The fuel injection pump is the heart and soul of a diesel engine. Precisely, the fuel delivered by the injection pump maintains the rhythm or the timing, which helps the engine to run smoothly. At the same time this injection pump controls the fuel amount required to generate the desired power. Basically the diesel injection pumps work both as the throttle and the ignition system that’s required in a gasoline engine. Since a diesel does not have an ignition system, the possibility of having any problem regarding its functionality can be avoided. Diesel fuel injection pumps are designed to inject an exact amount of fuel over a definite time. It operates at a very high pressure and therefore cannot tolerate even a miniscule amount of dust in its clean and polished interiors.
Field of Application of the Diesel Engine:
Diesel injection pumps are generally used in automobiles. The obvious reason behind the continuing success of diesel-powered vehicles is - diesels use considerably less fuel than its gasoline-powered counterparts. Further, when it comes to starting and running refinement, diesel is almost at par with gasoline. Even for exhaust gas emissions, diesel engine with catalytic converter is as good as a gasoline engine, if not better in some cases.
Well, such popularity of the high-speed diesel engine wouldn’t be possible without the diesel fuel injection pump. The extremely high level of precision inherent within the distributor pump indicates that it is possible to exactly meter the minute fuel injection quantity to the engine. With the help of the special governor installed with the VE pump in passenger car applications, the engine of the vehicle immediately responds even to the finest change setting of the accelerator-pedal. All these mentioned points contribute to sophisticated and difficult handling qualities of an automobile of the modern day.
The whole purpose of fuel injection pump is to deliver the exact metered fuel to the injector at the right time under high pressure. Unlike the gasoline-powered engine, the injector injects fuel into the cylinder directly or to a pre-chamber connected to the cylinder.
Important Features of Fuel Injection Pumps:
There are however, several notable features on a fuel injection pump that gives diesel engines certain characteristics that helps it to enhance the overall performance. Some of the most important features are as follows:
- Aneroid: The Aneroid limits black smoke on turbocharged engines at a low engine speed.
- Torque Control: The Torque control accurately matches fuel output with the requirements of the engine.
- Governor: The Governor controls the speed of the engine.
All the above mentioned features together with some more outstanding features help diesel engines of an automobile run efficiently when time wears out or the adjustments get troubled. However, there haven’t been much notable changes in the design of the diesel fuel injection pump over the past 25 years. The only change that most diesel injection pumps went through is the addition of a computer controlled solenoid that replaced some of the fuel flow control units.
