Weichai 110 horsepower is a 490 engine, produced by Weifang Diesel Co., Ltd., and is a domestic engine. The model of the Weichai 110 horsepower engine is WP2.3Q110E50, with a maximum torque of 280Nm and a maximum power of 81KW. For the daily maintenance of the Weichai 110 horsepower 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 system and usage conditions; for diesel engines, CB--CD grade diesel engine oil should be selected according to mechanical load, and the selection standard should not be 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 failures, 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 bypass through the bypass valve and still carry dirt back to the lubrication parts, accelerating engine wear and increasing 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 the cylinder wall, mixing with metal powder generated by part wear to form sludge. A small amount of sludge will be suspended in the oil, while a large amount will precipitate out, 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.

Weichai 110 horsepower does not necessarily refer to the 490 engine; it depends on the specific model and year. The 490 is a series designation, typically used in older light trucks or tractors, with a base horsepower ranging from 90 to 100, but there are also versions tuned to 110 horsepower. Horsepower is a power indicator, not a label for the engine itself; different series may output the same horsepower. In Weichai's product line, the WP series, such as the WP3, offers 110 horsepower, while the 490 series can also achieve this level through optimization. If you're buying or repairing a vehicle, check the complete model number on the engine nameplate, like WD615, rather than guessing based on horsepower alone, as this can lead to mismatched parts and affect performance. Choosing the right horsepower for daily driving ensures fuel efficiency and safety. I've handled many cases where confusion over models caused issues, so I recommend verifying official data.

Weichai has a wide range of engine product lines. The 490 represents a traditional series, but it doesn't have a fixed horsepower value. For example, early 490 models might have 90 horsepower, while upgraded versions can reach 110 horsepower. The 110 horsepower is more common in newer series, such as the WP4.1 engine, which also outputs 110 horsepower. Horsepower depends on design and tuning, and the same model can be adjusted to different horsepower levels. I recommend checking the vehicle manual or the official website catalog for specifics, rather than choosing based solely on horsepower, as it might lead to unsatisfactory performance. Weichai is very popular in the truck market, known for its durable machines, but the horsepower level affects cargo hauling efficiency; choosing the wrong one can make uphill driving difficult and increase fuel consumption. Consulting a dealer can help you confirm the model that matches your actual needs, saving you both hassle and money.

I remember my light truck used to have a Weichai 490 engine with 95 horsepower, but I heard it can be modified to 110. The 110 horsepower might not necessarily be from the 490; it could come from the WP3 engine. Horsepower is a measure of power, and engines have model codes for differentiation. Checking the nameplate is the most accurate way—don’t take it lightly. Using the wrong horsepower model can lead to slower acceleration, higher fuel consumption, and affect daily operations.
