Delphi Powertrain Study Concludes 3-Cylinder Turbo Gasoline Direct Injection Engine Offers a High-Value NOx and CO2 Solution for Cost-Sensitive Vehicle Segments

Green Car Congress

The Delphi study assessed the technology of downsizing and turbocharging; GDI fueling and its synergies with turbocharging; and an analysis of downsized 3-cylinder versus 4-cylinder engines. Downsizing can be accomplished via reduction in the number of cylinders, and/or a reduction in the displaced volume of each cylinder.

ICCT: decline in diesel sales will have negligible impact on attainment of European CO2 emission standards

Green Car Congress

The combustion of 1 liter of diesel fuel produces approximately 11% more energy than gasoline fuel, but the diesel fuel also releases approximately 11% more CO2 due to its higher carbon content. On top of the higher energy density of diesel fuel, diesel engines historically possessed a number of efficiency advantages over gasoline engines.
