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.,

Controlled Power Technologies Packages Its Switched Reluctance Systems in ‘RegEnBoost’ System for Enhanced Support for Downsizing

Green Car Congress

CPT says that the RegEnBoost system enables a typical family-sized car to achieve less than 100 g/km CO 2 with a 1-liter gasoline engine, but when required can offer the same lively performance and in-gear acceleration of a 2-liter naturally aspirated powertrain. The three components of the RegEnBoost system. Click to enlarge.
