Turbulence Generator for Two-Stroke Spark-Assisted Diesel Engines: 4,686,941

A combustion chamber for a spark assisted diesel engine embodying a main combustion chamber and an energy cell. Fuel is injected into the main chamber and into the energy cell and combustion is initiated in the main chamber. The energy cell communicates with the main chamber through a restricted orifice and the increased pressure of the combustion causes auto ignition in the energy cell to generate a high velocity charge out of the energy cell into the main chamber through the orifice for generating turbulence to insure complete combustion.
