Why is the fuel consumption of Emgrand GL so high?
1 Answers
The reasons for the high fuel consumption of Emgrand GL are as follows: 1. Severe engine carbon deposits: Carbon deposits usually form on the fuel injectors, spark plugs, throttle valve, and combustion chamber. When carbon deposits accumulate to a certain extent, issues such as difficulty in ignition, stalling during neutral coasting or gear shifting, weak acceleration, and unstable idle speed (fluctuating high and low) will occur. 2. Use of low-quality fuel: Since low-quality fuel contains more impurities and cannot be fully burned, most of the gasoline is expelled from the vehicle. At the same time, a layer of white or reddish-brown substance forms on the surface of the oxygen sensor, leading to misjudgment of exhaust oxygen content measurement and transmission of incorrect data, ultimately resulting in poor control of the fuel injection ratio. 3. Excessive vehicle load: There are too many miscellaneous items in the vehicle. Some car owners prefer to place unnecessary items in the vehicle, which increases the weight. Some owners also like to fill up the fuel tank, which also adds to the vehicle's weight. The greater the vehicle load, the greater the pressure of the tires on the ground, and the greater the tire friction. 4. Use of high-power electrical equipment in the vehicle: Especially during idling, due to the low engine speed, the electricity generated by the alternator is insufficient. When high-power electrical equipment (such as air conditioning cooling or high-power audio systems) is used in the vehicle, it increases the burden on the engine and battery. Operating the vehicle under high load conditions will also lead to increased fuel consumption.
