What are the reasons for Weichai's high fuel consumption?
1 Answers
Weichai's high fuel consumption can be attributed to the following reasons: 1. Clean engine carbon deposits: Excessive carbon deposits in the engine are a significant factor, primarily caused by the use of inappropriate fuel. It is recommended to add a certain amount of cleaning agent when refueling. If the effect is not noticeable, it indicates a substantial amount of carbon deposits in the engine. In such cases, the vehicle must be taken to a 4S shop for professional technicians to clean the carbon deposits in the engine. 2. Check the oxygen sensor: As an internal control unit of the car, the oxygen sensor mainly monitors the fuel-air ratio in the engine. Once it is damaged, it will cause an imbalance in the engine's fuel-air ratio, leading to a sudden increase in fuel consumption. After the oxygen sensor is damaged, the vehicle will emit darker exhaust gases from the tailpipe during driving. At this point, the oxygen sensor should be replaced.
