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.

Ricardo to display functional integration prototype of ADEPT 48V “intelligent electrification” diesel

Green Car Congress

The ADEPT project was launched in 2013 to demonstrate the potential for 48V-based intelligent electrification to deliver full hybrid-scale fuel efficiency from a highly cost-effective package. An effective limitation on downsizing, however, is the delivery of acceptable driveability characteristics and launch performance.

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.,
