Fuel Injection Pump Working Principle in Diesel Engine
There are two types of injection pumps on conventional diesel engines, inline pump and distributor pump.
We have discussed the difference between the two types of pumps in the previous article, you can access these 3 types of fuel injection pump in diesel engines.
in this article, we will discuss in detail about the inline injection pump.
How does it work ? what are the components? we will discuss it all.
Definition of Inline Injection Pump
Inline injection pump is a high pressure pump on a diesel engine that is used to increase diesel fuel pressure up to 18,000 PSI individually.
That is, each injector will be served by a plunger unit.
It can be said, in a 4 cylinder diesel engine there are 4 injectors and 4 plungers.
The main characteristic of the inline injection pump, lies in the configuration of each plunger. Each plunger is placed in line above a camshaft pump.
That's where the name inline pump is taken. In addition to being called an inline pump, this type is also known as the individual pump because, as explained above, this type uses one plunger for each cylinder.
The main component of the inline injection pump. There are 5 main components in the inline injection pump,
Rack and pinion
The camshaft pump is used to drive the plunger in order to press the fuel. While the fuel barrel, is the place to hold fuel that will be pressed to the injector.
This is the configuration, the plunger is located above the camshaft and the fuel barrel is located above the plunger.
Rack and pinion is a mechanism to regulate the amount of fuel in the fuel barrel. This mechanism will regulate the diesel engine RPM.
