What is the function of diesel leak off pipe?

 

What is diesel leak off pipe?

The Diesel Leak Off Pipe is a fuel system hose which is equipped on vehicles with carburetors. It’s mainly function is to return extra fuel from the carburetor to the fuel pump, it also has other important purpose.

The Diesel Leak Off Pipe mainly used when the injectors do not need more fuel in them to inject in the combustion chamber. And the excess fuel goes back to the reservoir tank through overflow pipes.

What is the function of diesel leak off pipe?

The function of Diesel Leak Off Pipe is protecting the fuel system, ensuring the normal diesel injector work and release excess pressure during the running of vehicles.


1.Protect The Fuel System

The fuel systems are equipped with Diesel Leak Off Pipes, protecting the fuel system better and prevent vapor blocking in the fuel system . The fuel pump is pumping gas from the fuel system at a much higher rate than is actually needed. This keeps gasoline in the fuel lines cool and flushes out any vapor bubbles that might form.

 

2.Ensure Diesel Injector Work  

The reason that diesel engine has a Diesel Leak Off Pipe is that the fuel is injected by the Injectors. So the Diesel Leak Off Pipe is also named as diesel leak off pipe. In a very dynamic and transient conditions, the load or need for fuel varies very radically. In that case, the diesel Injector may have extra quantity at a very high pressure due to the previous demand. This was one way thing the excess fuel comes out of the injector and back to the pump/filter depending on the vehicle.

 

3.The work theory of fuel injection systems (like all diesel have) depending on a high pressure pump to provide well timed high pressure fuel pulses to activate the injector and spray fuel into the cylinder. If any air bubbles find their way to the high pressure side of the fuel injection system it unlike fuel can compress and throw the fuel injection timing off.

 

4.Diesel leak off Pipe (also named Return Line)is used for returning of the excess fuel after injecting fuel into the diesel engine. As the Fuel Leak off Pipe is fitted in the injector nozzles, these pipes have to be highly precise and meet its fitment requirement, this requires the professional skill and precise production process for pipe assembly.

 

5.Release Excess Pressure  

 

There is another function that the Diesel Leak Off Pipe provides, is a pressure over flow port, in that way the fuel has some place to go when it gets too much pressure, and is released back to the tank.

In this way, the pressure of fuel can be kept in normal state.

The Lifetime of Diesel Leak Off Pipe

The fuel Diesel Leak Off Pipe function is taking extra gas out of the carburetor and return it to the gas tank. On mostly occasions, this fuel Diesel Leak Off Pipe is used during the running of the vehicle. The hoses on a car can be used for 10,000 to 50,000 miles based on the conditions that they are supposed to.
