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

Green Car Congress

The current decline is ales of diesel light duty vehicle in Europe does not put EU CO 2 targets out of reach of automakers, according to a new analysis by the International Council on Clean Transportation (ICCT). —The ICCT. For instance, hybrid electric vehicles and diesel cars in the small (e.g., Renault Clio) and lower medium (e.g.,

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. The design brief for the new-generation PureTech engines called for a clean break in powertrain development. PureTech 3-cylinder engine. Click to enlarge. l/100 km (51.1

Study finds highly-turbocharged alcohol-fueled DISI engines could be more efficient than diesels

Green Car Congress

These extreme downsizing indicates the potential of a SI, knock-free engine, operating at the same peak pressure as the diesel engine and higher engine speeds. However this aggressive downsizing may not be practical because other constraints (durability, exhaust temperatures). In this manner a 3.6 —Bromberg and Cohn.

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

First of all, future passenger vehicles have to stay as clean as the best vehicles out there today. Cackette was in effect suggesting that the future tailpipe emissions baseline (LEV III) for light duty passenger vehicles—both diesel and gasoline—was likely to be or to approximate CA SULEV/US Tier 2 Bin 2. smog and particulates.

SwRI to Launch Low-Speed Preignition Prevention Program (P3) Consortium

Green Car Congress

LSPI is considered an impediment to aggressive engine downsizing to reduce carbon dioxide emissions. Low-speed preignition events are random, infrequent occurrences that happen at low speed and high torque, and their causes are not completely understood. Earlier post.). When you ignite the fuel too early, you have very high knock.

SwRI’s HEDGE Technology Eliminates Low-Speed Pre-Ignition in Highly Boosted Engines

Green Car Congress

Southwest Research Institute (SwRI) has successfully demonstrated that its HEDGE (High-Efficiency, Dilute Gasoline Engine) technology, using cooled exhaust gas recirculation (EGR) and advanced ignition systems, suppresses low-speed pre-ignition in turbocharged gasoline direct-injection engines. Earlier post.).
