What are the solutions for high fuel consumption in a 10-year-old Lova?
1 Answers
1. Clean engine carbon deposits: Excessive carbon deposits in the engine can lead to high fuel consumption, mainly due to the use of inappropriate fuel. Solution: It is recommended to add a certain amount of cleaning agent when refueling. After cleaning, it is best to drive at high speed for a while, which helps increase exhaust volume and allows stronger airflow to carry out larger carbon deposit particles. 2. Check the oxygen sensor: As an internal control unit of the car, the oxygen sensor mainly monitors the fuel-air ratio of the engine. Once it is damaged, it will cause an imbalance in the fuel-air ratio, and fuel consumption will definitely increase suddenly. Solution: When the oxygen sensor is damaged, the exhaust pipe will emit darker-colored exhaust gas during driving. At this time, the oxygen sensor should be replaced promptly. 3. Regularly replace the three filters: During the use of the vehicle, the oil filter, air filter, and fuel filter must be replaced regularly. If they are not replaced for a long time, they will become dirty and affect performance, sending wrong information to the engine control unit, resulting in incomplete fuel combustion and increased engine carbon deposits. Solution: Regularly perform major and minor maintenance on the car and replace the three filters periodically. 4. Avoid frequent gear shifting while driving: Driving with high throttle and frequent gear shifting can lead to increased fuel consumption. Solution: Avoid frequent gear shifting while driving.
