How does it work? 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, 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.
They must be of a hardier construction because of the high pressures incurred during the air-compression phase, which presents both an engineering challenge and a costlier product. Also, the high pressures can make diesel engines difficult to start. The diesel engine undergoes a four-step cycle to complete one compression-expansion movement of a piston.
The first of these is the air-compression step; because the same amount of heat is kept in a rapidly shrinking space, it drives up pressure and temperature. In the second ignition phase, pressure remains constant as volume begins to expand. During the third phase, called the power stroke, the volume and pressure both decrease as the engine does work , ultimately powering the car. Finally, in the exhaust phase, the volume remains constant at its highest level, and then the cycle begins anew when air is drawn in for compression in the first phase.
Fuel for diesel engines is heavier than gasoline, because it is made from the residues of crude oil as opposed to the more volatile by-products that result in the formation of gasoline. Like regular gas, it comes in a number of grades that can be tailored to the needs of specific engines. Using the wrong diesel fuel can cause operational problems from poor starting to "knocking and pinging" to overly smoky exhaust.

It is a direct fuel injection system for diesel and petrol engines. Modern cars come with electric fuel pumps located inside the fuel tank. It creates positive pressure in the fuel lines and pushes fuel to the engine. The cars with electric motor pumps have electronic control unit ECU and is programmed with safety logic that will shut it off.
The term fuel injection is not a new technology and has been there since the beginning of auto industry. But due to the unreliability and higher cost it came to mainstream in s. It is because of fuel injection system you are able to start the engine instantly during cold days. Without it, we would still be setting choke and warming engines for several minutes and benching out more smoke and pollution.
Remember to go with the pumps that fit your vehicle perfectly. In case the pressure and the flow of fuel are low, then performance and emission related problems likely to happen. There are manufacturers who produce pumps that are compatible with various models and sizes and works under all driving conditions. You can browse through the large fuel injection pump catalogue in order to buy online. Moreover, you can compare the injection pump price in India offered from several manufacturers.
The fuel injection pump costs are dependent on whether you are looking for OEM or aftermarket pumps. Notify me of follow-up comments by email.
