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.

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

Green Car Congress

the step-by-step introduction of electrification to SKYACTIV internal combustion engines: stop-start, followed by regenerative braking, followed by electric motor drive technologies. Ultimately, the compression ratio ended up playing a central role among these factors in both gasoline and diesel engines, although in different directions.
