Many people think that it is normal for a car to consume fuel for a long time, but in fact, there is no necessary relationship between the age of the car and the fuel consumption. The fuel consumption of a car is determined by many factors, but as long as we do it in daily use The maintenance and replacement of some auto parts can effectively prevent these auto parts from “stealing oil”, thereby reducing the fuel consumption of the car.
Tire. Don’t think that tires have nothing to do with fuel consumption. When the tire pressure is too low, the contact area between the tire and the ground will be too large, which will not only increase wear and fuel consumption, but also cause damage to the tire wall and increase the risk of tire blowout when driving at high speed. . Yacco French engine oil recommends that if you find that the sliding distance of the car is significantly reduced during driving, you should check whether the air pressure of the tires meets the air pressure standard. The normal tire pressure is around 2.5bar, which can be reduced by 0.1bar in summer. Also remember to check the degree of wear of the tires. If the tires are severely worn, skidding will occur frequently, and fuel consumption will also increase. Generally, you must replace a new set of tires every 50,000 kilometers.
Spark plug. Problems with spark plugs are basically caused by increased carbon deposits or aging over a long period of time, resulting in a decrease in ignition energy and ignition stability, and an increase in fuel consumption. Generally speaking, the life of resistance spark plugs is 20,000 kilometers, the life of platinum spark plugs is 40,000 kilometers, and the life of iridium spark plugs can reach 60,000-80,000 kilometers. Therefore, the spark plug does not have to be damaged to be replaced. There will be a suggested mileage because although the spark plug is not completely damaged at this time, the ignition efficiency will decrease. In order to ensure normal ignition, it is recommended to replace it.
Three-way catalysis, oxygen sensor. The three-way catalytic converter is an important part of automobile emission and engine combustion, which can reduce the emission of pollutants and meet the emission standards required by the country; the oxygen sensor is installed on the three-way catalytic converter, mainly to detect the oxygen in the exhaust gas Concentration, and send a feedback signal to the ECU, and then the ECU controls the increase or decrease of the fuel injection quantity of the injector, so as to control the air-fuel ratio of the mixture near the theoretical value. Therefore, if there is a problem with the oxygen sensor, the mixed gas is easy to be too rich, which will cause an increase in fuel consumption, and the three-way catalytic converter is generally not easy to be damaged.
Oxygen Sensor. The oxygen sensor is a ceramic component located on the exhaust pipe of the engine, which is used to detect and control the ratio of oxygen to fuel. After using the oxygen sensor for a long time, the computer of the electronic fuel injection system cannot get the information of the oxygen concentration in the exhaust pipe, and the concentration of the mixture in the engine tends to be high, and the fuel consumption also increases. Therefore, the condition of the oxygen sensor should be checked regularly, and it usually needs to be replaced when it is 80,000 to 110,000 kilometers.
Brake system. If the fuel consumption increases, you can check the brake system, because if the brake pads do not return, the driving resistance will increase. In addition, if the wheels rotate abnormally, the speed of the vehicle will be affected, which will lead to an increase in fuel consumption.
Air filter, gasoline filter. If the air filter is too dirty, it will affect the intake effect, the mixture in the engine is too lean and the combustion is not sufficient, the power will drop, and the fuel consumption will increase. When the steam filter is dirty, it will provide an error signal to the control unit, resulting in increased fuel consumption, so the filter element must be replaced in time after reaching a certain number of kilometers.
Clutch. During driving, the clutch slips. For example, the speed of 50KM is increased to the 5th gear and the accelerator is pressed hard. If the rising speed of the engine tachometer and the speedometer is not proportional, this phenomenon will cause the car to lose power and increase fuel consumption. Accelerator clutch wear.
Cooling system. The cooling system is used to dissipate heat from the car. If there is a problem with the cooling system, it will cause the engine to overheat, affect the intake efficiency, and reduce the power. Moreover, if the cooling system cannot reach the normal working temperature, it will cause difficulty in ignition, insufficient combustion, etc., which will directly affect the increase in fuel consumption.
