If you suddenly discover more fuel than usual 10% or more, it may mean the car has a problem, the proportion occupied by these factors and sometimes even more than 60 percentage, so it please be treated with caution. Increase in fuel consumption is not only the driving habits and road conditions, there may still be some car failures yo. Car guru to share the following may cause increased fuel consumption of six main reasons. Do you have any questions, just ask me.
1. The spark plug
The function of the spark plug is thousands of volts high voltage into the combustion chamber and spark ignite the mixture. If the damage cause ignition energy decreased, uneven burning mixed gas, resulting in slowing down the car speed, fuel consumption rises.
2. Clutch the number of revolutions
of the engine clutch slip will be lost. Discovery engine tachometer increased rapidly, but the speed increase is very slow, when the clutch slip may be determined when you rapid acceleration. We need to replace the clutch disc, the clutch pressure plate and the drive wheel.
3. Coke
too much carbon is mainly because of the use of poor quality due to oil, which unsaturated hydrocarbons and coke-like substance with colloidal impurities generated at a high temperature, the intake air will become rough wall, affect the intake air mass and mixing effect, so that a sharp increase fuel consumption. So carbon preferably every six months to clean up once.
4. Tire
In fact, the loss of fuel consumption mainly in a variety of resistance, if the vehicle speed is 100km / h, the resistance of the tire will be accounted for 25 percentage, so if the tire pressure is too low, the tires will increase the ground, friction increases, resistance increases, fuel consumption will go up. So remember to check tire wear, tire wear if serious, will often appear slip phenomenon, the same fuel consumption will increase, generally every 50,000 kilometers, must go for a set of new tires.
5. The oxygen sensor
The oxygen sensor is a ceramic element located on the engine exhaust pipe, and proportional detector for controlling the oxygen and fuel.
timeAfter long, the oxygen sensor is prone to poisoning silicon, event, computer electronic fuel injection system information can not be obtained in the oxygen concentration in the exhaust pipe, the concentration of the mixed gas in the engine tends to be high, the fuel consumption will also increase. Usually need to be replaced in the 8-11 million kilometers.
Also in case of power shortage, the same injector and the oxygen sensor does not work, partial concentration gas mixture, the fuel consumption will go up. So a lot of parts in relation to the time change, never will, that this is in fact the money is more a waste of money.
6. Battery
batteries are gas guzzlers, we certainly did not expect it. In fact, the oil circuit and close beyond imagining. When the battery usage time reaches 2–3 years, there will be loss of electrical phenomena, resulting in insufficient starting voltage, motor driven engines relatively weak, unable to jump out of the spark plug spark strong, so that the ignition energy is low, fuel consumption will therefore soar.
