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.

New Delphi Technologies 500+ bar GDi system cuts gasoline particulate emissions by up to 50%, reduces fuel consumption

Green Car Congress

Reducing the number of exhaust gas particulates, including those smaller than 23 nm, will help manufacturers meet increasingly stringent future global emissions standards. Reducing engine-out emissions cuts tailpipe emissions in the crucial period before catalyst light-off and reduces the need for costly aftertreatment systems.

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.,
