[Xiagong Chu Sheng original] National three standard trucks are basically electronically controlled diesel engines, compared to the second country's engine, the operating instructions on a lot of strange new terms and terms, these may be difficult for many drivers to understand The forum netizen “Crowbar” started repairing the car from the age of 14. He used his experience to tell the drivers of the country’s three cars what they need to pay attention to and how to check for failures.

Now China's trucks are basically electronically controlled diesel engines, and many key products are imported high-end technology and then domestically produced parts, and the quality is very good. But why did the Euro 2 engine fail? Are there many Euro III problems? The younger brother has a lot of experience. The younger brother is a repairman who is covered in oil and has a small black face. Please don't laugh at me. I started to learn to repair cars when I was 14 years old.

  Question one: The engine cannot start.

The diagnostic instrument was used to measure the data, and it was found that the rail pressure could not reach, or that the high pressure and low pressure leaked. The inspection was checked and there was nothing. what is the problem? Please turn on your injector high pressure connector and take a look and the problem is there. The buddies do not have any high-end equipment. Xiuou Sanche has always been an empty hand. Is the old way, broken cylinder, parts interchangeable.

  Problem 2: After the engine is started, the speed cannot be increased.

Experts say this is a limp. I didn't go to school. I don't understand. All I know is that this is a bad injector. Look at the oil return.

  Question 3: After the engine starts, the fault light is on.

The old method, power off, and Other computer programs to restart to see if there is, the basic problem is the line, open the circuit board to see just fine, domestic car line is chaotic, imported cars and no technical information. It's good for the people, at least give you information.

  Question four: pay attention to check the fuel tank

Many people always say that if the engine is broken, check the engine, but the fuel tank can't be ignored here. Look there, I remember repairing a car and finding a complete plastic bag from the fuel tank tubing.

  Question 5: Do not step on the accelerator when starting

The throttle is squeamish. The throttle sensor is not sold. It is hateful. In fact, changing the throttle sensor will solve the problem. However, it is not found in China. The reason is that the foreign company will let you buy the whole product and will not let you buy the sensor.
