The temperature is high in summer. Do I need to stop and rest after driving for a long time?

1. Some car owners may be more careful when driving, so they want to stop and rest after driving on the highway. There is really no harm in doing this, which can avoid the occurrence of high-temperature carbon accumulation in engine oil. But there is really no need to worry too much about the engine.

2. First of all, have a good rest. In a good mood, the temperature is high in summer, the physical exhaustion is high, and it is easy to feel sleepy at noon. Therefore, maintain enough sleep time to ensure energy.If you feel sleepy while driving, you should stop and rest in time, and continue to drive after clearing your mind. At the same time, people are prone to irritability in hot weather.

3. As the temperature rises, cars are prone to flat tires under prolonged exposure. In summer, tires are affected by high temperature, thermal expansion and cold contraction, and the internal air pressure rises, which is very easy to cause flat tires. In particular, if the car does not rest after driving for a long time, the temperature of the car tires will rise rapidly, resulting in flat tires.

4. If you find that the water in the radiator is boiling, you should stop the engine to idle, and wait for the temperature to drop before adding water. When the tire pressure rises due to overheating while driving, you should stop and rest. It is not allowed to deflate or splash cold water to reduce the tire pressure and temperature.

5. Therefore, the duration of driving in summer should be shortened, and parking should be stopped every hour to avoid car accidents caused by fatigue driving.

6. Don't drive with fatigue. In summer, the day is long and the night is short, the temperature is high, and the physical consumption is high. Especially at noon, it is easy to get tired and doze off. Therefore, it is necessary to maintain enough sleep time to ensure energy. If you feel sleepy while driving, you should stop in time, take a proper rest for a while, and continue to drive when your mind is clear.

What is the reason for the shaking of the 541 gearbox of Xugong shovel?

The most common reason for the serious carbonization of the engine and the shaking of the car is that the throttle valve is too dirty or the fuel injector has too much carbon.

When the vehicle is driving at low speed, there is a strange noise in the gearbox, and it still appears after acceleration and when hanging gears, which may be caused by poor gear meshing in the transmission. Generally comeIt is said that if the noise is small and uniform, it can still continue to be used. If the noise is uneven and loud, it should be removed for inspection, repair or replacement.

The reason for the engine shaking may be that the foot pad is damaged, it may be caused by the lack of cylinder, or it may be caused by serious carbon accumulation of the throttle valve. If the engine has abnormal shaking, you can check the foot pads, throttle valves, ignition coils, spark plugs and fuel injectors. The ignition coil and spark plug belong to the ignition system of the engine.

The reasons for engine jitter are as follows: engine cylinder deficiency: engine cylinder deficiency mainly refers to the abnormal operation of one or more cylinders of the engine, usually manifested as the car has obvious intermittent exhaust flow, and the exhaust pipe shakes violently, so the engine shaking can be clearly felt, sometimes accompanied by sudden noise. Sound.

When the engine is running at idle speed, hanging in low gear, slowly loosening the clutch pedal and slowly increasing the acceleration pedal to start, if you feel that the car body is obviously shaking, the clutch is shaking.

. The one-way clutch supporting the guide wheel in the hydraulic torque converter slips. ( 1) Fault phenomenon When the vehicle has a failure of poor acceleration below 30~50km/h, slow acceleration, and good acceleration after passing the low-speed zone, it is likely that the one-way clutch supporting the guide wheel in the hydraulic torque converter slips.

Motorcycle engine ventilation pipe oil

Pedal motorcycle engine oil port injects oil out, most of which are engine ventilation pipes Blockage, causing the pressure in the engine to not be released, caused by excessive pressure. Most of the ventilation pipes of the pedal motorcycle engine are on the cylinder head cover, and the other end is connected to the air filter. Check whether the two ends of the ventilation pipe are blocked.

If the oil is discharged from the ventilation pipe of the engine, check whether the cylinder cushion is damaged. The pressure in the combustion chamber enters the engine, causing the pressure in the engine to be too high, and the oil is squeezed out of the ventilation pipe. Sometimes if too much oil in the engine is added, it may also cause this situation.

