Types of Fuel Injection Pumps
Individual Inline Fuel Injection Pump
It is an individual inline injection pump in which a plunger mechanism will perform each injector. In other words, the number of plungers is the same as the number of injectors. All these plungers are installed together in a line position in a pump unit, hence the name.
The inline fuel injection pump consists of the camshaft, plunger, and fuel barrel. The camshaft has the number of cams according to the number of plungers. A plunger works to increase fuel pressure. The fuel barrel is the small space where fuel is placed to be transferred to the injectors.
Distributor Fuel Injection Pump
It is small in size and used as a solution for vehicles with limited space. The main part of the distributor pump is its injection system. In the inline type, one plunger is used for one injector, but in the distributor type, one plunger is used for all injectors.
In this type, a plunger will alternately pressurize all the fuel in each fuel barrel. The fuel barrel can be found somewhere around the pump shaft. Pump shaft rotation causes the plunger to alternately press the fuel in the barrel when the ignition timing changes.
Continuous Fuel Injection Pump
The continuous pump is a modern type used as an injection pump that is applied to the general direct injection system. In terms of size, this pump is the smallest of the other two types of injection pumps. Due to this, it has only a single function.
Its primary function is to steadily increase fuel pressure to a high-pressure range from 30,000 – 40,000 PSI. In addition to increasing fuel pressure, the above two types control the timing and amount of fuel injected. So the form should be pretty straightforward.
Phasing of the fuel injection pump is the procedure of adjusting the fuel injection timing to reduce the torque fluctuations. The phasing of the fuel injection pump is generally done before the calibration.
The timing of the fuel injection is adjusted with respect to the position of the crankshaft. The phasing helps to reduce the torque fluctuation; thus it also reduces the gear impact noise.
Calibration of the fuel injection pump is carried out to ensure the same quantity of fuel is delivered to all the cylinders of the multicylinder engine. The calibration is generally done after the repairing or rebuilding of the fuel injection pump.
