Air motion in an indirect injection diesel engine

The present investigation of the air motion in the prechamber of an indirect injection diesel engine is in two main parts. In the first part a mathematical model was developed to describe the air motion in the prechamber. In the second part experimental measurements were made of mean air velocities in two different cylindrical prechambers. The prechamber tests were carried out with the engine under motoring conditions. The computations of the mathematical model were compared with the present experimental results and also with previously published data by other authors. A discussion of these comparisons was made.
