Is the Haval engine domestically produced?

[JasonLynn]

Haval engines are made in China. Haval has two main engine production bases, namely the Haval Xushui Factory and the Haval Tianjin Factory. Different Haval models have different engine types. For example, the Haval H9 is equipped with the GW4C20B engine, which delivers a maximum horsepower of 224 HP, a maximum power output of 165 KW at 5500 rpm, and a maximum torque of 385 N.m. The Haval M6, on the other hand, uses the GW4G15F engine, offering a maximum horsepower of 150 HP, a maximum power output of 110 KW at 5600-6000 rpm, and a maximum torque of 210 N.m. For daily maintenance of Haval engines, the following methods can be applied: Use lubricating oil of the appropriate quality grade. For gasoline engines, select SD--SF grade gasoline engine oil based on the additional equipment in the intake and exhaust systems and usage conditions. For diesel engines, choose CB--CD grade diesel engine oil according to the mechanical load, ensuring the standard meets or exceeds the manufacturer's requirements. Regularly change the oil and oil filter. The quality of any lubricating oil will degrade over time. After a certain mileage, the oil's performance deteriorates, leading to various engine issues. To prevent 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 accumulate in the filter. If the filter becomes clogged and oil cannot pass through, it may rupture the filter or open the safety valve, allowing oil to bypass the filter and carry contaminants back to the lubrication points, accelerating engine wear and increasing internal contamination. Periodically 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. These mix with metal particles from component wear to form sludge. In small amounts, sludge remains suspended in the oil, but in large quantities, it precipitates, clogging filters and oil passages, making engine lubrication difficult and causing wear. Regularly use radiator cleaner to flush the radiator. Removing rust and scale deposits not only ensures the engine operates smoothly but also extends the overall lifespan of both the radiator and the engine.
