SwRI’s HEDGE Technology Eliminates Low-Speed Pre-Ignition in Highly Boosted Engines

Green Car Congress

Southwest Research Institute (SwRI) has successfully demonstrated that its HEDGE (High-Efficiency, Dilute Gasoline Engine) technology, using cooled exhaust gas recirculation (EGR) and advanced ignition systems, suppresses low-speed pre-ignition in turbocharged gasoline direct-injection engines. Earlier post.).

Eaton Highlights Range of New Products to Reduce Fuel Consumption and Emissions

Green Car Congress

In the event of slippage it instantaneously engages a hydraulic power supply to transfer extra torque to the wheel with the most traction by modulating the differential from fully open to fully locked, and anywhere in between, depending on driving conditions. —Dave Genise.

Achates Power opposed-piston diesel for TARDEC will demonstrate multi-cylinder configuration

Green Car Congress

Since the pistons cyclically expose or occlude the exhaust and intake ports, there is no valve train. Because the intake and exhaust ports are at the opposite ends of the cylinder, opposed-piston engines have efficient, uniflow scavenging. Scavenging continues until a 230° crank angle, at which time the exhaust ports close.

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

Green Car Congress

Throughout the world, many efforts are being made to improve the thermal efficiency of internal combustion engines. Due to the lower exhaust enthalpy of lower temperature engines using PPCI, it is difficult to produce intake boost with acceptable boost system parasitis. FSN (smoke number). CNL (combustion noise). Combustion stability.

Aeristech develops advanced 12V electric supercharger

Green Car Congress

The eCharger can spin at speeds of up to 80,000 rpm and uses Aeristech’s patented switching technology to reduce the frequency of internal switching events by 60% compared to conventional motors, meaning a significant reduction in heat and improved efficiency on the basis of like-for-like electrical switchgear cost.
