Distrubutor pump is a type of injection pump with smaller design. The main purpose of the distributor pump, as a solution for vehicles with limited space.
How does an inline pump work?
The inline type uses one plunger for one injector, but the distributor type uses a single plunger for all injectors. The way it works, this plunger will press all the fuel in each fuel barrel alternately . The fuel barrel is placed around the pump shaft. When the pump shaft rotates, the plunger will press the fuel in the fuel barrel alternately ...
How does a crankshafy pump work?
The way it works, when the crankshafy rotates, the camshaft pump also rotates. The rotation of the camshaft will cause the cam to press against the plunger alternately. When the plunger is pressed against the cam, the fuel pressure rises immediately so that the fuel is sprayed from the injector. 2. Distributor pump type.

How does the pump duty work on a common rail system?
On the common rail system, to spray the fuel is regulated by the injector directly with the ECU command. So, the pump duty only ensures maximum fuel pressure so that once the ECU opens the injector, fuel can be atomized.
What is a continuous pump?
Continuous pump is an injection pump that is applied to the common direct injection system.
What are the two basic types of pumps?
These methods can be according to the energy conversion mechanism, the fluid type or application. Positive displacement and dynamic pumps are two basic types of pumps according to the mechanism of energy transfer. Let us first introduce the pump, its function and its application. Then, we will describe all the types of pumps.
What is a pump?
A pump is a machine to transfer fluids (liquids or gases), or even slurries, by converting the electrical energy into mechanical action.
How do centrifugal pumps work?
Centrifugal pumps are used to transfer fluids by converting rotational kinetic energy to hydrodynamic energy. Rotational energy usually comes from an engine or motor. The fluid enters the pump along to the rotating axis and then is accelerated by the impeller. Finally, it flows radially outward into the pump diffuser or volute chamber from which it exits.
Why do fluid particles not change their radial locations during their flow through a pump?
Fluid particles do not change their radial locations during their flow through the pump because the change in radius at the suction (inlet) and the discharge (outlet) of the pump is very small. This is why the name axial is given to this type of pump.
What is a turbo pump?
Turbopumps are the most commonly used pumps in the industry. The main moving part of turbopumps or impeller pumps is a rotor with several blades installed on a rotating shaft. Because of the action of blades, the moment of momentum of the liquid passing through the impeller is increased. These pumps are the most common types of pumps due to the simple structural elements, low ratio of volume to the input power, and numerous uses in the industry. All turbopumps are members of the turbomachinery family.
Why is a rotary pump slow?
However, the nature of the pump needs very narrow clearances between the rotating part and the outer edge, which causes a slow and steady speed rotation. If the rotary pump operates at high speeds, the fluid creates erosion, which ultimately makes larger clearances through which the liquid can pass, leading to reduced efficiency.
What is an axial flow pump?
An axial flow pump is a common type of pump that basically consists of an axial impeller (propeller) in a pipe. The impeller can be run directly by a motor, electric motor, or petrol/diesel engine.
What are the types of pumps?from whatispiping.com
Refer to the following charts that shows the major types of pumps used in industries:
What is a Pump?from whatispiping.com
As per Merriam-Webster dictionary, “a pump is a device/machine that raises, transfers, delivers, or compresses fluids by suction or pressure or both”. So a pump is a piece of mechanical rotary equipment that moves fluids/slurries from the inlet through the outlet to transfer fluid to a desirable location. It increases the pressure (energy head) of the fluid and imparts velocity (energy) to help in the liquid movement. Refer to Fig. 1 which shows various types of Industrial Pumps used in Processing Plants.
What is the force that moves fluid from pump suction to discharge called?from whatispiping.com
Kinetic Pumps. In Kinetic Pumps, a centrifugal force of the rotating element called an impeller, “impels” kinetic energy to the fluid, moving the fluid from pump suction to the discharge.
What is the discharge from an impeller?from brennen.caltech.edu
the discharge from the impeller has a radial component so that the head rise has a centrifugal component. Downstream of the impeller the flow returns to an axial direction and proceeds through a stator before exiting laterally from the pump. Figures 3 and 4 show a typical centrifugal pump for low specific speeds of orderN= 1 or less. The flow enters the pump axially (Figure 3), enters the impeller, exits the impeller radially (Figure 4) and is
What is the difference between a centrifugal pump and a positive displacement pump?from whatispiping.com
In the case of a positive displacement pump, the flow remains constant (at constant speed) even if the pressure is varied. Hence for metering services, positive displacement pumps are preferred. Flow can be varied by the use of either stroke adjustment or variable speed drive (VSD).
What is a positive displacement pump?from whatispiping.com
Positive displacement pump uses the reciprocating action of a piston or squeezing action of meshing gears, lobes or other moving bodies to displace the media (entrained in the cavity) from one area to another (from suction to discharge).
What is a centrifugal pump?from whatispiping.com
Generally, a centrifugal pump is used for high flow, low to a moderate head and low viscosity. Whereas, a positive displacement pump is used for low flow (constant flow), high head and high viscosity. In the case of a centrifugal pump, the flow varies with the head. In the case of a positive displacement pump, the flow remains constant ...
What fuels are used in mechanical fuel injection?
While methanol and nitromethane are common fuels, other fuels such as ethanol or race gas can also be used in mechanical fuel injection. Illustration of mechanical fuel injection expanded with the addition of an idle control circuit, barrel valve, and multiple nozzles feeding a throttle valve hat assembly.
What type of fuel injection is used in a gas engine?
Mechanical fuel injection works well for naturally-aspirated or forced-induction engines and handles most any type of fuel — gas, ethanol blends, methanol, and even nitro blends. Setups can range from simple single-nozzle systems costing a few hundred dollars through to systems costing tens of thousands of dollars.
What is an injector nozzle?
Injector nozzles to inject the fuel into the air stream going into the engine.
Why are injectors added to a multi cylinder engine?
Additional components are added for air and throttle control for power modulation. Additional injectors are added to provide fuel to each cylinder of a multi-cylinder engine with any number of cylinders, regardless of whether it is a two-cycle, four-cycle, or rotary engine configuration.
How big is a fuel pump?
Fuel pump size is important. Normal installations involve a fuel pump about 25- to 50-percent larger than the engine demand. Tuning is simple by controlling the amount of excess fuel bypass back to the fuel supply. In addition, the fuel pump should be fed with an adequate supply line to avoid inlet cavitation.
How does a fuel injection system work?
Mechanical fuel injection works with a simple throttle-controlled air valve and a fuel pump , usually running at one-half engine speed. After pulling fuel from a vented fuel tank, the fuel is delivered through a barrel valve that controls the amount of fuel with the position of the air valve. Fuel goes through the barrel valve, then through fuel lines, directly to the intake system feeding each cylinder. For tuning, simple jetting changes control how much fuel enters each cylinder. On normally-aspirated engines, a properly set up mechanical fuel injection system provides instant throttle response, which makes the system great for racing applications.
