Can the National V truck turn off the electric brake immediately after stopping?

The national five trucks can not be turned off immediately after parking, because most of the national five trucks use urea pumps, after the parking urea pump to the pipeline of urea ** into the urea compartment, parking immediately off the power switch after power, the urea in the pipeline can not be crystallized into solid particles to block the pipeline and nozzles.

1. How to operate correctly.

The power off here refers to keeping the off position without screwing the key after turning off the engine, and then pulling out the key after 15 seconds. Because the urea pump has to be emptied, it needs to idle for 90 seconds when it is stopped normally.

2. What is a vehicle power outage?

The so-called power failure refers to the power failure of the whole vehicle, the general car is not equipped with a power main switch, and the key can be pulled out directly, because most of the cars are equipped with a power failure delay, but it is not guaranteed that all are equipped, but the hazardous chemicals car has a power supply switch, and all the electricity is cut off after the power is off, even if there is a delay, it is useless, so to distinguish the performance of the car, some cars are not to pull out the key, but to cut off the total power supply.

Third, the role of urea pump.

The urea pump is an important part of the urea solution jet metering system, and its main function is to pump the urea solution in the urea tank, and maintain a certain pressure, and then transport it to the injection unit to meet the requirements of the jet metering system for flow and pressure.

The amount of urea ejected by urea under different pressures, that is, the urea that the truck driver said, some burn less, and some burn more. Urea is injected into the exhaust gas discharged from the engine through the urea pump, and the exhaust gas meets the emission standards required by the state through chemical reaction. There are three tubes on the urea pump, one for urea, one for urea, and one for urea.

So it's really important for drivers to clean the exhaust pipe regularly.

Fourth, develop a good habit of using a car.

If the electric switch is closed directly, it is easy to cause urea crystallization, and the urea pump will burn after blockage. Large trucks are worth a lot of money, as a driver must strictly follow the vehicle instructions to operate, generally the instructions will clearly state how to turn off the electric brake, including waiting time.

It is not possible to add urea, because after stopping, the urea pump should put the urea in the pipeline into the urea compartment, and the urea in the pipeline cannot be crystallized into solid particles after the power is turned off immediately after stopping, blocking the pipeline and nozzles.

When the diesel car is on fire, it is necessary to cut off the oil and power, it may be that the oil is cut off because the solenoid valve or the flame-off cable is broken.

Whether it affects the welding or not, you will know. The reason why the main gate should be closed when welding on the car is because there are many electronic devices on the car now, and various controllers and the like are weak current equipment, which can only pass a small current, while electric welding is a large current, once it has an impact, it burns out these weak current equipment, but this is not necessarily burned out. Therefore, it is known from the beginning after the welding is completed.

Some controllers require more than just disconnecting the switch.

You need to remove the cable of the controller directly.

Generally, trucks use wet water and electricity batteries, and the main power switch is turned off when the vehicle is parked in order to place excessive power loss.

Not necessarily. The stalling of the truck depends on the situation. Because most trucks now have superchargers, and superchargers need to be cooled. If you are driving an empty car, you can turn off the engine immediately.

Fully trailer flatbed trucks are mainly used for short-distance bulk and heavy cargo turnover transportation in factories, warehouses, docks, logistics centers and other fields.

The full-trailer flatbed truck mainly uses solid tires, no puncture, strong load-bearing capacity, simple structure, easy maintenance, low cost, and free design, which is an excellent choice for short-distance transportation of bulk and heavy goods that do not need to be listed on the road.

Drive train: transmits the power of the engine to the drive wheels, mainly including the clutch, gearbox, drive shaft, and drive axle.

Driving system: connect the various assemblies and components of the car into a whole and support the whole car to ensure the normal driving of the car. It mainly includes frame, front axle, wheels, suspension.

Steering system: to ensure that the car can drive in the direction selected by the driver in the process of driving, mainly including steering control mechanism, steering gear, steering gear.

Brake system: to slow down the car, stop and ensure that the car is reliably parked. It mainly includes brake control mechanism, brake, transmission device.

Because your description of the problem is too simplistic to help you diagnose the exact cause of the failure. It is estimated that the button you pressed is broken, and the failure of the button can be eliminated by replacing it, or the button you press has an on-stop function, that is, it is open when you press it, and it is stopped when you press it again. The equipment that can make noise when the bottom of the bathtub is running should be a circulating or surf massage pump, and it is estimated that the button is to start the pump.

Hello, I am your exclusive technician, attentive, careful, dedicated to answering your car questions, for you to find the corresponding problem solutions and solutions! In this case, it does not mean that the urea pump is damaged, in this case, the pressure of the urea pump is not established, and the second is the distance traveled, the exhaust temperature does not reach the standard, the temperature is not reached, and the urea pump does not have the pressure in the working room, so in the state of you turn off, it does not have a clicking sound.

Question: I have started twice, and there is no sound after turning off the engine, is the pump broken? Answer: Start twice, have you started your vehicle twice, and the vehicle needs to be driven when the exhaust temperature reaches about 180 degrees? The urea pump only begins to build up pressure.

Is the battery still charged in the idle state after the truck's electric brake is turned off? When idling, of course, the battery is charged, as long as the engine starts the battery will be charged.

** High temperature will be generated, and when the neutral wire and the live wire are twisted together, a large area of ignition will be generated. When **, such as cutting off the power supply, the wire will not be short-circuited when using water to fight the fire.
