EIA: trends in downsized engine design leading to increased demand for higher-octane gasoline

Green Car Congress

Since 2013, the share of premium gasoline in total motor gasoline sales in the US has steadily increased to 11.3% One significant trend is engine downsizing coupled with turbocharging. Turbochargers work by using a turbine driven off the exhaust gas to pressurize the intake air. of new gasoline-fueled LDV sales.

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.,

Pierburg GmbH electric compressor for turbos

Green Car Congress

Pierburg GmbH, part of the KSPG Group, has developed an electric compressor for spontaneously boosting the charge pressure of engines fitted with an exhaust-gas turbocharger. This component allows pressure to be increased regardless of the exhaust-gas energy availability.

Porsche takes top two spots at Le Mans, Audi third

Green Car Congress

(The amount of liquid fuel that may be used in a lap decreases in proportion to the amount of electrical energy a driver is able to employ.). Porsche retained the basic concept of its Class 1 Le Mans Prototype (LMP1) for the second generation: a downsized turbocharged direct injection gasoline engine and two different energy recovery systems.
