What is the reason for the decrease in engine power

There are often the following reasons, for reference only: 1. The sensor is damaged, the contact is poor or the signal is interrupted; 2. Poor engine maintenance; 3. The quality of fuel and oil is not good; 4. The combustion of the mixture is insufficient; 5. Spark plug failure, ignition coil failure; 6. The fuel pump is faulty and the oil circuit is blocked; 7. The air conditioner filter is blocked. The specific situation is analyzed as follows; 1. Sensor problems; The sensors mentioned here include water temperature, crankshaft position, air flow, intake air temperature, oxygen sensor, etc., when these sensors are damaged, poor contact or signal interruption, the ECU of the car can not accurately obtain the engine data, at this time it will cause the engine fault light to turn on.

2. Maintenance problems; Poor engine maintenance is the most common cause of engine failure to light up. We know that the vehicle has a certain maintenance cycle, if the owner does not maintain on time, coupled with bad driving habits, then it will increase the burden of engine operation, and finally can only remind you through the fault light to care about your car 3, oil quality problems; The oil quality here includes fuel and engine oil, we know that the fuel filled by the car is generally marked, and the engine oil is also semi-synthetic and fully synthetic, the manufacturer will generally recommend the owner to use which grade of fuel, which type of engine oil, if the owner does not add as required, it will cause wear and tear of the engine in the long run, and the fault light is not to blame. Poor combustion of the mixture; The failure of the spark plug, ignition coil, fuel pump, and oil circuit blockage of the engine will cause poor combustion of the engine mixture.

Poor combustion of the mixture is caused by the problem of engine carbon deposition or knocking, and these will eventually be detected by the engine's oxygen sensor and reported to the ECU, which will naturally turn on the fault light to warn of the intake air intake problem; When the engine burns, it needs to take intake, the air filter element is very important in this process, if the air filter element of the car is not clean, it will affect the air intake of the car if it is not cleaned regularly, and it will be blocked for a long time, and if it is serious, it will cause the engine failure light to turn on. pressurization issues; Intake booster lines and turbochargers can also cause engine failure lights to illuminate. The most common of these is turbocharger damage, and at the same time, the vehicle will also have oil leakage, large oil consumption, and power loss.

The common reasons for the decline of engine power are: too much carbon deposition in the engine, resulting in insufficient air intake; The fuel supply system is not smooth, etc.

Excessive carbon build-up in the engine: Excessive carbon build-up in the valves and intake ducts is the most common cause of a car's power loss. The solution is to find a professional auto mechanic to help clean up the carbon deposits and check if the nozzle needs to be replaced.

Fuel supply system is not smooth: check the fuel supply system, whether there is blockage or gas resistance in the fuel pipeline, whether the gasoline pump is working normally, whether the oil level height of the carburetor float chamber meets the specified requirements, whether the air filter is blocked, whether the exhaust system is blocked, etc.

Poor tire pressure of automobiles: Poor tire pressure is also one of the reasons for the decline of automobile power, especially when the tire pressure is insufficient and the number of people is large. Therefore, when the tire is inflated, it must be filled enough, and it should be filled according to the tire pressure gauge marked on the body.

Summary. Hello, I am your exclusive technician, attentive, careful, dedicated to answering your car questions, for you to find the corresponding problem solutions and solutions to the engine power decline The following reasons are first, too much carbon deposition in the engine leads to too much fuel injection Second, the spark plug gap is too large, and the third throttle needs to be replaced, the throttle is dirty, and the fourth is needed, the engine lacks cylinders, and the ignition coil needs to be replaced. Personally, it is recommended to replace the spark plug first, clean the throttle, and clean the engine before getting out of the car. Hope mine is helpful to you.

Hello, don't worry, I can ask for your question, but wait a minute, I need text for about 2 minutes.
