What engine does Haval use?
2 Answers
Haval adopts the GW4G15 series engine independently developed by Great Wall, which is a domestic engine. All models under the Haval brand use this series of engines. For example: the Haval F7x engine model is GW4C20B, a 1.5T version engine with a maximum power of 124KW, maximum torque of 285Nm, and maximum horsepower of 169. The 2.0T version engine has a maximum power of 165KW, maximum torque of 385Nm, and maximum horsepower of 224. For daily maintenance of Haval engines, 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 according to the additional devices of the intake and exhaust system and usage conditions; for diesel engines, CB--CD grade diesel engine oil should be selected based on mechanical load, with the selection standard not lower than the requirements specified by the manufacturer. 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, which can cause various problems for the engine. To avoid failures, change the oil regularly according to usage conditions and keep the oil volume moderate. When engine 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 the oil cannot pass through the filter element, it may burst the filter element or open the safety valve, allowing oil to pass through the bypass valve and bring dirt back to the lubrication parts, accelerating engine wear and internal contamination. Regularly clean the crankcase. During engine operation, high-pressure unburned gas, acid, 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. When the amount is small, it suspends in the oil; when large, it precipitates from the oil, 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.
As a car enthusiast who frequently researches domestic brands, I've noticed that Haval primarily equips its vehicles with Great Wall's self-developed GW series engines. The mainstay is the 1.5T turbocharged model, such as the third-generation GW4B15, which utilizes 350bar direct injection and CVVL valve lift technology, delivering good fuel consumption control—used in models like the H6 and Shenshou. Off-road models favor the 2.0T engine, like the E20CB twin-scroll turbo engine in the Tank 300, which can unleash 387 N·m of torque at just 1800 rpm, making it particularly suitable for unpaved roads. Recently, they've also introduced high thermal efficiency hybrid-specific engines, such as the one used in the Mocha DHT-PHEV, which can run purely on electricity for about 200 kilometers in urban areas.
