What is the hfc4de1-1d engine?
2 Answers
hfc4de1-1d engine is a domestically produced engine, with the brand name JAC Ruijiete. It is a joint venture between Cummins and JAC, developed and manufactured by Anhui Jianghuai Automobile Group Co., Ltd. The maximum output power is 112kW, rated speed 3200rpm, maximum horsepower 152hp, maximum torque 355N.m, and maximum torque speed range 1800-2600rpm. Since 2009, JAC Motors has independently developed a total of 10 engines, winning the "China Heart" Top Ten Engines award. For daily maintenance of this engine, 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 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 according to mechanical load, with the selection standard not lower than the manufacturer's specified requirements. 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, causing various problems for the engine. To avoid failures, change the oil regularly based on usage conditions and keep the oil level moderate. When oil passes through the fine pores of the filter, solid particles and viscous substances in the oil accumulate in the filter. If the filter is blocked and oil cannot pass through the filter element, it may burst the filter element or open the safety valve, allowing oil to bypass through the bypass valve and carry contaminants back to the lubrication areas, accelerating engine wear and internal contamination. 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 cylinder walls, mixing with metal powder from component wear to form sludge. In small amounts, it suspends in the oil; in large amounts, it precipitates, clogging filters and oil passages, 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.
I've been repairing cars for over a decade. The HFC4DE1-1D is Jianghuai Automobile's classic 1.5L naturally aspirated gasoline engine, commonly installed in SUVs like the Refine S3 and S5. It delivers around 113 horsepower and 145 N·m of torque. This inline-four engine features DVVT technology to optimize intake and exhaust, with a simple and durable overall structure, though it feels slightly sluggish at low speeds but performs decently at highway speeds. For routine maintenance, I recommend changing the engine oil every 5,000 km and cleaning the air filter to prevent carbon buildup. I've seen many customers encounter overheating issues due to clogged cooling systems. It's cost-effective and suitable for city commuting, though wind noise is noticeable at highway speeds. Regular maintenance can extend its lifespan. Overall, it's a reliable, no-frills engine for family vehicles.
