The engine of the GM8 Trumpchi is independently developed and produced by Guangzhou Automobile Group Passenger Vehicle Co., Ltd., and is a domestically manufactured engine. The engine model of the GM8 Trumpchi is 4B20M1, with a maximum power of 185kW, maximum horsepower of 252, and maximum torque of 390 Nm. For daily maintenance of the GM8 Trumpchi's engine, the following methods can be used: Use lubricating oil of the appropriate quality grade. For gasoline engines, SD--SF grade gasoline engine oil should be selected based on the additional devices of the intake and exhaust systems and usage conditions; for diesel engines, CB--CD grade diesel engine oil should be selected according to mechanical load, with the selection standard not lower than the manufacturer's specified requirements. Regularly change the engine oil and filter. The quality of any grade of lubricating oil will change during use. After a certain mileage, its performance deteriorates, which can cause various problems for the engine. To avoid malfunctions, the oil should be changed regularly based on usage conditions, and the oil level should be kept moderate. When the oil passes through the fine pores of the filter, solid particles and viscous substances in the oil accumulate in the filter. If the filter becomes clogged and the oil cannot pass through the filter element, it may rupture the filter element or open the safety valve, allowing the oil to bypass through the bypass valve and carry contaminants back to the lubrication areas, accelerating engine wear and increasing internal contamination. Regularly clean the crankcase. During engine operation, high-pressure unburned gases, acids, moisture, sulfur, and nitrogen oxides from the combustion chamber enter the crankcase through the gap between the piston rings and cylinder walls, mixing with metal particles from component wear to form sludge. A small amount of sludge remains suspended in the oil, while a large amount precipitates, clogging filters and oil passages, making engine lubrication difficult and causing wear. Regularly use a radiator cleaner to clean the radiator. Removing rust and scale not only ensures the engine operates normally but also extends the overall lifespan of the radiator and engine.
