Car timing cover action
The main functions of the car timing cover include the following aspects :
Protect the timing system : the timing cover is installed in the location of the timing belt or chain, effectively prevent dust, mud and other external impurities from entering, keep the timing system clean, thereby reducing parts wear, extend the service life .
Sealing and noise reduction : The timing cover forms a closed space to isolate the timing system from the rest of the system to prevent oil, water, mud and other impurities from polluting the timing system, while reducing engine noise .
support engine : the engine is fixed on the car through two support threaded holes, participate in the overall support of the engine .
Structural design and machining accuracy : Although the timing cover is usually not subjected to major forces, its structural design and machining accuracy is critical to the performance and stability of the engine .
Installation and maintenance precautions :
installation method : the traditional installation method is low efficiency and easy to conduct noise, improper installation may lead to timing belt gear jumping when running at high speed, transmission instability, threatening vehicle driving performance .
maintenance : regularly check the sealing and fixing of the timing cover to ensure its normal operation and avoid failure caused by foreign bodies.
Automotive timing cover is an important part of the engine timing system, its main function is to protect the timing belt or timing chain, to ensure that the engine valve and piston can work accurately.
Definition and location
The timing cover is located on the side or top of the engine, close to the camshaft, and its main function is to fix the timing belt or chain to ensure the synchronous operation between the camshaft and the crankshaft, so as to ensure the accurate coordination of the valve opening and closing of the engine and the piston movement.
Material and structure
The timing cover is usually made of aluminum alloy cast, fixed to the side of the engine, and connected to the cylinder block. It is generally not stressed, the upper part is connected with the cylinder head cover, the lower part is connected with the oil pan, and the lower part has a crankshaft oil seal hole. The structure of the timing cover is simple, mainly processing the bonding surface and threaded holes, etc., and will also be attached to the processing of two support threaded holes for fixing the engine support on the vehicle.
Function and effect
protection : The timing cover can effectively prevent dust and external impurities from harming the timing belt or chain, and maintain a good operating environment.
sealing action : It forms a closed space to isolate the timing system from other parts to prevent oil, water, mud and other impurities from polluting the timing system.
noise reduction : reduce the noise of the engine and prevent foreign matter from hitting the timing system.
Installation and maintenance
When installing the timing cover, ensure that the screws are properly installed, and replace the sealing gaskets that may have aged. Regular inspection and maintenance of the status of the timing cover can avoid problems such as oil leakage and ensure the normal operation of the engine.
