HyBoost demonstrator debuts at LCV2011; 50% by swept volume downsizing with low-cost electrification

Green Car Congress

Together the partners have sought to demonstrate an extremely cost-effective, ultra-efficient gasoline engine in a C-segment passenger car delivering the performance of a baseline 2.0-liter naturally aspirated four-cylinder gasoline engine has been replaced with a 1.0L Earlier post.). three-cylinder EcoBoost engine.

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

Green Car Congress

The researchers assessed the gaseous, particulate, and genotoxic pollutants from two current technology gasoline direct injection vehicles when tested in their original configuration and with a catalyzed gasoline particulate filter (GPF). In the study, the team used two MY 2016 passenger cars. —Yang et al.

Concept: Downsized and Supercharged Hybrid Pneumatic Engine for 30%+ Reduction in Fuel Consumption

Green Car Congress

Schematic of downsized and supercharged four-stroke hybrid pneumatic spark injection engine. The reduction in fuel consumption is obtained mainly through enabling the effective use of a heavily downsized engine, rather than from regenerative efficiency. The engine has two intake and two exhaust valves per cylinder. Dönitz et al.

ICCT: decline in diesel sales will have negligible impact on attainment of European CO2 emission standards

Green Car Congress

Other technologies—such as efficiency improvements in gasoline engines as well as the rollout of hybrid electric power trains—offer more compelling and cost-effective pathways to reducing CO 2 emissions from European passenger cars, the ICCT says. For instance, hybrid electric vehicles and diesel cars in the small (e.g.,

Mazdas new SKYACTIV gasoline and diesel engines are steps on the road to its Ideal Engine; focus on compression ratio

Green Car Congress

However, while Mazda plans to offer hybrid vehicles in the medium-term, its engineers are pushing hard to increase the efficiencies of both the gasoline and diesel platforms, moving toward what they call “the ideal Internal Combustion Engine.” Extreme compression ratio rather than downsizing. Although downsizing—i.e.,

Volkswagen Emphasizes Downsizing at 30th Vienna Engine Symposium; Highlights 1.2 TSI and 1.6 TDI

Green Car Congress

Continuing to emphasize a downsizing approach, Volkswagen presented two new engines at the at the 30 th Vienna Engine Symposium (7-8 May): the 1.2-liter liter TSI gasoline engine and the 1.6-liter The potential of internal combustion engines is far from exhausted. It meets the EU 5 exhaust emission standard.

ADEPT project to apply gasoline engine HyBoost system to diesel; 48V architecture; full hybrid fuel economy at much lower cost

Green Car Congress

This combined combined aggressive 50% downsizing of the engine with an electric supercharger for transient low-speed performance and a 12+X volt micro-hybrid stop-start and energy recuperation systems. It is capable of operating in exhaust temperatures up to 850 °C, at speeds up to 60,000 rpm and delivering a peak power of 2 kW (@12V).
