Diesel Pumps an Inevitable Part for Diesel Engines

There are a lot of vehicles that use diesel as its fuel, as it is a comparatively cheaper option over petrol. In today’s world when the costs are ever increasing; you definitely want to ensure that you can minimize the cost of fuel. A diesel engine works due to the proper functioning of multiple parts among which the diesel pumps are the most important. These pumps play a vital role in ensuring that the correct amount of fuel is injected in a continued manner so that the engine can run smoothly. This means that the smooth ride that you enjoy in your diesel car is due to the pump working properly.

The diesel pump performs two important functions in the engine. As stated, the first one is providing a sufficient and continued supply of diesel to the engine to keep it running smoothly. The second one is controlling the fuel amounts based on the desired power output for the vehicle. So, if you want more power, the pump has to ensure that a higher quantity of diesel is injected into the engine at every instance. Unlike the gasoline engines, diesel engines do not have an ignition system; hence the diesel pumps become very significant. Most of the new technologies and advancements that have happened with reference to the diesel engines can be largely attributed to these pumps as they are major performance enhancers in the vehicle.

There are various types of diesel pumps or injection systems. These pumps are classified based on the way in which they introduce the fuel to the engine.

The popular pump types are as below:

In-line Pumps – These are mechanical pumps that are usually found in larger vehicles like trucks and other big vehicles used for construction. Also, known as jerk pumps, these have an inline mechanism wherein the body of the pump is designed in order to carry out two simple tasks. The first one is to ensure that there is the right amount of fuel pressure maintained to deliver fuel consistently and the second one is to ensure that the right quantity of fuel is pumped into the engine. Both the activities are driven by the camshaft.

Distributor Pumps – The distributor pumps like inline pumps are mechanical as well. However, these are preferably used in smaller vehicles. These pumps have a single fuel pressure mechanism, irrespective of the number of cylinders an engine has. Such pumps are designed in a way that they can ensure continued supply of the required amount of diesel to each cylinder. Such pumps can operate at high speeds as well, hence making it ideal for smaller and more compact engines.

Rotary Distributor Pumps – These are similar to the distributor pumps in the mechanism wherein a single pressure mechanism system pumps fuel to every cylinder. However, unlike the mechanical distributor pumps, these are electronic. With the help of a sensor, the pump is able to detect the amount of diesel that needs to be injected in order to ensure that the car runs smoothly. The pump consists of a sensor, an ECU (electronic control unit) and an actuator.

Common Rail Pumps – These are probably the most advanced among all the four. Such diesel pumps have been developed keeping in mind the need to keep the cleaner environment and reduce emissions by the engine. This is also an electronic pump that consists of a supply pump, common rail, multiple sensors which monitor the smooth functioning of the engine, electronically controlled injectors and an ECU to control all the other mechanisms and run them smoothly.
