Why does my Chang 'an Yuexiang dashboard show that the fuel consumption exceeds 7?

The engines of yuexiang 20 12 sedan 1.5 MT models are all 1.5L, and the comprehensive fuel consumption of the Ministry of Industry and Information Technology is 6L/ 100km, of which the measured fuel consumption of yuexiang 20 12 luxury model is 6.54l/100.

Regarding your question, at present, I can only list several reasons that may lead to high fuel consumption of vehicles besides driving habits:

First, the air intake, fuel injector and throttle valve are too dirty.

Second, there is something wrong with the oil circuit.

Third, the circuit is faulty.

Fourth, the injection time of the computer is incorrect. You don't know the specific situation until you check it.

The factors affecting automobile fuel consumption are as follows:

1, reducing the self-weight of the vehicle. The weight of the car is directly proportional to the fuel consumption. It is said that every 65,438+00% reduction in vehicle weight will reduce fuel consumption by several percentage points.

2, car modeling. The drag coefficient of the car body is small, and the fuel consumption will decrease obviously. The relationship between the two is also proportional.

3. Improve the thermal efficiency of the engine. At present, the thermal efficiency of general gasoline engines (that is, the ratio of fuel to useful work) has reached more than 30%, while the thermal efficiency of diesel engines has exceeded 40%, which is why diesel engines consume less fuel than gasoline engines.
