What engine is equipped in the Haval H7?
1 Answers
Haval H7's engine is independently developed and produced by China's Great Wall Motors, belonging to a domestically manufactured engine. The engine model of Haval H7 is GW4C20A, with a maximum power of 167kW, maximum horsepower of 227, and maximum torque of 385 N·m. For daily maintenance of the Haval H7 engine, the following methods can be used: Use lubricating oil of appropriate quality grade. For gasoline engines, choose SD--SF grade gasoline engine oil based on the additional devices of the intake and exhaust system and usage conditions; for diesel engines, choose CB--CD grade diesel engine oil based on 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, causing various problems to the engine. To avoid faults, change the oil regularly according to usage conditions and keep the oil volume moderate. When the 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 the oil cannot pass through the filter element, it will either burst the filter element or open the safety valve, passing through the bypass valve and bringing contaminants back to the lubrication parts, accelerating engine wear and 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 powder from part wear to form sludge. A small amount remains suspended in the oil, while a large amount precipitates, clogging 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 normal operation of the engine but also extends the overall lifespan of the radiator and engine.
