Delphi to discuss next-generation direct injection at SIA Congress

At the SIA (French Automotive Engineers Society) Congress in Rouen, France this week, Delphi will be presenting information on its latest-generation direct fuel injection and control systems for diesel engines. Delphi produces both electromagnetic servo injectors and the more advanced piezo-electric injectors. For the latest editions of both systems, Delphi has bumped the maximum operating pressures from the 2,000 BAR level that has been used in the last few years up to 2,400 BAR (34,800 psi). T

Lotus: Omnivore engine is 10% more efficient with more to come

Last March at the Geneva Motor Show, Lotus announced its new Omnivore research engine. The Omnivore is a two-stroke direct-injected engine designed to take advantage of the latest in electronic engine management and run on just about any liquid fuel (hence the name). In the time sinc

Lotus' Omnivore engine is already 10% more efficient, with more to come

Last March at the Geneva Motor Show, Lotus announced its new Omnivore research engine. The Omnivore is a two-stroke direct injected engine designed to take advantage of the latest in electronic engine management to allow it to run on j

MIT researchers say HCCI cleaner, more efficient engine

We're not gonna try to explain all the physics involved in this new engine design. That's for all you Autoblog readers with engineering degrees to do in the comments. But, from what we understand, MIT researchers have taken a long hard look at an engine design called homogeneous charge compression ignition (HCCI) and say it could run cleaner and more efficiently than current popular engine designs.
