1. Pay attention to the use of the running-in period. This is the basis for extending engine life. Whether it is a new OEM quality short engine for BYD or an overhauled engine, it must be run according to the specifications before it can be put into normal operation.
2. Check the fastening parts frequently. The OEM quality short engine is affected by vibration, shock, and uneven load during use, and the bolts and nuts are easy to loosen. The adjusting bolts of each part must be carefully checked to avoid damage to the machine parts due to looseness. Valve clearance, valve timing, and ignition timing should be checked and adjusted in time to ensure that the OEM quality short engine is always in good technical condition and prolong its service life.

3. Keep the oil, water, and body clean. If the fuel is impure, it will wear out the precise matching parts, causing oil leakage, enlarged gaps, and blockage of oil passages. If the cooling water is impure, it will increase the scale of the cooling system and hinder the heat dissipation of the OEM quality short engine for BYD. If the surface of the body is not clean, the body will be corroded and the service life will be shortened.
4. Ensure sufficient oil, water and air. If the supply of gasoline and air is not timely or interrupted, there will be difficulties in starting, poor combustion, power drop, and engine failure. If the oil supply is insufficient or interrupted, the OEM quality short engine will be poorly lubricated and the machine parts will be severely worn. If the cooling water is insufficient, the machine temperature will be too high, the power will drop, the wear will increase, and the service life will be reduced.
5. Observe and check diligently. If any fault is found, it should be eliminated in time, and the maintenance work of the OEM quality short engine for BYD must be done regularly to keep the machine running in a good technical state.
