Mazdas new SKYACTIV gasoline and diesel engines are steps on the road to its Ideal Engine; focus on compression ratio

Green Car Congress

However, while Mazda plans to offer hybrid vehicles in the medium-term, its engineers are pushing hard to increase the efficiencies of both the gasoline and diesel platforms, moving toward what they call “the ideal Internal Combustion Engine.” Extreme compression ratio rather than downsizing. Although downsizing—i.e.,

Dearman begins on-vehicle testing of Gen 2 transport refrigeration system powered by liquid air engine; lighter, more efficient

Green Car Congress

The system is powered by an innovative, liquid nitrogen Dearman engine, which replaces the standard diesel engine. Dearman began testing a Generation 1 transport refrigeration system on a truck in early 2015. They are generally diesel-powered and can be up to 29 times more polluting than modern, Euro VI, truck engines.

Bosch leading Direct4Gas consortium to develop direct injection for monovalent natural gas engines

Green Car Congress

The very high octane rating and resulting high resistance to knock is promising for small, supercharged, downsized SI engines. Researchers will also examine mixture formation, ignition, and exhaust-gas treatment and develop specific solutions. The project started in January 2015 and will run until the end of 2017. million (US$4.3

Renault 2010 Environment Workshop, Part 1: Combustion Engine Technology and Product Plans

Green Car Congress

Renault’s ongoing downsizing strategy is aimed at reducing the cubic capacity of its engines in order to bring down fuel consumption and CO 2 emissions, without detracting from performance. dCi (type K9K) diesel is the brand’s best-selling engine with almost 900,000 units manufactured in 2009, in Valladolid (Spain) and Bursa (Turkey).
