What are the 2 kind of injection pump?
The main types of injection systems include pump-line-nozzle, unit injector, and common rail. Modern injection systems reach very high injection pressures, and utilize sophisticated electronic control methods.
What is a ve injection pump?
The VE injection pump is a mechanically controlled, axial-piston rotary pump. It uses a vane-type supply pump to generate an internal pump pressure that increases with engine speed. It has a single pumping plunger, called a distributor plunger.
How do you time a Lucas injection pump?
For gear driven coolant pumps: Remove the coolant pump, see operation 21-3. 4 Insert the timing pin (B1) through the hole (B5) in the fuel pump gear and the slot of the hub (B4). Push the pin fully into the hole (B3) in the body of the fuel pump. If the pin can be fully inserted then the pump timing is correct.
What is injection pump unit?
The unit pump injection system (UPS) injects the fuel into the engine cylinder. It consists of an electronically controlled unit pump and a nozzle holder assembly connected via a precisely adapted high-pressure line.
How do I adjust my injection timing?
The most common ways to adjust injection timing are programming the ECM, adjusting the fuel injection pump, replacing the camshaft, and replacing the cam followers or gaskets.
What are the types of diesel injection pump?
Know Your Vehicle: The 4 Types Of Diesel Fuel Pumps
- Common rail fuel injection pump. An electronically controlled diesel fuel supply system, this pump was developed to meet the strict 21st century exhaust gas regulations.
- Distributor (rotary) fuel injection pump.
- In-line fuel injection pump.
- Distributor injection pump.
How does diesel injection pump work?
The fuel injection pump is the heart of the diesel engine. Precisely delivered fuel maintains a rhythm or timing that keeps the engine running smooth. Simultaneously, the pump also controls the amount of fuel needed to gain the desired power.
