How to solve Yutong bus engine shrinkage

1. If you encounter YutongIn the case of bus engine shrinkage, the best thing to do is to stop and check in time and find the root cause of the problem. If you are not sure how to deal with it, it is recommended to contact a professional car repair technician for diagnosis and repair.

2. The common solutions to water leakage during operation are as follows: replace the cylinder pad, water pump, water pipe and clamp the clamp, etc. If the cylinder head or cylinder body is slightly leaking, you can try it with water tank leak plugging agent. Please ask the master to repair the cylinder head, cylinder pad and cylinder block. The cooling water is polluted.

3. Insufficient amount of coolant, coolant leakage, coolant freezing. You should immediately check for leaks, replenish the coolant in time, and replace the antifreeze with good antifreeze performance. ( 3) The hole on the lid of the coolant storage tank is blocked.

4. On the other hand, high temperature may also cause the engine to overheat, resulting in an increase in the risk of spontaneous combustion of the vehicle.In view of this, the high-temperature problem of Yutong buses must be solved as soon as possible to ensure the safety and comfort of users.

5. Solution: Check the oil pressure and replace the parts if necessary. Aging of engine parts. Car jitter is also related to the aging of engine feet (also known as claw pads).

What is the reason for the sound of the Yutong engine guard?

1. When accelerating, the engine makes a hissing sound, or when it slows down, it also appears. In short, it changes with the RPM, and the volume changes. The possible reason is that the power steering oil is missing, fill it up. The generator bearing may be damaged. Problems with power steering pumps and water pumps will produce similar noises.

2. Equipped withFor turbocharged engine models, there must be a difference between the sound and the sound of a naturally aspirated engine; models with engine guards may also produce noise due to friction; after some car owners come into contact with different cars, it is likely that due to their lack of mechanical knowledge, they will identify the abnormal sound of the car to avoid waste. Time and energy.

3. The possible reasons for the rattling sound of the engine are as follows: it may be the valve sound of the engine, because the valve parts are excessively worn, resulting in abnormal engine noise. Maybe the pressure of the oil pump is insufficient. It may be the problem of oil viscosity. The oil will become more sticky in winter and not easy to flow, resulting in abnormal engine noise.

4. However, the biggest disadvantage of the metal guard is resonance and noise. If the chassis is really scratched, it is likely to cause deformation of the metal guard. If this is a necessary part, it will be installed in the original factory.

Yutong bus engine part name

Yutong bus is equipped with Yuchai engine. The indicators of the Yuchai national six engine carried by Yutong bus fully meet the requirements of the national VI regulations. Yuchai strictly controls the product performance, and the emission technology of several control indicators (such as CO, THC, PM, NOx) exceeds 30% of the regulations.

Does the questioner want to ask "What do the three major parts of a car company mean to have a Yutong bus"? The three key parts of the engine, transmission and drive axle. The three major parts are the core components of the automobile power system, and their performance and coordination directly affect the performance and reliability of the vehicle.

Yutong cars are more equipped with Yuchai and Weichai engines. Yutong car brands have good braking, and there will be no small horse and big cars.

Under the engine. According to the query of Pacific Automobile, the oil filter of the Guoliu Yutong bus is under the engine. The oil filter is located at the front top of the car engine, below the engine. Its function is to filter out impurities, glue and moisture in the oil and transport clean oil to each lubrication part.

Is the Yutong Zhongba 28-seat Yuchai engine noisy?

1. Big. The combustion process of Yuchai 4 diesel engine is relatively complex and requires higher pressure and temperature. When used in passenger cars, it will produce stronger vibration and noise, and the noise is relatively large. Yuchai 4t diesel engine is a diesel engine with superior performance. This engine adopts advanced technologies such as high-pressure common rail and electronically controlled oil supply.

2. Decibel. Yuchai engine air pump is a high-power motor, and the working noise is 50 decibels. Yuchai heavy engine is an engine suitable for buses, trucks, construction machinery, etc.

3. There are two main reasons. First, the part of the connection between the motor crankshaft and the connecting rod is worn, resulting in a gap, and there will be noise. This problem can be disassembled and applied a small amount of grease lubricant to this part.
