He said fuel, should be most concerned about it. In addition to the usual driving habits. There are many car silently to increase your consumption of "gas guzzlers" who hundred small and quickly tell you about it.

 

1. Tires

In fact, the loss of fuel mainly in a variety of resistance, if the speed at 100km / h, the resistance of the tire will account for 25%, so that if the tire pressure is too low, the tires will increase the ground plane, friction increases, resistance is increased, fuel consumption will go up.

So remember to check tire wear, tire wear if serious, will often slipping, fuel consumption will also increase, usually every 50,000 kilometers, must go for a set of new tires.

 

2. Oxygen Sensor

Oxygen Sensor is a ceramic element is located on the engine exhaust pipe, the ratio of the detection and control of oxygen and fuel used.

Use a long time after, the oxygen sensor is prone to silicon poisoning, in the event of computer electronic fuel injection system can not get the oxygen concentration in the exhaust pipe information, mixture concentration tends to be high in the engine, fuel consumption will also increase. Usually 8-11 ten thousand kilometers when it needs replacing.

 

3. coke

Too much coke is mainly because of the use of oil caused by the poor quality of the coke-like material in which the unsaturated hydrocarbon and gummy impurities produced at high temperature, let the intake pipe wall roughening affect intake effect and mixed gas quality, so fuel consumption rose sharply. So carbon preferably every six months to clean up once.

 

4. The spark plug

The function of the spark plug is thousands of volts of high-voltage into the combustion chamber, and the spark to ignite the mixture. If the damage cause ignition energy decreased mixture combustion uneven, resulting in the car to slow down the speed, fuel consumption will rise.

 

5. Battery

Battery is oil tiger, we must not think of it. In fact, close to the circuit and oil was beyond imagination. When the battery operating time 2--3 years, there will be loss of electrical phenomena, leading to lack of start-up voltage, motor driven relatively weak engine, the spark plug could not get out a strong spark ignition energy so low, fuel consumption will therefore soar.

 

While in the case of power shortage, the oxygen sensor and the injector does not work the same mixed gas partial concentration, fuel consumption will go up.

 

So a lot of components to time in respect of change, never will, that this is actually saving money is more money wasted.
