Various Parts and Functions of Diesel Injection SystemFuel injection system is at the very core of the diesel engines. By pressurizing and injecting fuel, the system forces it into the air which is compressed to an elevated pressure in the combustion chamber. Diesel fuel injection system comprises of the following:
Fuel Injection Pump: for pressurizing fuel to a high pressure
High-Pressure Pipe: for sending fuel to the injection nozzle
Injection Nozzle: for injecting fuel into the cylinder
Feeding pump: Sucks out fuel from the fuel tank
Fuel Filter: Filtrates the fuel
It is located right at the bottom of the filter for separating the water content from fuel.
Functions of the System:
The diesel fuel injection system has four main functions:
Feeding the Fuel:
Pump elements like the cylinder and plunger are built into the injection pump body. Fuel is compressed to an elevated pressure when cam lifts the plunger and then it is sent to the injector.
Adjusting the Fuel Quantity:
In the diesel engines there is constant intake of the air irrespective of the rotating load and speed. When the injection quantity is changed with the speed of engine and the injection time is constant, output and the fuel consumption tend to get changed. Engine output is proportional to the injection quantity which is adjusted by the accelerator pedal.
Diesel fuel injectors are more like a necessity if you have diesel fuel injection system. Given here are a few common symptoms that indicate you have faulty diesel fuel injectors for which you need to buy diesel injection repair kits.
Trouble in Starting the Vehicles or Uneven Idling:
The engine cranks but does not start unless you crank it for a long time. Engine uses different revs speeds on idle.
Misfire:
If vehicles are misfiring on ignition, a complete diagnosis involves finding the lacking combustion process element. In the diesel engine this is either a lack of combustion chamber heat or lack of fuel injection. Misfire happens when the fuel charge in one of the cylinders fails to ignite or when there is a low level of fuel pumping into the ignition.
Fuel Begin to Smell:
Small of the diesel inside the cabin implies that the diesel has a leak. This can happen due to faulty injector enabling the fuel to flow out of injector when it is not active.
Dirty Emissions:
Injector deposits and clogged filters can cause an uneven or incomplete fuel burn which can result in the area of the vehicle around the exhaust turns dirty and white smoke begins to get released from the engine. Clean fuel injectors are necessary for the optimal performance and efficiency.
