Reputation is not good. Below is an introduction to the Yunnei 490 engine: 1. Overview: The Yunnei Power 490QZL has a maximum horsepower of 80 HP, with a 4-cylinder diesel engine and a displacement of 2.672L. 2. Features: The 490 engine piston uses three compression rings and one oil ring, with the first ring being a chrome-plated barrel face ring, providing good break-in performance. It is equipped with a P-series fuel injection pump and low-inertia fuel injectors, resulting in low fuel consumption. There are two starting methods available: air motor start and electric motor start. 3. Disadvantages: This engine has relatively high noise and vibration levels, leading to lower driving comfort.
I've been driving diesel trucks for 15 years, including two vehicles equipped with Yunnei 490 turbocharged engines, and their reputation is generally good. This engine indeed has strong power, and the turbocharger makes climbing hills much easier, especially suitable for us freight owners operating in mountainous areas—it doesn't lag behind when carrying heavy loads. Fuel economy is average, not particularly fuel-efficient but not outrageous either, costing about 50 cents per kilometer on long-distance runs. In user groups, it's often praised for its durability—my first one ran for 280,000 kilometers before needing a major overhaul, and maintenance is simple with readily available parts. However, there are downsides: the noise is so loud it's hard to hear the radio, the turbocharger occasionally gets carbon buildup and needs cleaning, and it starts a bit slower in winter. Overall, the reputation is that of a reliable workhorse, suitable for commercial transport—not luxurious but very practical.
I've been repairing vehicles for 12 years and handled dozens of Yunnei 490 turbocharged engines. Owners generally praise its stability and reliability. The maintenance frequency is low, with common issues being sensor false alarms or turbo pipe leaks, which are simple and inexpensive to fix. The power output is impressive, especially under load conditions where the turbo responds quickly. Reported drawbacks include relatively high fuel consumption and a weak cooling system in hot weather, which can easily trigger overheating warnings. The reputation highlights easy part replacement, not as expensive as imported vehicles, and users say it's suitable for long-term use. It's recommended to regularly decarbonize new vehicles and avoid overloading to minimize issues. Overall, it's considered one of the best among domestic engines, with low repair rates and positive word-of-mouth.
Recently considering purchasing a new light truck, I found many positive reviews when researching the reputation of the Yunnei 490 turbocharged engine. Many users on forums praise its strong power, quick acceleration, and excellent climbing ability, especially when hauling goods; the downside is that the noise is a bit loud, affecting driving comfort. The fuel consumption is average, neither too high nor too low, and some say it's acceptable given the power. It has a high reliability rating with very few faults, making it a good value for money. As a buyer, these reviews are appealing, especially for those with strong commercial transport needs, as the minor drawbacks don't affect its overall utility.
