What brand is the engine of the Hongqi H9?
1 Answers
The engine of the Hongqi H9 is independently developed by China FAW and is a domestically produced engine. The engine model of the Hongqi H9 is CA4GC20TD-31. The 2.0T version has a maximum power of 185kW and a maximum torque of 380Nm, while the 3.0T version has a maximum power of 208kW and a maximum torque of 400Nm. For daily maintenance of the Hongqi H9 engine, the following methods can be used: Use lubricating oil of the appropriate quality grade. For gasoline engines, choose 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 based on 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, leading to various engine problems. To avoid malfunctions, change the oil regularly based on usage conditions and maintain an appropriate oil level. When oil passes through the fine holes of the filter, solid particles and viscous substances 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 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. In small amounts, it remains suspended in the oil; in large amounts, it 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 normal engine operation but also extends the overall lifespan of the radiator and engine.
