【Abstract】 This paper is concerned with the measuring results of a two-dimensional turbulent flow field inside the chamber and cylinder near the top dead center in a type EQ6100 gasoline engine by LDV. The effects of the chamber geometry, offset valve, squish and engine speed on the mean velocity and turbulence intensity are discussed.更多还原
