What Causes the Lack of Power and Dull Performance in Refine Business Vehicles?
2 Answers
Jianghuai Refine's lack of power can be attributed to excessive carbon buildup, substandard fuel quality, and other reasons. Below are the specific causes for the dull performance and power deficiency in Refine business vehicles: Carbon Buildup Issues: Carbon deposits here include cylinder carbon buildup, throttle carbon buildup, spark plug carbon buildup, and intake carbon buildup. These areas are directly related to the engine's power output. When excessive carbon accumulates inside the engine, the vehicle's ignition energy decreases, intake efficiency drops, ultimately leading to reduced engine power, resulting in sluggish acceleration and a dull sound. Fuel System: Using incompatible fuel grades (e.g., filling 93-grade fuel with 90-grade) can cause a decline in the vehicle's output power and performance. Alternatively, if the fuel tank vent hole is blocked, or components like the fuel tank switch, fuel filter, or fuel line between the tank and carburetor are partially clogged, the required fuel supply cannot be met, leading to an overly lean air-fuel mixture and weak engine acceleration. Air Intake: Air is one of the engine's power sources. If the air filter is not cleaned promptly after prolonged use and becomes clogged, insufficient air intake will result in an overly rich combustible mixture, reducing engine power. For vehicles equipped with turbochargers, if the turbocharging system malfunctions, the engine will remain sluggish and fail to deliver power even when the throttle is applied. Engine Overheating: Insufficient engine oil, low engine coolant levels, or malfunctioning engine cooling systems can increase the engine's load, leading to poor heat dissipation. Engine overheating impairs lubrication effectiveness, increases mechanical wear, reduces engine power, and results in weak acceleration.
I've been using my Refine business van for cargo transport for seven or eight years, and I've encountered many situations where the power feels sluggish and lacks strength when climbing hills. Once, right after a maintenance service, it still had the same issue, and upon inspection, it turned out the air filter was completely clogged into a black lump! Since then, I make sure to check the air filter every 5,000 kilometers. Once this thing gets blocked, the engine acts like it's suffocating—stepping on the gas pedal all the way does nothing. Also, a clogged catalytic converter is particularly deadly; restricted exhaust flow can directly spike fuel consumption by 20%. Worn-out spark plugs causing unstable ignition can make the car pant like an old ox, so it's best to regularly check combustion chamber carbon buildup with an endoscope. If problems arise right after refueling, you might also need to consider whether low-quality gasoline has clogged the fuel injectors.
