What engine does the Hongqi H9 use?
1 Answers
The Hongqi H9 is equipped with two types of engines: a 2.0-liter turbocharged engine and a 3.0-liter supercharged engine. The engine models are CA4GC20TD-31 and CA6GV30TD-03, respectively. The CA4GC20TD-31 engine has a maximum horsepower of 252 hp, a maximum power output of 185 kW, a maximum power speed of 5500 rpm, and a peak torque of 380 N·m. The CA6GV30TD-03 engine has a maximum horsepower of 283 hp, a maximum power output of 203 kW, a maximum power speed range of 4780-5500 rpm, and a peak torque of 400 N·m. The engines used in the Hongqi H9 are independently developed by FAW, and they are all domestically produced. The engines feature direct fuel injection technology and utilize aluminum alloy cylinder heads and blocks. For daily maintenance of the Hongqi H9's engine, the following methods can be used: Use lubricating oil of the appropriate quality grade. For gasoline engines, select SD-SF grade gasoline engine oil based on the additional equipment of 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 requirements. 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 deteriorates, leading to various engine problems. To avoid malfunctions, change the oil regularly according to usage conditions and maintain an appropriate oil level. When oil passes through the fine pores of the filter, solid particles and viscous substances 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 the filter and carry contaminants back to the lubrication areas, 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. 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 a radiator cleaner to flush the radiator. Removing rust and scale not only ensures the engine operates normally but also extends the overall lifespan of the radiator and engine.
