降低LJ479Q汽油发动机OCV阀IPTV值的分析

Analysis of Reducing the IPTV of Oil Pressure Control Valve at LJ479Q Engine

OCV是汽油发动机上的一种阀,它控制着发动机进气门的低压机油控制阀,OCV阀故障会导致发动机正时错乱,整车不能启动,怠速不稳,属于严重影响客户使用的问题,因此研究减少OCV阀故障的方法具有很重要的意义。绝大多数的OCV阀故障经分析均因为OCV阀堵塞造成,而研究OCV阀堵塞问题,是一项需要投入大量的人力物力,经过长时间的对比验证,才能确认效果的工作,基于验证要求,以12MIS-IPTV值作为对比依据,回顾过去1年前生产的发动机中存在的售后反馈OCV阀故障数,确认攻关方向的正确性。

OCV is a valve gasoline engine,low pressure oil control valve which controls the engine intake valve,OCV valve failure will lead to engine timing disorder,the vehicle cannot start,idle instability,serious impact oncustomer useing,so reduce the fault of OCV valve is very important. Most of the OCV valve OCV valve faultanalysis because of blockage caused by,and study the OCV valve plug,is a need to invest a lot of manpower andresources,through the contrast verification of long time,in order to confirm the effect of the work,based on thevalidation requirements,set up the 12MIS-IPTV as a comparison basis,review the engine in the customer servicefeedback fault OCV valve number in the past 1 years ago,confirm the correct research direction.
