All diesel engines require a method of storing and supplying fuel to the engine, so a fuel supply system has been developed. Diesel engines are based on injectors, which have very tight tolerances and very small precision parts, so the fuel supplied to the engine should be very clean and free of contaminants.

JCB fuel and injection system performs the same function.

This article shall focus on telling you what the JCB fuel injection system is made of and what is the role of JCB fuel system.

Here are the main points of the article:

1.The function of JCB fuel and injection system

The JCB fuel and injection system performs the fuction of suppling the engine with fuel, and its storage and cleaning. 

2.The structure and work thory of JCB fuel system

The JCB fuel system is comprised by a fuel tank, a fuel pump, a fuel filter, an injection system form the fuel system.  

One of the main components of the diesel fuel injection system is high-pressure fuel pump. JCB HP pump plays the role of: injection under pressure of a certain amount of fuel; regulation of the required timing of the injection. 

The incoming fuel is cleaned in a JCB fuel filter.

The fuel system (connected by fuel lines ) must not only supply fuel, but also ensure cleanliness. Usually, this is done through a series of filters. For example, the fuel is filtered once by a filter outside the engine and then once by one or more other filters inside the engine. Most of these filters are located in the fuel pipe of each injector.

The fuel filter of the diesel fuel system has a pressure reducing valve that regulates the working pressure in the system. Excess fuel is diverted from the valve through the fuel drain line

The most vulnerable part in the fuel system is high purity fuel filter , because its capacity is broken due to low temperature. To warm up the JCB fule filter, overhead typeheaters are used.

The JCB injection system is a fuel-air mixture formed by fuel injection.

The fuel system works thory is as follows. When the ignition is switched on, the fuel pump pumps the fuel into the system. When fuel passing through the fuel filter, it is cleaned. Then the fuel enters the injection system, where the spraying and the formation of the fuel-air mixture occurs.

The fuel system of a diesel engine is much more complicated than that of a simple gasoline engine. Because fuel plays two roles. Obviously, one of the goals is to refuel the engine. The other acts as an ejector. To achieve the second goal, the diesel engine must continuously traverse the engine fuel system at a speed that greatly exceeds that of a single engine. Depending on the application, excess fuel is returned to the fuel pump or fuel tank.

3.The function of JCB fuel line


The fuel system is connected by series of fuel lines.

Fuel lines can be in various sizes and can be applied to different heavy equipments, from excavators, backhoes, liftforks, loaders to tractors.

According to actual needs, nylon fuel pipes will be made into different shapes.

Nylon is easy to use because it is efficient, easy to install and cheap. In addition, stainless steel is also a classic choice because it can withstand more wear and ripping.

Heavy-duty fuel lines can withstand the high pressure between the fuel injection pump and the fuel injector.
