What Are the Reasons for High Fuel Consumption in Wuling Vehicles?
2 Answers
There are several reasons for high fuel consumption in Wuling vehicles: 1. Fuel consumption fluctuations due to temperature influence: Low temperatures increase the heat dissipation from the engine. The engine needs to maintain a constant temperature to operate properly, and more heat dissipation requires burning more gasoline to generate heat. 2. Long-term lack of vehicle maintenance: Dirty engine oil and air filters can also lead to increased fuel consumption. Dirty engine oil results in poor lubrication, increasing resistance in the engine's moving parts, which requires more energy to overcome, thereby increasing fuel consumption. 3. Spark plugs need replacement: If ignition occurs after the piston starts moving downward, it leads to partial power loss, with much energy not being used for work. This also causes incomplete combustion, further increasing fuel consumption. 4. Insufficient tire pressure: Insufficient tire pressure increases the contact area between the tires and the ground, raising friction and thus driving resistance, which increases fuel consumption. 5. Incorrect data from certain sensors: If the coolant temperature sensor indicates a lower temperature or the oxygen sensor shows excessive oxygen content, the computer may control to inject more fuel, ultimately leading to incomplete combustion and increased fuel consumption. 6. Excessive carbon buildup in the vehicle: Carbon deposits can accumulate in the throttle body, fuel injectors, intake manifold, and piston tops. Excessive carbon deposits in any of these areas can lead to incomplete combustion, thereby increasing fuel consumption.
Last month I just dealt with the fuel consumption issue of my relative's Wuling Hongguang. Found that novice drivers tend to stomp on the accelerator and brake abruptly - this driving style consumes about 15% more fuel than steady-speed driving. For older Wuling models with 5MT transmissions, frequently revving up to 3000 rpm before shifting makes the fuel tank seem like it's leaking. Also, many owners keep two cases of bottled water plus repair tools in the trunk long-term - carrying an extra 50kg burns half a tank more per month. Saw an extreme case last time where pebbles stuck in rear wheels reduced tire pressure to just 1.8, this hidden resistance caused a 20% fuel consumption spike. Recommend installing a mobile app to monitor real-time fuel consumption - driving problems become immediately apparent.
