The Study of Application of New Type Molybdenum - Coated Piston in Diesel Engine
Abstract：The process to coat molybdenum coating with oxygen - ethyne flame on the piston surface is applied to improve its wear durability and the surface hardness. By bench tests, those parameters are measured including oil consumption, power, torque, exhaust temperature when the diesel engine is employed with piston with the molybdenum coating. Compared with the engine e- quipped with the piston without molybdenum coating, the results show that oil consumption decreases about 2.6%, power increases 5kW and maximum torque raises 10N. m but the exhaust temperature decreases about8℃ when the engine uses this new type piston.
