Williams F1 Team and Mercedes-Benz enter long-term engine partnership; downsized turbo hybrid Power Units

Green Car Congress

The 2014 regulations require covering a 300 km (186-mile) race distance on a fuel load of just 100 kg. The new ERS will recover energy from both the exhaust turbine and the rear axle, as well as deploying energy back to both. Williams will continue to manufacture its own transmission. liter V8 engines to 1.6

Simulation study suggests ORC waste heat recovery system could deliver potential 7% improvement in fuel consumption in a PHEV on highway

Green Car Congress

Internal combustion engines have been significantly improving in the past decade, after the adoption of technologies such as Gasoline Direct Injection, mild electrification, downsizing and turbocharging. The OSU EcoCAR prototype vehicle features an extended-range electric architecture with a downsized 1.8L —Marcello Canova.

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. the dual injection system design with DI + PFI.

Study finds catalyzed gasoline particulate filters effective at reducing particulate and PAH emissions from GDI engines

Green Car Congress

Bottom: Total particle-phase PAH emissions, expressed in ng/mile, for both test vehicles over the LA92 cycle. Polycyclic aromatic hydrocarbons (PAHs) and nitrated PAHs were quantified in both the vapor and particle phases of the PM, with the GPF-equipped vehicles practically eliminating most of these species in the exhaust.
