What is the reaction when the vacuum tube of the car is broken?

1, the rupture of vacuum hose will lead to excessive mixture, high idle speed, poor start of hot car, engine surge during acceleration, obvious increase in fuel consumption and black smoke from exhaust pipe.

2. Blockage will cause idling drift, and idling will easily turn off.

3, usually on the gasoline engine, there are several vacuum tubes at the intake manifold:

A, brake booster vacuum tube, this tube is broken, there is no brake booster, which is very dangerous;

B, power steering vacuum tube, this tube is broken, there is no steering power, which is also very dangerous;

C, carbon canister vacuum tube, which will pollute the air if it is broken;

D, crankcase ventilation system pipeline rupture, there is no danger, will pollute the air.

E, supercharged engine, will take pressure in this part to control the waste gas valve, is broken, supercharger is not working properly, will overspeed.

Extended data:

Generally, there are two kinds of vacuum tubes in the car, one is for the brake booster pump and the other is for the ignition advance device of the distributor. Their purpose is to provide vacuum for one side of the working pump membrane, and the other side is communicated with the atmosphere, so that the pump membrane drives the push rod to move forward under the pressure of the atmosphere, thus playing a role in boosting.

1. There is a vacuum booster pump that needs vacuum in the braking system.

2. Some variable inlet technologies require vacuum control.

3. Some cruise systems need vacuum control.

4. Removing fuel vapor from activated carbon tank requires vacuum.

5. Crankcase ventilation system needs vacuum.

6. In some air conditioning systems, vacuum is needed to switch air ducts. The vacuum tank is actually a sealed tank. Connect the vacuum tube to the intake pipe of the engine. When you use a vacuum in a car, you can take out a vacuum source from this vacuum tank.
