With the rising popularity of electronic control engine, the right of electronic-controlled engine maintenance is extremely important, but at the time of engine working, avoid by all means remove the high pressure side all tubing joints, high pressure oil pipe, for example, common rail pipe and so on.

The common rail tubing is very high pressure and must be disassembled after the engine stops.

Now the high-pressure common rail diesel engine is at work, its fuel pressure can reach up to 2,000 bar, its pressure is equivalent to a luxury car to pressure on the area of a fingernail.

Under such high pressure, once remove common rail pipe joints, high speed jet fuel is bound to produce cutting effect, high pressure liquid than the knife is sharp, once into the human body or eyes consequence is unimaginable

Correct method: after the engine is out of fire, wait for a while, after complete relief, remove and repair.

Therefore, in the inspection, once the drum roll should be replaced in time.

Many truck drivers at the same time check the tire pressure in the process of driving, often get off through the tapping tires with a crowbar and judge whether the tire pressure is normal, at this time due to wheel temperature on the high side, tire pressure on the high side, crowbar impact tires will exist a high risk of puncture, and truck tire pressure is generally high, once the force generated by a flat tire is very big also, if the tyre bulge, once the shock is more likely to cause a blowout, which lead to injuries are common.

Correct method: once the tire is found, please replace it immediately. Check the tire pressure and use the special barometer.

In addition, some car engines need to be pointed out that the ECU needs to receive the signal of the empty switch. Some models have the phenomenon of the short switch of the gap switch, which greatly increases the risk probability.

Correct method: confirm the stall and follow the operation procedure strictly.
