Audi Q5L uses the engine model EA211-DSB, with a maximum horsepower of 150 hp, a maximum power of 110 KW, a maximum power speed of 5000 rpm, and a peak torque of 250 Nm. The engine of the Audi Q5L is assembled by FAW-Volkswagen, using German technology, and is a domestically produced engine. For the daily maintenance of the Audi Q5L 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 oil filter. The quality of any grade of lubricating oil will change during use. After a certain mileage, the performance deteriorates, leading to various engine problems. To avoid failures, oil should be changed regularly based on usage conditions, and the oil level should be kept 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 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 bring contaminants back to the lubrication area, accelerating engine wear and increasing internal pollution; 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 remains suspended in the oil, while a large amount precipitates, clogging the filter 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.
