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

Green Car Congress

This trend of increasing demand for higher octane gasoline is likely driven by changes in fuel requirements for light-duty vehicles (LDV) in response to increasing fuel economy standards, which will have widespread implications for future gasoline markets, according to EIA analysts.

2014 Sprinter van for US standard with new 2.1L diesel; new driver assistance features

Green Car Congress

The new MY2014 Mercedes-Benz Sprinter van for the US now features a 2.1L, 4-cylinder diesel with a t-speed automatic transmission as standard. Charging takes place at all times via a two-stage exhaust-gas turbocharger system. This downsizing enables lower fuel consumption, accompanied by low emissions and optimum weight.

ECONAMIQ: Flexible over-expansion with cylinder deactivation can reduce ICE fuel consumption by up to 20%

Green Car Congress

Using the pressure from the exhaust gas from the active cylinders, the ‘idle’ cylinders could be expanded to extract more work out of the engine during partial load operation. With this improvement it is shown that the over-expansion cycle has a significant benefit compared to a standard ICE and cylinder deactivation techniques.