Generally, the oil coming out of the engine crankcase ventilation pipe is caused by the increase in the oil level, or too much oil or the cylinder pad damage, piston damage, etc. cause the pressure in the engine cylinder to enter the crankcase.

If gasoline is sprayed, it is caused by the negative pressure fuel tank switch, gasoline pump or carburetor failure and the oil surface is out of control. If engine oil is sprayed, it is caused by too much engine oil in the engine, or gasoline leaks into the engine and mixes with the engine oil, causing the oil to become more and thinner.

The reason why the engine ventilation pipe of the motorcycle discharges the oil: when the engine is running after the motorcycle turns over, the oil will be discharged along the engine ventilation pipe; when there is too much oil in the engine or the oil used is of poor quality; the engine piston ring is seriously worn, resulting in ventilation through the engine when the lower exhaust The oil is released from the pipe.

Chang'an cs55's new engine is a little noisy?

The engine is overheated, check the cooling system. The exhaust system is blocked. In the exhaust system, check whether the exhaust pipe is broken. The vacuum tube is leaking or broken. The generator bearing may be damaged. The engine oil pressure is too low. The engine is overheated, the engine is carbonated, and the oil is not good, so it needs to be added to a higher grade of oil.

The normal vibration sound of each system component (such as the noise of the engine surface), the impact sound of the gear when changing gears, the intake sound and exhaust sound of gas as the working source, the gear meshing noise, etc. are all normal sounds. Abnormal noise (abnormal noise) can be divided into slight noise, general noise and malignant noise according to the impact on car performance.

Engine lack of cylinder: When the engine lacks cylinder, the car will show problems such as louder engine noise, unstable idle speed, abnormal shaking of the car body, etc. In this case, the condition of the cylinder and the working condition of the spark plug should be checked.

The engine makes abnormal noise, see if it is an engine failure. Its function is to convert the chemical energy of a liquid or gas into heat energy through combustion, and then convert heat energy into mechanical energy through expansion and output power to the outside world. The power of a car comes from the engine.

What's the harm if the operating temperature of the engine is too high?

If the engine temperature is too high, it will lead to reduced cylinder inflation and abnormal combustion, reduce engine power, and poor fuel economy.Gasoline engines are prone to premature combustion and explosion; engine parts will also accelerate wear due to poor lubrication, and even cause parts to be stuck or damaged. The engine power decreases.

The engine temperature is too high, resulting in excessive thermal expansion of the piston, the gap between the piston and the cylinder wall decreases or disappears, and the movement resistance of the piston increases, damaging the piston and cylinder wall. The normal gaps of other moving parts are also destroyed, and the wear is aggravated and even damaged.

It affects the following: First of all, the reliability of the parts of the engine itself. If used at too high temperatures for a long time, these parts are prone to failure. The second is the fuel inside the engine, which is easy to cause spontaneous combustion. In order to pursue low weight, modern engines will not use pure steel completely in the parts.

What are the dangers of too high or too low temperature in the car engine?When the temperature of the car engine is too high, the coolant will be boiling, and white smoke will come out of the engine compartment. If the temperature of the car engine is too high, the parts of the body will gradually expand, so that the gap between the moving parts will also be significantly reduced.

Under normal circumstances, the operating temperature of the engine is too high, which will cause boiling. The pressure in the coolant circulation pipe suddenly increases, and the temperature becomes higher, thus forming a vicious circle. If the temperature is too high, it will cause serious accidents such as pulling the cylinder. The normal working temperature of the car engine is between 85-105 degrees, which refers to the temperature inside the engine.

Finally, it will lead to the risk of spontaneous combustion of the engine. Once the water temperature is high, it is necessary to check whether the antifreeze is insufficient and whether the water pump and thermoster are normal., whether the fan can work normally, whether the water tank is too dirty and needs to be cleaned, whether the pipeline is leaking and other questions.
