Air suction devide for v-type engine

Abstract

Abstract PURPOSE:To obtain a high filling efficiency and make the structure of an air suction device compact by a method wherein the radius of curvature of a cylinder path between a surge tank and a cylinder is increased, a plurality of cylinder paths are made independent from the surge tank and both sides surge tanks are connected mutually through a pressure balance pipe. CONSTITUTION:The titled device is consisting of two sets of surge tanks 16, 16', arranged above banks 5, 5' in the direction of crank shaft and opposing both one ends thereof are closed, and branched paths 17, 17', branched from the surge tank 16, 16' and being extended toward suction ports 9, 9' in the banks 5, 5' located at mutually opposing sides so as to be intersected alternately. The surge tanks 16, 16' of both sides are communicated mutually through a pressure balance pipe 32 so that the internal pressures thereof become equal. According to this method, the high filling efficiency may be obtained and the structure of the device may be made compact.
