Why do others only need 6-7 liters of fuel when driving the same car, while you need 7-8 liters or even 9 liters of fuel?
Many car owners attribute the increase in fuel consumption to the natural aging of the vehicle, but in fact, many are caused by overlooked details during the maintenance and use of the vehicle.
In terms of tires
1. The tire pressure is lower than the standard pressure, which increases the rolling resistance of the tire. This will increase the ground contact of the tire and increase friction, not only causing wear on the shoulders of both sides of the tire, but also increasing fuel consumption.
2. Excessive tire wear leads to tire slippage and loss of kinetic energy.
3. Modify wide tires to increase the friction between the tires and the ground.
4. The tire pressure is uneven, and the friction and lateral steering resistance also increase accordingly. There are also potential issues of deviation, difficult steering, and poor braking effect.
5. If the vehicle's four-wheel alignment is not good, it will increase the friction between the tires and the ground, not only causing damage to the tires themselves, but also increasing fuel consumption.
In terms of parts
1. The clutch slips, resulting in a loss of engine speed.
2. The use of spark plugs for too long leads to a decrease in energy generated during ignition, a slowing down of vehicle acceleration, and a significant increase in gasoline consumption.
3. Excessive carbon accumulation in the engine.
4. Excessive or insufficient lubricating oil. Excessive lubricating oil, oil involvement in combustion, incomplete combustion of the mixture, carbon accumulation in spark plugs, mufflers, and other parts, increased fuel consumption, slow growth rate, and decreased power; Too little lubricating oil can cause dry friction between mating parts, causing the engine to overheat, reduce power, and increase fuel consumption.
5. The "three filters" have not been replaced for a long time. During the use of the vehicle, the three filters must be replaced regularly. If they are not replaced for a long time, they will become dirty and greasy, affect use, and transmit incorrect information to the engine control unit, causing insufficient fuel combustion and increased engine carbon deposition.
6. Insufficient cylinder pressure is generally due to poor cylinder tightness, which reduces the energy conversion efficiency of the engine and increases energy consumption.
Driving habits
1. Long periods of idling without stalling or frequent ignition during start-up, as well as frequent rapid acceleration and braking, result in increased fuel consumption, while driving at a constant speed is the most fuel-efficient.
2. Traffic congestion during peak hours is one of the most direct reasons for the soaring fuel consumption of urban vehicles, demonstrating the importance of automatic start stop systems.
3. Opening windows at high speeds not only causes loud noise but also increases fuel consumption.
4. Excessive load increases the weight of the vehicle, such as often placing unnecessary items in the trunk.
5. Prolonged use of air conditioning in the car can also increase fuel consumption. The compressor power of the air conditioner is very high, and it requires a generator to directly provide energy. Of course, the generator is driven by the engine to generate electricity, which increases additional fuel consumption!
6. The warm-up time is too long, and in the morning, the warm-up is not just waiting for the vehicle's speed to drop to normal or the water temperature to rise to normal, which is like being unable to pass through one's wallet.
