China Diesel Engine supplier Cylinder head cover is abbreviated as cylinder head cover. It is a cover on the cylinder head of a diesel engine. It contains valves, rocker assembly push rods and other accessories. It is mostly cast iron or aluminum and stamped from iron plates. The function of the cylinder head cover is: 1. Cover and seal the top of the cylinder head to keep the oil inside while isolating dirt and moisture contaminants from the outside; 2. Isolate the oil from the air; 3. It can be used as a sensor mounting support, including camshaft position and camshaft timing sensors: 4. The fixed support for single-cylinder diesel engine pressure reducing device and oil indicator. The first and most basic function is to cover and seal the cylinder head, keep the oil inside, and at the same time isolate contaminants such as dirt and moisture from the outside. This sounds simple, but it is usually the most difficult aspect to do well. The second function of the cylinder head cover is to isolate the oil from the air. Oil mist is formed during the operation of the engine. The cooler inner surface of the cylinder head cover collects oil mist, condensing the oil and flowing downwards back to the oil sump. The cylinder head cover is also responsible for the ventilation of the crankcase. When the piston moves in the cylinder, pressure builds up inside the engine. If left unattended, this pressure can cause leakage of various seals, resulting in reduced engine efficiency. To avoid this, use a pipe to connect the cylinder head cover and the intake port to burn the ventilation air. The tube can be connected using slotted hose couplings, threaded pipe couplings or quick couplings. The oil baffle or filter in the cylinder head cover is used to prevent the oil from flowing to the intake duct as much as possible. Another function of the cylinder head cover is to act as an oil filler port. This structure can be as simple as a hole into which the oil filler cap is screwed; it can also be a more complicated oil filler pipe. The cylinder head cover can also be used as a sensor mounting support, including camshaft position and camshaft timing sensors. Of course, whether these sensors are included depends on the complexity of the engine. It is easier to find damage to the cylinder cover on the exterior of the diesel engine, such as splitting and deformation are visible to the naked eye. If the above problems are found, they must be replaced in time to prevent foreign matter such as dust or water from entering the oil engine and affecting the normal operation of the diesel engine.China Diesel Engine supplier website:http://www.yey-businesses.com/diesel-engine/
