提高发动机配气系统寿命的试验

The Technological Experiment to Improve the Durability of Engine Valve Gear

论述了轻质材料的性质及其在发动机上的应用。通过控制制造工艺,改善了TC3进气门、TA8排气门和Si3N4进、排气门的耐磨性,证明采用这些轻质材料,使发动机配气系统的质量下降50%,功率提高10%。

This paper discussed the characteristics of light materials and application in the engine.Through controlling produce technology,TC3 intake valve,TA8 exhaust valve and Si3N4 valves improve their capability of standing wear and tear.Employing the valves of these materials,weight of the valve gear is reduced 50 %,output of engine is improved 10 %.
