What engine is equipped in the Ruifeng M3?

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.
