The engine of the Changan Lingxuan is independently produced by Changan Automobile and belongs to a domestically manufactured engine. The 1.5T version of the Changan Lingxuan uses the H15T-AA engine model, with a maximum power of 115kW, maximum torque of 225 Nm, and maximum horsepower of 156. The 1.6L version uses the JL478QEA engine model, with a maximum power of 92kW, maximum torque of 160 Nm, and maximum horsepower of 125. For daily maintenance of the Changan Lingxuan engine, the following methods can be used: Use lubricating oil of 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 system 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 requirements; Regularly change the oil and filter. The quality of any grade of lubricating oil will change during use. After a certain mileage, performance deteriorates, causing various problems for the engine. To avoid malfunctions, change the oil regularly based on usage conditions and keep the oil volume moderate; When oil passes through the fine holes of the filter, solid particles and viscous substances in the oil accumulate in the filter. If the filter is blocked and oil cannot pass through the filter element, the filter element may burst or the safety valve may open, allowing oil to bypass through the bypass valve and bring contaminants back to the lubrication parts, accelerating engine wear and internal pollution; Regularly clean the crankcase. During engine operation, high-pressure unburned gas, 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 powder from part wear to form sludge. A small amount remains suspended in the oil, while a large amount precipitates, blocking filters and oil holes, making engine lubrication difficult and causing wear; Regularly use radiator cleaner to clean the radiator. Removing rust and scale not only ensures normal engine operation but also extends the overall lifespan of the radiator and engine.
