the ACCESS fuel efficient engine project; simulations find up to 48.9% improvement in fuel economy over baseline

Green Car Congress

To achieve the target fuel economy improvement over the baseline V6 configuration, the team used GTDI technology for downsizing in combination with part-load lean homogeneous charge compression ignition (HCCI) operation for further fuel economy gains. Earlier post.). The project team is replacing a 3.6L I4 Ecotec engine. Wheeler, J.,

ACCESS project targeting 30% improvement in fuel economy and SULEV emissions in light-duty gasoline engine; multi-mode SI/HCCI combustion

Green Car Congress

Elements of the multi-mode combustion system include: Spark-ignited (SI) combustion with high compression ratio and high boost assisted by cooled external exhaust gas recirculation (EGR). Two-stage boost—a small supercharger for HCCI, and a regular turbocharger for downsizing. Source: Bosch. Click to enlarge.

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. George Anitescu from Syracuse presented the work in a poster at the DEER 2009 conference in Dearbon, Michigan. To attenuate that risk, the researchers use a diluent such as CO 2 , H 2 O or exhaust gas. At SC conditions, however (T?450
