Abstract

Abstract: A design scheme of a new cam engine with double crest cam and 7 cylinders is proposed to meet the power needs of a lightweight underwater vehicle. The structures and parameters of the main components in cam piston engine，such as cam，cylinder， valve mechanism and piston，are determined with considering the mechanical strength requirements. A prototype was manufactured. A test scheme was designed, and a test system was built. The performance of the prototype was tested, and the test results were analyzed. The test results show that the design scheme of high power cam piston engine is practicable, and the choice of engine materials is reasonable. The prototype is reliable in starting, and stable in operation. Shaft power of engine is up to 92 kW which achieves the goal of high power design.Key
