What engine is equipped in the Ruifeng M3?

[SebastianLynn]

The engine of the Ruifeng M3 is independently developed by JAC Motors, so it belongs to a domestic engine. The Ruifeng M3-1.5T turbocharged engine model is HFC4GB2-4E, with a maximum horsepower of 150, a maximum power of 110KW, a maximum power speed of 5500rpm, and a maximum torque of 210N.m. The 1.8L naturally aspirated engine model is LJ4A18Q6, with a maximum horsepower of 133, a maximum power of 98KW, a maximum power speed of 5600rpm, and a maximum torque of 182N.m. The engine of the Ruifeng M3 can be maintained daily using the following methods: 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 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 requirements; Regularly change the oil and filter. The quality of any grade of lubricating oil will change during use. After a certain mileage, the performance deteriorates, causing various problems for the engine. To avoid faults, the oil should be changed regularly according to usage conditions, and the oil quantity should be 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, the filter element may burst or the safety valve may open, allowing the oil to pass through the bypass valve and bringing dirt back to the lubrication area, accelerating engine wear and internal pollution; Regularly clean the crankcase. During engine operation, high-pressure unburned gas, acid, water, sulfur, and nitrogen oxides in the combustion chamber enter the crankcase through the gap between the piston ring and the cylinder wall, mixing with metal powder generated by part wear to form sludge. A small amount of sludge suspends 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 life of the radiator and engine.

The engine of the JAC Refine M3 is typically a 1.6-liter gasoline engine independently developed by JAC, featuring VVT technology, with a maximum power output of around 88 kW and torque exceeding 150 Nm. I think this engine offers sufficient power and fuel efficiency for an MPV. It drives smoothly on city roads, responds quickly at startup, and doesn't lag in acceleration on highways, making it especially suitable for daily commutes or family transportation like mine. Maintenance is quite straightforward, with recommended oil changes every 5,000 kilometers and long-lasting spark plugs. Regular inspections can prevent minor issues. Overall, JAC's system is reliable, with good noise control, and generally experiences no major problems over several years of use. It offers high cost-effectiveness and low maintenance costs for those on a budget. If you're looking for more robust power, you might consider the 2.0-liter version, but the 1.6-liter is more practical for everyday use.

The JAC Refine M3 is equipped with a 1.6L naturally aspirated engine from the HFC4GB3 series. Personally, I pay close attention to technical details. It features variable valve timing technology, which optimizes fuel efficiency and emissions, with an actual fuel consumption of around 7 liters per 100 kilometers, making it suitable for regular family use. While researching the engine, I noticed that JAC's design emphasizes durability, with robust materials that resist corrosion and a relatively low failure rate. Common minor issues, such as ignition system faults, can be prevented through regular check-ups. Maintenance is affordable, and even DIY tasks like replacing the air filter are straightforward. Compared to other domestic MPVs, this engine offers better value for money, with stable power output and reduced fatigue during long drives. If you frequently travel long distances, I recommend opting for the higher trim with a turbocharged variant, as it significantly enhances performance.

I'm quite familiar with the 1.6L gasoline engine commonly found on the Refine M3, having worked on it frequently during auto repairs. It's basically an older Jianghuai model with simple and reliable construction. The engine runs quietly, and maintenance mainly focuses on monitoring the oil and cooling system - regular carbon deposit cleaning can extend its lifespan. It provides adequate power for driving, handles urban cargo hauling well, and occasional high RPM on highways isn't problematic. Major issues are rare, though spark plugs tend to wear out but are inexpensive to replace. Overall it's a worry-free, low-maintenance engine suitable for long-term ownership.

I drive the Refine M3 as a family car, and its 1.6-liter engine is quite fuel-efficient with smooth power output, making it great for picking up kids or shopping. In the city, it starts off briskly, and overtaking on the highway isn’t a struggle, with fuel consumption staying around 7 liters, which is cost-effective. Daily use shows good noise control—the engine isn’t loud, making rides comfortable. Maintenance intervals are every 5,000 kilometers, with low costs offering high value for money. If you experience insufficient power, it might be due to a clogged air filter that needs timely replacement. Overall, this engine is a practical choice for those on a budget.
