Abstract
In order to enhance the performance of an automotive engine, many researchers have been carried out. An oil jet cooling a piston is one of important parts for engine performance. Therefore, the efficient cooling system of an oil jet is needed. In this paper, unsteady flow analysis of the oil jet which consists of a check valve and a nozzle has been accomplished. And the reaction between mass flow rate and ball movement was also investigated.
