Takeaways

• 😀 The inline diesel fuel injection system has a unique structure with an injection pump and nozzle that work together to provide fuel under high pressure.
• 😀 The fuel tank stores the diesel or biodiesel and is one of the primary components of the inline system.
• 😀 The feed pump ensures that fuel flows from the tank to the system, working under a pressure range of 1.8 to 2.2 kg per square centimeter.
• 😀 The priming pump is designed to remove air bubbles trapped in the fuel system, ensuring efficient fuel flow.
• 😀 The fuel filter and water sedimenter remove dirt and water from the fuel to prevent engine damage and ensure proper fuel quality.
• 😀 The injection pump assembly creates high-pressure fuel to be distributed to the injectors, typically at around 110 kg per square centimeter.
• 😀 Delivery valves are responsible for controlling the high-pressure fuel flow from the injection pump to the injectors.
• 😀 The injection nozzle sprays fuel into the combustion chamber in varying amounts based on engine speed, optimizing fuel combustion.
• 😀 The plunger spring inside the injection pump is essential for returning the plunger to its initial position, contributing to the pump's smooth operation.
• 😀 The governor mechanism controls the engine speed by adjusting fuel flow based on the throttle position, using centrifugal force to regulate the movement.
• 😀 Components like the flyweight, tension lever, and control lever work together to adjust fuel delivery according to engine speed, ensuring optimal performance.

Q & A

What is the function of the inline injection pump in a diesel fuel system?

The inline injection pump is responsible for pumping fuel at high pressure to the injectors, ensuring the proper delivery of fuel to the engine's combustion chamber.

What does the 'Feed Pump' do in a diesel fuel system?

The feed pump moves fuel from the tank to the fuel system, maintaining a pressure range of 1.8 to 2.2 kg per cm².

What is the purpose of the 'Priming Pump' in a diesel engine fuel system?

The priming pump is used to remove air bubbles from the fuel line by pressing it repeatedly, ensuring there is no air trapped in the system.

How does the 'Water Sedimenter' work in the diesel fuel system?

The water sedimenter filters out water from the fuel. Since water is denser than diesel, it settles at the bottom, while the fuel passes through clean and free of water.

What is the role of the 'Injection Pump Assembly' in the diesel system?

The injection pump assembly pressurizes the fuel to around 110 kg per cm², directing the high-pressure fuel to the injectors.

What is the function of the 'Delivery Valve' in the diesel injection system?

The delivery valve regulates the flow of high-pressure fuel from the injection pump to the injectors, ensuring controlled fuel delivery.

How do 'Injection Nozzles' function in the diesel engine?

The injection nozzles spray fuel into the combustion chamber. The amount of fuel sprayed is adjusted based on the engine's RPM, with more fuel being sprayed at higher RPM.

What is the role of the 'Governor' in the diesel injection pump?

The governor controls the engine's speed by adjusting the amount of fuel injected based on the speed of the engine, ensuring optimal performance.

What is the significance of the 'Flyweight' mechanism in the diesel pump?

The flyweight mechanism uses centrifugal force to adjust the governor, ensuring that as the engine speed increases, the governor adjusts fuel delivery to match.

What is the function of the 'Plunger Spring' in the diesel pump?

The plunger spring returns the plunger to its original position after it has moved to inject fuel, ensuring proper fuel management and flow in the system.
