Q & A

What is the purpose of the diesel fuel distributor-type injection pump?

The diesel fuel distributor-type injection pump is designed to regulate and distribute fuel to the injectors in the engine. It ensures that fuel is delivered under high pressure to each cylinder for combustion.

How does the feed pump function in the injection system?

The feed pump draws fuel from the tank and supplies it to the injection system, maintaining a pressure of 1.8 to 2.2 bar. This pump ensures the continuous supply of fuel to the injection pump.

What role does the fuel filter and water sedimenter play in the system?

The fuel filter removes contaminants from the fuel, while the water sedimenter separates water from the fuel. Both are essential for ensuring clean fuel reaches the injection system.

How does the distributor-type injection pump generate pressure for fuel delivery?

The injection pump uses a roller and template mechanism that moves in a combination of forward-backward and rotational motions. This movement creates the pressure necessary to pump fuel at high pressure to the injectors.

What is the purpose of the automatic timer in the system?

The automatic timer regulates the timing of fuel injection. It controls when fuel is injected into the engine cylinders, ensuring optimal combustion timing.

Why is the delivery valve important in the injection system?

The delivery valve acts as a one-way valve that directs the high-pressure fuel to the injectors. It also helps prevent the fuel from flowing back into the pump, maintaining consistent pressure.

What is the function of the injector nozzle?

The injector nozzle is responsible for spraying the high-pressure fuel into the engine’s combustion chamber. It ensures that the fuel is atomized properly for efficient combustion.

How does the mechanical governor regulate engine speed?

The mechanical governor adjusts the fuel supply based on the engine’s speed. By controlling the amount of fuel injected, it helps maintain a consistent engine speed.

What happens when the adjusting screw on the governor is turned?

Turning the adjusting screw on the governor alters the position of the mechanical governor, adjusting the fuel flow. This changes the engine speed, either increasing or decreasing it.

What is the role of the assisting lever in the injection system?

The assisting lever works in conjunction with the throttle to control the operation of the mechanical governor. It helps adjust the fuel flow to the engine based on throttle input.
