What brand is the engine of Dongfeng Fengshen Yixuan?
4 Answers
The engine of Dongfeng Fengshen Yixuan is independently developed by Dongfeng Fengshen and is a domestically produced engine. Dongfeng Fengshen Yixuan uses two types of engines, with model numbers DFMA15T and DFMC10TDS. The engine with model number DFMA15T has a maximum horsepower of 150 HP, a maximum power of 110 kW, a maximum power speed of 5500 rpm, and a peak torque of 230 N·m. The engine with model number DFMC10TDS has a maximum horsepower of 125 HP, a maximum power of 92 kW, a maximum power speed of 5500 rpm, and a peak torque of 196 N·m. For the daily maintenance of Dongfeng Fengshen Yixuan's 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 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, the filter element may burst or the safety valve may open, allowing the oil to pass through the bypass valve and bring dirt back to the lubrication parts, accelerating engine wear and increasing internal pollution. Regularly clean the crankcase. During engine operation, high-pressure unburned gas, acid, moisture, sulfur, and nitrogen oxides in the combustion chamber enter the crankcase through the gap between the piston rings and the cylinder wall, mixing with metal powder produced by part wear to form sludge. A small amount of sludge remains suspended in the oil, while a large amount precipitates from the oil, 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.
I have studied car engines for many years and know that the Dongfeng Aeolus Yixuan is equipped with Dongfeng's self-developed engine brand, such as the C15TDR model 1.5T turbocharged engine. This engine features twin-scroll technology and direct fuel injection design, delivering a maximum power output of approximately 150 horsepower with an official fuel consumption as low as 6L/100km. It provides smooth and powerful acceleration during high-speed driving. In urban conditions, it integrates an automatic start-stop function to reduce idle fuel consumption, making it well-suited for Chinese road conditions. Dongfeng has leveraged years of technical expertise and incorporated some structural optimizations shared with PSA to enhance reliability, resulting in low overall maintenance costs and readily available parts. When choosing the Yixuan, a test drive focusing on the initial throttle response will reveal the engine's smooth performance. Regular maintenance simply requires basic in-shop checks of engine seals and the cooling system to ensure long-term durability and hassle-free driving.
Having driven the Yixuan for over half a year as my daily commuter, I'm most satisfied with its Dongfeng Fengshen-developed 1.5T engine. In city traffic jams, it responds quickly with smooth acceleration from standstill, maintaining fuel consumption around 7L/100km which handles fuel price fluctuations effortlessly. During highway trips, the well-controlled engine noise ensures a quiet and comfortable cabin, making drives worry-free and safe. During last week's maintenance, the 4S staff explained this is Dongfeng's specially developed engine for Yixuan with localized optimizations for cost-effectiveness and durability. My personal experience confirms high reliability - zero issues in six months, far exceeding expectations. Maintenance is simple with affordable genuine parts, very budget-friendly for salaried workers. Overall, it's been a pleasant experience - this family workhorse delivers full value for money without the hassle of choosing joint-venture engine brands.
As a long-standing domestic automaker, Dongfeng Fengshen has been focusing on self-developed engines since 2009, with the Yixuan's engine being a typical representative branded under Dongfeng itself. Leveraging early joint venture experience with PSA, the C15 series engines feature mature technology with outstanding fuel efficiency and stability, making them well-suited for the local market. Through multiple generations of iterations, such as the full Fengshen engines equipped since the 2020 models, costs have been reduced, benefiting more consumers and continuously improving reputation. This strategy promotes the growth of domestic automobiles by avoiding excessive reliance on foreign technology, which I personally find highly commendable.
