What brand is Dongfeng Motors' engine?

The 2009 Yuxuan 2.0L manual luxury model uses the PSA RFN10LH3 Dongfeng engine, with a maximum horsepower of 147 hp, maximum power of 108 KW, maximum power speed of 6000 rpm, and peak torque of 200 N.m. The 2021 Rich 2.4L gasoline four-wheel-drive dream edition long cargo box 2TZD uses the 2TZD engine, with a maximum horsepower of 158 hp, maximum power of 116 KW, maximum power speed of 5000 rpm, and peak torque of 235 N.m. The Dongfeng Fengguang 580 engine is produced in Shiyan, Hubei. The Dongfeng Fengguang 580 engine is built with Fiat technology. For daily maintenance of Dongfeng engines, 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 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, performance deteriorates, leading to various engine problems. To avoid faults, change the oil regularly according to usage conditions and keep the oil volume moderate. When 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 oil cannot pass through the filter element, the filter element may burst or the safety valve may open, allowing oil to pass 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 gas, acid, 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 part wear to form sludge. When the amount is small, it suspends in the oil; when large, it precipitates from the oil, clogging filters 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 engine works properly but also extends the overall lifespan of the radiator and engine.

I've been driving Dongfeng trucks for over a decade and have considerable expertise regarding their engines. Dongfeng operates its own Dongfeng Cummins engine plant specializing in diesel engines, which power most Dongfeng Tianlong trucks on the road - these engines deliver robust power and exceptional durability. In passenger vehicles, the options are more diverse: many Fengshen AX series models are equipped with self-developed Mach engines, now upgraded to 1.5T hybrid versions. Joint venture models offer even more variety: the Dongfeng-Nissan Sylphy comes with HR16 engines, Dongfeng-Peugeot 508 uses 1.8T turbocharged units, while Dongfeng-Honda employs its Earth Dreams technology. When purchasing, examine specific models carefully - domestic series emphasize cost-performance ratio, while joint venture engines generally offer more mature technologies.

Over the years of car repair, I've disassembled many Dongfeng engine compartments. For Dongfeng commercial vehicles, the mainstay is the Cummins series, such as the B6.2 diesel engine. Oil leakage from the valve cover is a common issue, but the torque is truly impressive. Among passenger vehicles, the Dongfeng Fengshen C15TDR engine stands out with its Miller cycle technology, offering excellent fuel consumption control, though the oil pan is prone to seepage. For joint venture models, special attention is needed. The Dongfeng Citroen Tianyi uses the EP6 engine, where the timing chain requires regular checks. Older Dongfeng Fengxing models used the Mitsubishi 4A9 series, which can be a bit troublesome when replacing spark plugs. During maintenance, checking the first three digits of the engine number can help identify the brand and model.

Dongfeng engines are like a big potluck in the automotive world. In the early years, they relied entirely on purchased Mitsubishi engines. Now, commercial vehicles use their own Cummins engines, while passenger vehicles have developed the Mach Power brand, with the 1.5T in the Yixuan racing version capable of squeezing out 300 horsepower. The joint venture sector is even more interesting: Dongfeng Nissan uses the MR20 direct-injection engine, the Venucia D60 is equipped with the HR16, and the Dongfeng Infiniti QX50 directly adopts the VC-Turbo variable compression ratio black technology. In the hybrid field, there's also the Mach MHD hybrid system, with thermal efficiency reaching 45%. As for shortcomings, self-developed models' NVH control can't match joint ventures, but the lifetime warranty policy is quite appealing.

Last week, I accompanied a friend to check out the Dongfeng Haoyi, specifically researching its engine configurations. The car is equipped with a Mach Power 1.5T Mach Dual Hybrid system, with a combined fuel consumption of 4.8L, which is quite impressive. Dongfeng's commercial vehicle lineup is largely dominated by Dongfeng Cummins engines, with their 6-cylinder engines capable of enduring 600,000 kilometers without major overhauls. It's worth mentioning Dongfeng's new energy layout, such as the M917 equipped with four electric motors and the Voyah Dream Home using a 1.5T range extender. Their in-house engine technology is evolving rapidly, with the third-generation Mach engine achieving a thermal efficiency of 41%, even incorporating German craftsmanship in piston coatings. If considering older models, it's advisable to avoid those fitted with the Mitsubishi 4G63 engine, as their fuel consumption is notably higher.

Having been dealing with Dongfeng series in the used car market for five or six years, I've got a thorough understanding of engine know-how. For commercial vehicles, the Dongfeng Cummins ISD series is definitely the right choice, with high value retention and cheap maintenance. For passenger cars, it depends: the Dongfeng Aeolus L7 hybrid uses a Mach hybrid-specific engine with a planetary gear set, which is technologically advanced but depreciates quickly in the second-hand market. Although the HR16DE engine in the classic Sylphy is outdated in technology, it wins with widespread repair points. Special reminder: be cautious when buying discontinued products like the Dongfeng A9, which uses the Peugeot EP6 engine, as timing chain elongation is a common issue. For domestic engines, it's recommended to choose models from the last three years, as the turbo lag in Mach Power has improved significantly.
