How to maintain and maintain the car weichai engine
Weichai http:// The car engine is the heart of the car. Maintenance of the car should start with the maintenance of the engine. There are seven main tricks for common car engine maintenance: Run-in 1 This is the basis for extending the service life. Whether it is a new car or an overhauled engine, it must be run-in according to the regulations before it can be put into normal use.  END Oil net, water net, gas net and body net 1 Diesel and gasoline are the main fuels of the engine. If the diesel and gasoline are not pure, the precision will match the wear of the body, and the clearance will increase, causing oil leakage, dripping oil, lower oil supply pressure, larger gap, and even blockage of the oil circuit. Serious failures such as holding shafts and burning tiles. If the air contains a lot of dust, it will accelerate the wear of the liner, piston and piston ring. If the cooling water is not pure, the cooling system will be blocked, the engine will be prevented from dissipating heat, the lubrication conditions will be poor, and the body will be seriously worn. If the external surface of the machine is not clean, the surface will be corroded and the service life will be shortened.  END Oil foot, water foot, air foot 1 If diesel, gasoline and air supply are not timely or interrupted, there will be difficulties in starting, burning, power loss, and engine failure. If the oil supply is insufficient or interrupted, the engine will be poorly lubricated, the body will be worn seriously or even burnt. If the cooling water is insufficient, the machine temperature will be too high, the power will drop, the wear will be intensified, and the service life will be reduced.  END Always check the fastening parts 1 Due to the impact of vibration and uneven load during the use of diesel and gasoline engines, bolts and nuts are easy to loosen. There are also adjustment bolts for each part to be inspected to avoid accidents that damage the body due to looseness.  END Adjust valve clearance and other details 1 The valve clearance, valve timing, fuel supply advance angle, injection pressure and ignition timing of diesel or gasoline engines should be checked and adjusted in time to ensure that the engine is always in good technical state to save fuel and prolong service life.  END Correct choice of maintenance supplies 1 There are many types of engine maintenance products, such as injector cleaning agent, throttle inlet cleaning agent, three-way catalytic cleaning agent, lubricating system cleaning agent, engine protection agent, air conditioning cleaning agent, water tank cleaning agent, gearbox cleaning agent, Power steering cleaning agent, fuel additive, new car wear protection agent, octane improver, etc. There are many well-known brands in the market, but the products are not suitable for long-term use. There are few general-purpose and economical maintenance products. Fuel economy, long-term use of car maintenance.  END Proper use of the engine Lubrication parts such as bushings should be lubricated before driving. After starting, it should be put into operation when the water temperature reaches 40 °C - 50 °C. Prolonged overload or low speed operation is strictly prohibited. Before stopping, the load should be removed first to reduce the speed. After the winter parking, the water temperature should be lowered to 40 °C - 50 °C, and the cooling water should be drained except for the engine that has been injected with antifreeze. Always do a good job of engine maintenance, so that the machine is always in good condition. It is necessary to observe and check frequently, find faults, and eliminate them in time.  |
