Abstract
A number of embodiments of precombustion chamber configurations for two-cycle crankcase compression diesel engines. The precombustion chamber and its communicating throat are oriented so as to maintain a uniform fuel distribution in the precombustion chamber and to provide good flow into the main combustion chamber that will provide a homogeneous mixture without the flow being directed toward the exhaust port at the time the exhaust port is open. A number of embodiments show constructions that permit uniformity of tumble action in the precombustion chamber and a high velocity for the tumble action to improve turbulence and mixing. All of these factors go together to reduce NOx emissions.
