Come on, old Teana. What's the reason why it's boring and can't be accelerated? What is the reason why Laotianlai (see the transaction price | detailed explanation of the model) is not fuel-efficient, stuffy and accelerated? There are several reasons why Laotianlai feels sultry and unable to accelerate when refueling: 1. Carbon deposit: Carbon deposit includes cylinder carbon deposit, throttle carbon deposit, spark plug carbon deposit, intake carbon deposit, etc. These positions are closely related to the power output of the engine. When there is too much carbon in the engine, it will reduce the ignition energy of the car, reduce the intake efficiency, and eventually lead to the reduction of engine power, resulting in the situation that the acceleration is weak and sounds stuffy. 2. Fuel system: adding an inappropriate fuel label (such as 93 plus 90) will lead to a decrease in vehicle output power and power; Or because the vent hole of the fuel tank cover is blocked, the fuel tank switch, fuel filter and the oil pipe between the fuel tank and carburetor are partially blocked, which can not meet the required oil supply, resulting in too thin mixture and weak engine acceleration. 3. Air intake: Air is one of the power sources of the engine. If the air filter is not cleaned in time for a long time, the combustible mixture will be too rich and the engine power will be reduced; If it is a vehicle with a turbocharger, once the turbocharger fails, even if the throttle is given, the engine will still be dull and unable to explode. @20 19
