Increasing the Efficiency of a Two-Stroke Car Diesel Engine
The innovative two-stroke car diesel engine concept from Aumet Oy is based on a very rapid gas exchange through poppet valves in the cylinder head when the piston approaches top dead centre. This rapid gas exchange is achieved by high-pressure scavenging air that is produced externally. From 1990 to 2000, many car manufacturers examined ways of improving the two-stroke car diesel engine.
