zg24 engine common disease

1. The combustible mixture is too thick.There is too much oil in the engine fuel. The piston ring or crankshaft oil seal is poorly sealed. There is moisture in the fuel. Spark plug poor air filter is too dirty, troubleshooting elimination, inspection and diagnosis of too thick combustible mixed gas, should focus on checking the carburetor and air filter.

2. Hello, the quality of fuel is too poor. For example, there are too many impurities, heavy metals, moisture, etc. in gasoline, which is easy to cause stinky exhaust emissions.

3. The air filter is blocked. The fuel injector has poor atomization. The time of fire is not accurate. The cylinder is worn and the cylinder pressure is insufficient. The valve is not tightly closed. The timing of the gas distribution is wrong. System feedback error. The load is too large. ...... It is recommended to check and overhaul.

4. Clean the oil line and check whether the idling motor has carbon accumulation that should be cleaned. Check whether the spark plugs have too much carbon and replace the spark plugs.Check the oil pressure and replace the parts if necessary. Replace the parts.

5. Engine body and piston connecting rod mechanism (1) These failures will cause the power of individual cylinders to drop horizontally, resulting in an imbalance in the power of each cylinder.

ZG24 engine idling jitter

1. The engine carbon accumulation is serious.The most common cause of idling jitter is excessive carbonisation of the throttle valve or fuel nozzle.

2. The main reason for idling jitter: serious engine carbon accumulation: cars always have the problem of carbon accumulation, including cylinder carbonization, throttle valve carbonization, spark plug carbonization, intake carbonization, etc.

3. Check whether the ignition system is faulty. Generally, it is caused by the ignition coil or the aging of the spark plug. It is enough to replace the damaged ignition coil or spark plug. The inspection of the ignition coil needs to read the specific fault code with the computer. If the corresponding cylinder has a misfire, it is generally a problem with the ignition coil.

Do I need to remove the front cover to change the cylinder pad of Dongfeng Ruiqi zg24 engine

The cylinder head comes out of the upper part of the seat, and the main and co-driver's seat and the rear iron cover need to be removed.

Of course, it needs to be replaced. Even if the cylinder cushion is not damaged during maintenance, it must be replaced with a new one, otherwise it is easy to leak, and the water will enter the engine oil pan.

There is no need to lift the engine to replace the cylinder pad, just replace it directly in the car. First, remove the accessories on the valve chamber cover, then remove the valve chamber cover, then remove the cylinder head, and finally change the cylinder pad.

If it is put in the past, replacing the cylinder pad is like a human operation, which belongs to the scope of overhaul. In the past, when the automobile maintenance technology was not mature, it may have some impact on the subsequent use of the engine. However, with the gradual maturity of processing and maintenance technology, changing the cylinder pad has little impact on the engine.

If the cylinder pad of the car engine is broken, the engine will not work normally. Use a torque wrench to unscrew the cylinder head screw in the order of the first, middle and the back ends of the original car. After removing the cylinder head and the bad cylinder pad, replace it with the new SF cylinder pad. There is no need to hoist the engine down. When installing the cylinder head, the cylinder head should be positioned with positioning bolts first.

How to solve the problem of the fault code of the ZG24 engine camshaft sensor even if it is replaced with a new one?

Because the fault code was not cleared on the computer board before installing the new camshaft position sensor. After clearing the fault code on the computer board, install a new camshaft position sensor to solve the problem.

Due to the engine camshaftThe fault of the position sensor will always produce the corresponding fault code, so it should be detected and repaired according to the corresponding fault memory during maintenance. For temporary faults, the breakpoint can be found by shaking the wire during the measurement process.

I will give you a suggestion according to the problem you reported. First, exclude whether there is a fault measurement method in the line. The camshaft sensor has three wires, one iron wire, and two power supplies are measured by disconnecting the plug, both of which are five volts. If there is no problem with the line. It is recommended that you check the signal disk again.
