These 7 parts will cause fuel consumption to soar

Car fuel consumption has always been a topic of concern to everyone. There are always coups to tell everyone how to save fuel. Do you know which parts of the car will directly lead to soaring fuel consumption? The following Xiao Bian share the basic causes of soaring fuel consumption.

1. The wear of automobile tires is an old problem. The wear of tires directly affects the grip of the tires becomes smaller, which is what everyone calls tire slipping. The entire power of the car cannot be used completely for car driving, but it is slippery. The form of wasting a lot of power; tire tire pressure is too low, due to the car's weight when the car tire pressure is too low, it will increase the tire and the ground contact area, resulting in power loss. You may be able to step out of the throttle and you can only start right now. Therefore, the use of tires is directly reflected in the increase in fuel consumption.

2 Before the spark plug encountered many customers did not change when the spark plug maintenance expired, requiring thousands of kilometers to run. In fact, this is a misunderstanding. Running thousands of kilometers more will not bring you much income. Instead, it will affect other engine parts. Spark plugs work long-term in high-temperature environment due to oxidation, the electrode gradually loses sharp corners and passivation, then the gap gradually increases, resulting in higher breakdown voltage, easily lead to fire off, resulting in poor combustion of the cylinder can not be more fuel Good conversion into power leads to increased fuel consumption.

3. Carbon deposition in automobile carbon cars cannot be solved with the quality of current fuels. The car's carbon deposition is not limited to the intake, valves, and cylinders, and the impact on the throttle can not be ignored. Throttle carbon deposition leads to increased throttle opening, increased intake air volume, increased fuel injection caused by the engine computer to increase idle speed; there is a failure of the air flow meter, it sends the wrong signal to the engine computer, the computer According to the signal, the injection quantity will increase. These two points directly increase fuel consumption, causing serious engine alarms.

4. Heat Dissipation System About 30% of the combustion energy in the engine's work is transferred to the coolant in the water jacket through the metal wall around the combustion chamber, and the heat is circulated. If the engine heats up poorly and causes the engine to overheat, the overheating will reduce the charging efficiency, the power drop, and the lubricating deterioration will increase the wear and the like; the cooling system cannot reach the normal operating temperature, causing ignition difficulties and insufficient combustion. These directly lead to increased car fuel consumption.

5. Oxygen sensor Oxygen sensor is not unfamiliar to many old drivers. The role of the oxygen sensor is simply to control the fuel injection according to the combustion conditions of the exhaust gas. The oxygen sensor is divided into a front oxygen sensor and a rear oxygen sensor. The front oxygen sensor monitors the combustion of the engine and the rear oxygen sensor monitors the three-way catalyst. Sensor failure, resulting in misalignment of the engine's loop, sending an error signal to the engine's control unit, largely wasting fuel and not directly leading to engine failure.

6. Driving habits Everyone's driving habits are different. Those who will affect fuel consumption, such as like the throttle, the engine has just started launching a few feet on the throttle, before stopping the flames also a few foot throttle, even in the engine oil circuit or circuit work When it's not normal, it also hits the throttle with a few feet; the car is too fierce, and the brakes are stepping too hard. Drive like to grab the road, love emergency braking. Accelerating natural use of fuel more quickly, and after the emergency braking, the vehicle will consume about 12 mL of fuel once it is restarted. After the car shifts gears, it likes to put the left foot on the clutch for a long time, causing bumps and uneven feet due to uneven pavement. It is likely that the clutch will be in a semi-linked state; there are dragging and driving, "trailer" driving will increase the engine load, resulting in engine temperature is too high, lack of power, serious damage to the life of the engine, and the speed does not come, but also in vain .

7. The clutch plate is too thin. The serious wear of the clutch plate will lead to the increase of the combined stroke. There will also be a serious phenomenon of clutch slippage. The sense of power is obviously insufficient, the throttle is very high and the speed is high, but the car is not going. Just think of this state of the car can not spend it!
