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.

ALABC: 48V mild hybrids can meet emission targets with CO2 reductions of 15-20%

Green Car Congress

The T-Hybrid (based on a Kia Optima) ( earlier post ) and the ADEPT (based on a Ford Focus) ( earlier post ) both utilize an advanced 48V lead-carbon battery system with bolt-on electrical components that allow for significant engine-downsizing without loss in performance. liter engine the performance of a 1.8

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.

HyBoost Project Aiming for 30-40% CO2 Reduction Without Performance Compromise

Green Car Congress

This is to be achieved through the synergistic application of an extremely downsized gasoline engine coupled with electrified boosting and exhaust gas energy recovery; micro-hybrid functionality with stop/start, torque assist and regenerative braking; and a novel energy storage technology.

U Toronto team assess the climate trade-off between reduced CO2 and increased Black Carbon from GDI engines

Green Car Congress

The upside of gasoline direct injection (GDI) engines is widely seen as being improved fuel economy coupled with an increase in specific power (especially with turbocharging), enabling significant downsizing. A significant fraction of the GDI PM 2.5 The extent of fuel-air mixing can be affected by injection system design.

ADEPT project to apply gasoline engine HyBoost system to diesel; 48V architecture; full hybrid fuel economy at much lower cost

Green Car Congress

This combined combined aggressive 50% downsizing of the engine with an electric supercharger for transient low-speed performance and a 12+X volt micro-hybrid stop-start and energy recuperation systems. It is capable of operating in exhaust temperatures up to 850 °C, at speeds up to 60,000 rpm and delivering a peak power of 2 kW (@12V).
