Three major parts of the engine (How to maintain the three core components of the automobile engine?HS code utilization for tariff refunds) The automobile engine is one of the most core components of the automobile. The three major components of the engine refer to the three core components of the automobile engine: cylinder, crankshaft and connecting rod. Maintaining these three parts is crucial to the life and performance of the engine. So, how should we maintain them? I. Cylinder is one of the most core parts of the engine and one of the most expensive parts of the engine. Inside the cylinder is the combustion chamber, and the engine ignites the fuel and air through the cylinder. It is easy to accumulate carbon inside the cylinder, which will lead to a decline in engine performance and even failure. In order to protect the cylinder, we need to pay attention to the following points: 1. Replace the oil and filter regularly: Replace the oil filter element when replacing the oil, which can prevent the pollution of the exhaust gas and particulate matter inside the cylinder due to poor oil quality.Two. Maintain the quality of oil: Oil plays the role of lubricating, reducing friction and cooling the cylinder. If the oil is seriously aging, contains high moisture or more acidic substances, they will damage the internal parts of the cylinder, resulting in cylinder wear or aging of the gasket. 3. Regular car maintenance: After long-term use, the car will have different faults. Detect problems early and repair them in time, which helps to protect the cylinder and the rest of the internal parts and components. II. The crankshaft is the control system of the engine exhaust and intake valve. The connecting rod on the crankshaft is the main component that converts the energy in the cylinder into the wheel drive. The crankshaft runs at a high speed, so it is necessary to ensure good lubrication and avoid damage caused by defects or aging. How to protect the crankshaft? 1. Change the oil: Timely replacement of the oil can maintain the lubrication effect when the crankshaft is driven and reduce its wear.It is recommended to change the oil according to the guidance of the vehicle manufacturer. Two. Regular engine maintenance: During maintenance, check whether there is oil leakage on the crankshaft cover and seal, and understand whether the butter and lubricant are running at the right temperature. 3. Avoid ultra-high-speed driving: Fast driving will increase the frequency of the crankshaft winding shaft, which may cause the oil to form foam on the crankshaft, thus weakening the lubrication effect of the crankshaft. Of course, it is also necessary to avoid high speed for a long time during normal driving. III. The connecting rod is a component connecting the crankshaft and the piston. It is located in the lower part of the cylinder and needs to withstand high temperature, high pressure and strong inertial force when working. Therefore, maintaining the connecting rod is an important part of maintaining the life of the engine. Next, let's take a look at how to protect the connecting rod: 1. Change the oil regularly: andSimilar to the crankshaft, good oil can reduce the wear of connecting rods and other engine parts and slow down the aging of the engine. Two. Regular engine maintenance: check the connecting rod for wear or other damage, and deal with problems in time. 3. Avoid idling: When the vehicle is in idle, the connecting rod will rotate around the shaft at high speed, which will cause the engine to have too little torque, resulting in damage to its function and service life. Ensuring that the engine is working normally and maintaining the appropriate speed can greatly reduce the wear of the connecting rod. Conclusion: The life and performance of a car engine are inseparable from protecting the cylinder, crankshaft and connecting rod. If the above three parts are properly maintained, the performance of the vehicle will be the best as expected. The protection of these parts also needs to be changed frequently and the car regularly.Maintenance and other precautions to extend the life and operation safety of the car, and ensure the safety of drivers.
