What is the difference between the fuel consumption published by MIIT and the actual fuel consumption?
1 Answers
Joint-venture models generally have a difference of 1-2 liters between the fuel consumption published by MIIT and the actual average fuel consumption reported by car owners, with some models even achieving a difference of less than 1 liter. However, certain domestic brand models show a gap of more than 2 liters between the MIIT-published fuel consumption and the actual average fuel consumption reported by owners. Below is additional information on vehicle fuel consumption: Reasons for high vehicle fuel consumption: Engine carbon deposits: During long-term operation of a vehicle, the combustion process of gasoline inevitably leads to carbon deposits and sludge. If these deposits and sludge are not cleaned promptly, they can cause an increase in fuel consumption. Another possible cause is faulty spark plugs. The function of spark plugs is to generate a high-voltage electric spark to ignite the air-fuel mixture. If they are damaged, the ignition energy will decrease, leading to uneven combustion of the mixture, which can result in slower acceleration and increased fuel consumption. Solutions for high vehicle fuel consumption: You can clean the engine carbon deposits or replace the spark plugs or clean the carbon deposits from the spark plugs.
