What engine does the Hongqi H9 use?
2 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 of the engine has a maximum power of 185 kW and a maximum torque of 380 Nm, while the 3.0T version has a maximum power of 208 kW and a maximum torque of 400 Nm. For daily maintenance of the Hongqi H9'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 equipment 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 manufacturer's specified 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, which can cause various problems for the engine. To avoid faults, 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 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 carry contaminants back to the lubrication area, 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 powder from component wear to form sludge. A small amount of sludge remains suspended in the oil, while a large amount 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 the normal operation of the engine but also extends the overall lifespan of the radiator and engine.
I'm particularly fond of studying automotive technical details. The Hongqi H9 offers two engine options: one is a 2.0-liter turbocharged four-cylinder, model CA4GC20TD-31, with a maximum horsepower of 252; the other is a 3.0-liter supercharged V6, model CA6GV30TD-30, with 283 horsepower. Both are paired with a 7-speed dual-clutch transmission, delivering smooth yet powerful driving. In real-world experience, the 3.0T version accelerates quickly on highways, with a slight but well-controlled engine roar. In terms of fuel consumption, it's around 10L/100km in city driving, slightly lower on long trips. This engine is independently developed by Hongqi, featuring direct injection and variable valve timing technology, balancing efficiency and performance, reflecting the high-end progress of Chinese brands. Regular maintenance includes periodic oil changes, especially since the turbo system is prone to carbon buildup, with a recommended check every 50,000 kilometers.
