The reliability of the car is down, and it can't run normally. For example: the engine suddenly flameout, can not start; power sudden drop, oil consumption obviously rise and so on.

2) abnormal sound

One part of the car sends out abnormal sound, and this kind of fault can be found and eliminated in time. Otherwise, it may cause large machine accident. Experience has shown that all sounds dull, and with obvious chattering phenomenon, that car may have malignant fault, you should immediately stop off, to find the reasons and ascertain the fault location. The abnormal sound is different because of the different parts of the fault.

3) overheating

The car in the work process, the assembly temperature exceeds the normal working temperature phenomenon. For example, the North Ben V3 accessories engine overheated, indicating that the cooling and ignition system is faulty. If it is not removed in time, it will cause symptoms such as early combustion, detonation, driving powerlessness and so on.

4) leakage phenomenon

Leakage usually refers to the leakage of fuel, lubricating oil, coolant, brake fluid and so on. Leakage can easily lead to premature wear of parts, damage of machine parts and failure of work.

5) exhaust abnormality

The exhaust emission from the exhaust pipe of the engine is not normal when the combustion is not normal.

6) abnormal consumption of fuel and lubricating materials

If fuel and lubricating materials are abnormally consumed, it is also a symptom of failure. Oil consumption is excessive, except for leakage, most of which are due to the large gap between engine piston and cylinder wall, which is often accompanied by a large number of smoke and pulse smoke at the oil inlet, and the color of exhaust gas is also abnormal. If the oil capacity of the North Ben V3 parts engine increases in work, it may be the leakage of cooling water or gasoline to the oil sump.

7) abnormal smell

If North Run V3 parts engine overheating or oil burning, clutch slipping seriously, and so on, will send out a paste taste. The wire ablation, short circuit ground when driving a smell, but found abnormal smell, should immediately stop the troubleshooting.
