What engine is used in the Changan Yuexiang?
2 Answers
The engine of the Changan Yuexiang is independently developed by Changan Automobile and belongs to a domestically produced engine. The engine model of the Changan Yuexiang is 472Q16. The 1.4L version engine has a maximum power of 74KW, a maximum torque of 135Nm, and a maximum horsepower of 101. The 1.5L version engine has a maximum power of 78.5KW, a maximum torque of 145Nm, and a maximum horsepower of 107. For daily maintenance of the Changan Yuexiang's 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 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 requirements specified by the manufacturer. 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 will deteriorate, causing various problems for the engine. To avoid malfunctions, the oil should be changed regularly according to usage conditions, and the oil level should be kept moderate. When the 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 the oil cannot pass through the filter element, the filter element may burst or the safety valve may open, allowing the oil to bypass through the bypass valve and bring contaminants back to the lubrication area, accelerating engine wear and 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 powder generated by part wear to form sludge. When the amount is small, it suspends in the oil; when the amount is large, it precipitates from the oil, blocking the filter and oil holes, making engine lubrication difficult and causing wear. Regularly use a radiator cleaner to clean the radiator. Removing rust and scale not only ensures the normal operation of the engine but also extends the overall lifespan of the radiator and engine.
I have personally experienced the Changan Alsvin, which is typically equipped with a Changan self-developed 1.5-liter naturally aspirated four-cylinder gasoline engine, similar to the JL476Q series, with a power output of around 75 kilowatts. The power is sufficient for daily driving, and the fuel consumption is approximately 7-8 liters per 100 kilometers in urban areas, dropping below 6 liters on highways. This engine performs well in terms of smoothness and reliability. I have driven it for several years, and it has minimal vibration at low speeds. However, it's important to change the engine oil and filter regularly to avoid carbon buildup affecting its lifespan. Maintenance costs are moderate, with minor servicing at a 4S dealership costing just a few hundred yuan. It is recommended to use 10W-40 specification lubricating oil.
