When the vehicle has been used for a long time, it will cause a decrease in power. This is mainly due to fuel system, intake system and circuit system.
1, we all know that the oil circuit system is a very easy problem for cars. The amount of fuel entering the combustion chamber is insufficient, which may be caused by the blockage of fuel injection nozzle, the leakage of oil pipe, the decrease of gasoline pump power, or the blockage of the gasoline filter. Carbon deposition can not only cause blockage of fuel injectors, but also increase intake of oil in intake valve, combustion chamber and three way catalytic converter.
2, the engine of the car can run, except for oil and air, otherwise the engine will not be able to run smoothly. The most likely cause of the intake problem is the blockage of the air filter or throttle system.
3, the circuit system mainly refers to the power consumption of the ignition system. The circuit system generates high voltage electricity through the conductor to the spark plug, and the spark plug fires to ignite the mixture in the combustion chamber. Therefore, wires and spark plugs are most likely to cause poor ignition. The spark plug is a consumable and is fixed for tens of thousands of kilometers. As for the conductor, it may also lead to poor conductivity due to the relationship of service life.
The most important of which is carbon plugging, not only can cause power decline, but also easily cause problems such as bad acceleration, dull hair, oil, noise, cold car starting difficult, idling jitter, tail gas choking and so on. So we must prevent and remove carbon.
