• This paper describes a method for predicting three-dimensional flows in engine cylinders. Predictions were carried out using a finite difference method to solve the governing differential equations for continuity and momentum. A movable grid system was employed and a tridiagonal matrix algorithm was used for pressure correction. To simplify expression of turbulence the concept of effective viscosity was used for convenience. Numerical computations were made for two typical cases, one being a three-dimensional flow during the induction stroke, and the other being a two-dimensional swirling flow in a swirl chamber of an indirect-injection diesel engine. The results have well supported the feasibility of the present computation method in predicting complicated flow phenomena in the engine cylinder and the combustion chamber.
