Whose engine does the Hongqi H7 use?
2 Answers
The Hongqi H7 is equipped with an engine independently developed by China FAW Group Corporation. China FAW Group Corporation is currently one of the largest automotive enterprise groups in China and a state-owned mega-sized automobile manufacturer directly under the central government. The engine model used in the Hongqi H7 is CA4GC20TD-11, with a maximum horsepower of 204 HP, maximum power of 150KW at 5500rpm, and peak torque of 260Nm. Here are some daily maintenance methods for the Hongqi H7's engine: Use lubricating oil of appropriate quality grade. For gasoline engines, select SD--SF grade gasoline engine oil based on the additional devices 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 meeting or exceeding 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, performance deteriorates, causing various problems for the engine. To avoid malfunctions, change the oil regularly based on 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 clogged and oil cannot pass through the filter element, it may burst the filter element or open the safety valve, 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. 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 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.
As a mechanic who frequently works on cars, I've handled many engine issues with the Hongqi H7. The engine in this car is the CA4GC series turbocharged engine independently developed by China's FAW Group, such as the 2.0T version outputting 204 horsepower, with technology originating from FAW's own design and manufacturing. Common situations encountered during actual repairs include good cylinder block sealing and high combustion efficiency, but occasionally, owners report slight shaking after startup, which may be caused by minor issues with the high-pressure pump or fuel lines. I recommend choosing the right oil brand and regularly cleaning carbon deposits to avoid this. Overall, the engine's reliability is quite good, especially with smooth power delivery at high speeds, which is even more solid than some joint-venture brands, showcasing the progress of Chinese industry. Maintenance costs are not high, with general replacements like spark plugs costing just a few dozen yuan, though extra attention is needed when matching filter element models. In summary, don't worry about the engine's origin when driving a Hongqi H7—domestic products can be just as durable.
