What brand is the Haval H9 engine?
2 Answers
The engine of the Haval H9 is independently developed and produced by Great Wall Motors, belonging to a domestically manufactured engine. The Haval H9 engine model is GW4C20B, with a maximum horsepower of 252, maximum power of 185kW, and maximum torque speed of 355Nm. For daily maintenance of the Haval H9 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 devices 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 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 faults, oil should be changed regularly based on usage conditions, with an appropriate oil level; When oil passes through the fine holes 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, bringing contaminants back to the lubrication parts, accelerating engine wear and internal contamination; Regularly clean the crankcase. During engine operation, high-pressure unburned gas, acids, moisture, sulfur, and nitrogen oxides from the combustion chamber enter the crankcase through the gap between the piston rings and cylinder wall, mixing with metal powder from part wear to form sludge. A small amount remains suspended in the oil, while a large amount precipitates, blocking the filter and oil holes, 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.
Speaking of the Haval H9's engine brand, it's a product independently developed by Great Wall Motors, called the 4C20 series turbocharged engine. For example, the 4C20B gasoline engine has a displacement of 2.0 liters, with a maximum power output of 224 horsepower and a torque of up to 385 Nm. Its technical highlights include direct fuel injection and variable valve timing, making it quite fuel-efficient and delivering strong acceleration. As a mechanical enthusiast with years of car experience, I can say that Great Wall's engine is among the leading ones in domestic SUVs, significantly more efficient than older engines from joint-venture brands like the Toyota Prado, and simpler to maintain—just using standard 5W-30 engine oil is sufficient. However, prolonged high-speed operation might produce some noise, a common issue with turbocharged engines, but regular maintenance can help avoid problems.
