Large eddy simulation based on the multi-level formulation and quasi-gridless approach is applied for engines. The numbers of grid points are between 1,000,000 and 5,000,000. First, we will compute cyclic variations during six continuous cycles in a model engine. Then, the present numerical code, which can resolve cyclic variations, is applied for analyzing the flow in the first cycle of an actual 4-valve engine with pentroof head.
