The engine of the Haval H9 is independently developed by Great Wall and is a domestically produced engine. The engine model used in the Haval H9 is GW4C20B, with a maximum horsepower of 224, a maximum power of 165KW, a maximum power speed of 5500rpm, and a peak torque of 385N.m. For daily maintenance of the Haval H9's engine, the following methods can be used: Use lubricating oil of the 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 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, the performance deteriorates, which can cause various problems for the engine. To avoid faults, the oil should be changed regularly according to usage conditions, and the oil level should be kept moderate. When the 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 will either burst the filter element or open the safety valve, allowing the oil to bypass through the bypass valve and bring contaminants back to the lubrication area, accelerating engine wear and increasing 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 the 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 a 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 the engine.

Speaking of the Haval H9's engine brand, I'm familiar with Great Wall Motors' in-house developed 2.0T turbocharged gasoline engine, model GW4C20B. This beast packs a punch with 223 horsepower output, paired with a ZF 8-speed automatic transmission, making it exceptionally powerful for climbing and off-roading. In terms of driving experience, I find it accelerates quickly, responds agilely, and has significantly improved fuel efficiency compared to older models, with highway fuel consumption controlled at around 12L. Great Wall has made rapid progress in engine technology in recent years, and this model also features dual VVT and direct fuel injection, making the design more compact and reliable. When choosing the Haval H9, I went for it precisely because of this domestically developed engine—great value for money and easy to find repair parts.

I've been driving the Haval H9 for years. This SUV is powered by Great Wall's self-developed 2.0T engine system. It feels very stable to drive, with smooth power delivery and no jerking, performing reliably whether in city driving or on mountain roads. My friend's vehicle has been running for three years with simple and affordable maintenance, covering 50,000 kilometers without any issues. In terms of fuel consumption, it can be reasonably maintained between 11-13L, much more economical than imported vehicles. Domestic engines are becoming increasingly reliable, with convenient parts supply and after-sales response, eliminating the need for frequent visits to 4S shops.

Great Wall Motors has made significant strides in engine technology in recent years, with the Haval H9 being a prime example, equipped with their in-house GW series 2.0T turbocharged engine. This engine delivers ample power and substantial torque, providing a robust and powerful driving experience. Reflecting on the days when Haval relied on externally sourced engines, their current in-house designs are truly impressive—not only fuel-efficient but also well-adapted to various domestic road conditions. In terms of reliability, based on my observations, many owners report virtually no major overhauls, with long maintenance intervals, making it a trustworthy choice.
