Citroën introduces first members of new 3-cylinder gasoline engine family; 1.0L and 1.2L PureTech reduce fuel consumption about 25%

Green Car Congress

Citroën is introducing the first members of its new PureTech family of three-cylinder gasoline engines on the C3, DS3 and C-Elysée (for international markets) ranges. Depending on the model and the tires fitted, combined cycle fuel consumption for the new family is between 4.3 Citroën developed two different capacity versions: 1.0-liter

Advanced Turbocharged, Direct Injected Gasoline Engines Poised to Take on Diesels in US and in Europe for Reduced Fuel Consumption and Emissions

Green Car Congress

However, prior to the remarks on climate change and the regulatory response, he spent a few minutes discussing the efforts on urban pollution—e.g., What more is need to end urban pollution, something we’ve been spending over 30 years working on? smog and particulates. California’s current LEV II emission standards run through 2010.

Update on DOE Co-Optima project to co-optimize fuels & engines; goal of 30% per vehicle reduction in petroleum

Green Car Congress

In October 2015, the US Department of Energy’s (DOE) launched a broad, joint effort to co-optimize the development of efficient engines and low greenhouse-gas fuels for on-road vehicles with the goal of reducing petroleum consumption by 30% by 2030 beyond what is already targeted. Earlier post.)

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. The extent of fuel-air mixing can be affected by injection system design.
