Which country's engine is used in the Hongqi H9?

[StCharlie]

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 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 engine, the following methods can be used: Use lubricating oil of the 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 the 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, 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 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 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 engine operates normally but also extends the overall lifespan of the radiator and engine.
