Why Has the Car's Fuel Consumption Suddenly Increased?
1 Answers
Reasons for a sudden increase in car fuel consumption: 1. Use of inappropriate fuel, leading to excessive engine carbon deposits; 2. Damage to the oxygen sensor causing an imbalance in the engine's air-fuel ratio; 3. Prolonged non-replacement of the oil filter, air filter, and fuel filter, resulting in dirt accumulation, impaired functionality, and transmission of incorrect information to the engine control unit, leading to incomplete fuel combustion. Fuel consumption, as defined by national standards, refers to the vehicle's fuel consumption per 100 kilometers obtained in constant-speed fuel consumption tests for certain types of vehicles. It represents the theoretical fuel consumption of a vehicle traveling 100 kilometers on the road at a certain speed.
