The Baojun 1.5T engine is indeed a General Motors product, developed and manufactured according to General Motors' powertrain standards. The production line is located at SAIC's Qingdao base. The Baojun 1.5T engine model is LJO, with a maximum power output of 108 kW, maximum torque of 104 N·m, maximum horsepower of 147 Ps, maximum power speed of 5300 rpm, and maximum torque speed range of 2200-3400 rpm. For daily maintenance of the Baojun 1.5T engine, the following methods can be employed: Use lubricating oil of appropriate quality grade. For gasoline engines, select SD--SF grade gasoline engine oil based on the additional devices in the intake and exhaust systems and usage conditions. For diesel engines, choose CB--CD grade diesel engine oil according to mechanical load, with the selection standard not lower than the manufacturer's specified requirements. Regularly change the engine oil and oil filter. The quality of any grade of lubricating oil will deteriorate during use. After a certain mileage, the performance will degrade, leading to various engine issues. To avoid malfunctions, change the oil regularly based on usage conditions and maintain an appropriate oil level. When 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 oil cannot pass through, the filter may burst or the safety valve may open, allowing 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. Small amounts remain suspended in the oil, while larger amounts precipitate, clogging filters and oil passages, making engine lubrication difficult and causing wear. Regularly use radiator cleaner to flush the radiator. Removing rust and scale deposits not only ensures normal engine operation but also extends the overall lifespan of the radiator and engine.
