What is the reason for the power reduction of Cruze engine? What is the reason for the power reduction of Cruze engine? The following are the specific reasons for the power drop of Cruze engine: 1, Three-way catalyst blockage: Three-way catalyst blockage will lead to poor exhaust, power drop and increased fuel consumption, and in severe cases, the engine will shake or even stall. 2. Dirty air filter: Dirty air filter will lead to insufficient air intake, decreased automobile power and increased automobile fuel consumption, which will easily lead to dirty throttle and carbon deposition. 3. Spark plug failure: Spark plug failure will cause vehicle idling jitter, obviously reduce power, increase fuel consumption, and a series of symptoms (such as shooting, black smoke from exhaust, serious vibration, etc.). ) may happen. 4. Nozzle carbon deposit: Nozzle carbon deposit will lead to insufficient power, idling jitter, difficult start-up and increased fuel consumption. Generally speaking, the reason why the fuel nozzle is blocked is that the carbon generated in the engine is deposited on the fuel nozzle or the impurities in gasoline are blocked on the fuel nozzle. 5. Throttle carbon deposit: Throttle carbon deposit is the main factor that affects throttle operation. Failure to clean the throttle for a long time will lead to an error in the throttle opening, and air with impurities will enter the engine cylinder, resulting in abnormal engine operation. The engine power drop may be caused by carbon deposit, fuel system failure or air intake system failure. There are many kinds of carbon deposits produced by engines, including cylinder carbon deposits, throttle carbon deposits, spark plug carbon deposits, intake carbon deposits and so on. These faults are all factors that affect the engine power. When there is too much carbon in the engine, the ignition system of the automobile will be deviated, the intake efficiency of the engine will decrease, and finally the engine power will decrease, and the automobile may be unable to idle at @20 19.
