1. The motor makes a whistling sound, which sounds like steam or air coming out of the motor. Typically, after hearing this sound, the engine will quickly lose power. Possible problem, engine overheats, check cooling system. The exhaust system is clogged, the suction pipe is leaking or broken.
2. When I stepped on the accelerator, I found that the acceleration was not obvious, there was a lack of power, and the engine made a hysterical noise. The times most likely to occur are when the engine is hot or cold, or when it is low on oil. The causes of these problems can be divided into air filter, spark plug, ignition wire, gasoline, fuel filter, carburetor, oil pump and other problems. Check if the air filter is dirty, if the spark plug is old and needs to be replaced, if the ignition coil is broken and if the gasoline is not clean, such aswater in the oil line. Also check the oil pump.
3. A very loud noise comes from the exhaust, which is very annoying. Sometimes a similar noise comes from the front part. The main problem is the exhaust system. Check if the exhaust pipe is broken.
4. The motor makes a kicking sound, like the sound of a pencil hitting the table. The sound increases as engine speed increases. The possible cause is that there is dirt inside the engine. It is recommended to change the oil, filter and clean the engine. Others may be a valve problem.
5. When driving, acceleration is normal and ignition may be normal. However, if you drive at a constant speed, you notice that the engine speed is too high but the speed still seems to be. unable to increase. Try checking the coolant. Oil pressure is too high or toolow. Check the pressure gauge. There may be a problem with the ignition time setting, which may also cause such symptoms. As with others, it could be a problem internal to the engine, such as a clogged EGR valve.
6. When the motor is running, it makes a clicking sound, as if something is hitting metal. When accelerating or driving, you may not hear anything. This may be caused by the cylinder valve, which can be changed by adjusting the valve. Lack of engine oil can also cause similar problems. Additionally, engine oil pressure is relatively low.
7. When accelerating, the engine will make a whirring sound, or it will also sound when decelerating. In short, the sound will change as the regime changes. The possible reason is lack of power steering oil, fill it up. The generator bearings could be damaged. Problems with the pumpPower steering and the water pump will produce similar noises.
8. When you press the gas pedal, you will hear a clicking noise coming from the exhaust pipe. The sound may not be very loud and the car will not run abnormally, as well as fuel consumption. will increase. It is recommended to check the muffler and exhaust pipe for damage.

Where is the JAC S2 engine number
I'm sorry I just saw your question, I solved it myself. I already have some knowledge about automobile electrical devices. Because the original generator was too expensive and I was reluctant to replace it with a new one, I took apart and opened the generator myself. I discovered that a set of solder joints from the internal rectifier diode were unsoldered and appeared connected but not connected. .I soldered it myself and the problem was solved. I use it now.
