We've seen a lot of cases about cars, cars, engines, or auto fires, but we don't see much of the case when the engine doesn't put out the fire. The engine can not turn off the question, we need to look at a simple principle of vehicle system, we take Baotou North Benz engine accessories to a person, then the engine is at work when people go to work, so that people cannot flameout has been working overtime;

The first reason is that no one told him to leave the Office

Normally, when the ECU is powered on, it's time to start work after the electricity is activated, and the signal line sends a work order, so you can get off work. If the ECU does not receive the power signal, it will always work, this is a fault for us, the reason is some parts of our broken, or electric circuit in series, check this kind of fault is simple, check the activation power lines have normal voltage.

Another reason is to notify the engine that you need to work overtime

Here we need to imagine a scene, Baotou North Benz engine accessories is a department head, when the boss is our driver off the power of the vehicle, is issued to the engine can work orders;

But sometimes there is no way to directly off the engine, because other department staff requirements of the engine plus class will, otherwise will affect the whole company, this time the engine will add class command will receive.

Taking into account the car itself is a set, we is in normal driving, the key to the door after a power outage, vehicles can run normally, Baotou North Benz engine accessories will not stall, this is also a strategy for safety consideration.

When this fault, we can understand the engine received an error signal, because when the car has stopped smoothly, but the ECU received signal that this car is also normal driving, so the engine will need to add classes, that is when we need to check that the vehicle speed sensor etc.

We say again today that this vehicle failure, maintenance personnel have power line cut, the vehicle is still unable to stop, after the replacement of new ECU vehicles, the same failure is still, can not flameout.

After a period of investigation found that the broken brake insurance, the vehicle can be normal flameout, here we can think, belongs to the vehicle fault notification to work overtime, we try to break Trailer ABS, the vehicle can be normal flameout, here we find the cause of the failure, because the ABS is the vehicle and trailer is the exchange of information, the ABS can also provide a disguised signal to the engine speed

The third reason is that the "concubine Concubine" can not do it"

That is to say the engine is out of control, no error signal receiving circuit, other aspects are also normal, but the engine is not to extinguish the fire, the situation is usually diesel engine into the cylinder will occur inside in burning, this time is usually over a period of time, the oil burning after the fault disappears.
