What is the reason for the occasional lack of power when the Changan pickup truck is walking

The main factors of insufficient power are as follows:

1) Reasons for fuel supply: due to the blockage of the vent hole of the fuel tank cover, the fuel tank switch, the fuel filter and the oil pipe between the fuel tank and the carburetor, which cannot meet the required oil volume, resulting in the mixture being too thin and the engine working weak.

Due to the long-term use of the air filter is not cleaned in time, the blockage, the lack of air volume will cause the combustible mixture to be too thick, so that the engine power will be reduced.

The use of low-octane gasoline, the use of gasoline for too long, due to volatile deterioration resulting in too low octane number, easy to cause detonation, so that the engine power decreases.

Carbon accumulation in spark plugs and other parts increases fuel consumption.

There is water and air in the oil circuit, which will affect the smooth flow of fuel.

The muffler has too much carbon, which increases the exhaust resistance.

2) Causes of ignition system: ignition timing is inaccurate, ignition is too early, causing premature ignition and detonation of combustible mixture.

Due to the failure of the ignition system, the spark plug is broken or the spark plug spark is weak.

3) Compression pressure of the cylinder: the serious wear of the piston, piston ring and cylinder causes the matching gap of the piston, piston ring and cylinder to increase, and the sealing becomes poor, resulting in the leakage of the cylinder head and reducing the compression pressure of the cylinder.

Due to the poor sealing, the crankcase leaks, which reduces the suction power.

Improper adjustment of valve clearance, misalignment of valve timing, and tight valve closure affect the cylinder pressure and reduce the power of the engine.

4) Engine overheating: due to various reasons, the combustion of the combustible mixture is incomplete, so that the carbon deposit in the combustion chamber is excessive, resulting in poor heat dissipation, and the engine load increases to produce overheating.

5) Too much or too little lubricating oil in the crankcase, the lubricating oil deteriorates or is dirty, and the lubricating oil passage is blocked, which affects the power of the engine.

What's going on with the Changan pickup truck having no power.

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! Based on your question, make the following answers:

The causes and treatment methods of insufficient power are as follows. First, first check the air intake system, if the relevant air intake system is clogged or the air filter is too dirty, it will also lead to a lack of power, you need to clean the air intake system and replace the air conditioner filter. The second is the problem of the fuel circuit or the fuel injection head, which is recommended to check the pressure of the fuel pump and clean the fuel injection head.

The third situation is the problem of the related sensor, focusing on the differential pressure sensor. The fourth situation is exhaust blockage, which focuses on checking the particle trap, if it is blocked, it needs to be cleaned in time.

The second is the problem of the fuel circuit or the fuel injection head, this is recommended to check the pressure of the oil stuffy Xiang pump and clean the fuel injection head. The third situation is the problem of the related sensor, focusing on the pressure attack carry sensor.

The fourth situation is exhaust blockage, which focuses on checking the particle trap, if it is blocked, it needs to be cleaned in time.

The weakness of Chang'an state trembling car is likely to be caused by the fuel supply barrier: due to the blockage of the ventilation hole of the fuel tank cover, the fuel tank switch, fuel filter and the oil pipe between the fuel tank and the carburetor are partially blocked, which cannot meet the required oil volume, resulting in the mixture being too thin and the engine working weakly.
