GM Developing New Concept for Emission Control for Lean-burn SIDI Engines: Passive Ammonia SCR

Green Car Congress

Engineers at GM’s R&D Center are developing a new low-cost concept for NO x control from lean-burn spark ignition direct injection (SIDI) engines: passive ammonia SCR. Each has drawbacks, noted GM’s Wei Li in a presentation at the recent Department of Energy DEER conference in Dearborn, Michigan. Lean-burn (i.e.,

Germany launches new study of oxymethylene ethers for optimizing clean diesel combustion

Green Car Congress

Further development of diesel and gasoline fuels now offers the chance of preventing the formation of hazardous exhaust gases directly at their origin, i.e. during combustion in the engine. A promising concept for diesel fuels is the use of oxymethylene ethers. The 6 th International Conference on Applied Energy ICAE2014.

UW-Madison engineer collaborating with entrepreneur on 6-cycle, external combustion engine; could be up to 30% more efficient than standard diesel

Green Car Congress

The K6 engine uses six strokes instead of four to reduce the pressure of exhaust gases, which allows it to harvest more energy rather than expelling it with the gas. The K6 engine represents a unique combination of previous concepts. As an external combustion engine, it can be powered by a wide range of liquid and gaseous fuels.
