           检查/更换曲轴箱强制通风控制阀　　曲轴箱强制通风控制阀通常安装在阀门罩的下面。闸阀其具体位置可参阅汽车使用手册。　　一般性检查是将曲轴生机盎然强制通风控制阀从阀门罩上取下，截止阀然后摇一摇，如果有喀嗒声，阀门就是正常的。

 　　比较精确的检查步骤如下：

　　1)将转速表接到发动机上。

　　2)当发动机作怠速动转时，将曲轴箱强制通风控制阀从它的底座上取下。

　　3)检查转速表读数。蝶阀用手指按住阀门的入口或者软管的入口，这时应该感觉到有吸力。　　4)再次检查转速表。这时，球阀发动机的转速应该至少下降50r/min。将手指从阀门的端口放开以后，发动机的转速应该恢复到正常值。　　5)如果用手指按住阀门或软管的端口时，止回阀发动机的转速并不改变或者改变的数值低于50r/min，那就是软管被堵塞或者阀门失效。先检查软管，如果软管没有被堵塞，就更换曲轴箱强制通风控制阀。

         Check / replace the crankcase ventilation and control valves Crankcase ventilation and control valves are usually installed in the valve cover the following. Its location can be found in automotive manual. General inspection is mandatory ventilationHydraulic control valves crankshaft lively cast removed from the valve control valve, and then shake, if it clicks, the valve is normal. More precise examination of the Cast Steel following steps: 1) received the engine tachometer. 2) Idle the engine for dynamic change, it will force the crankcase ventilation valve removed from its base. 3) Check the tachometer reading. Water Control valves Hold down the entrance of the valve with your fingers or the hose entrance, then should feel the suction. 4) Check again tachometer. At this time, the engine speed should be at least down 50r/min. The finger port fromOther pumps the valve open, the engine speed should be restored to normal. 5) If the valve or hose with your Forged Steel Valves fingers hold the port, the engine speed does not alter or change the value lower than 50r/min, that the hose is blocked or valve failure. First check the hoses, if the hose is not clogged, the mandatory replacement of the crankcase ventilation valve.
