- Key functions & working principle
| Working Principle | 1. Fuel Intake: Low-pressure fuel from the fuel tank (supplied by a lift pump) enters the injection pump’s housing, filling the space around the plunger/barrel assembly. |
| 2. Pressure Generation: The engine’s camshaft drives the pump’s camshaft, pushing the plunger upward. This compresses the fuel in the plunger chamber, raising pressure to 180–220 MPa. |
| 3. Fuel Metering: The plunger’s helical groove controls the amount of fuel delivered – rotating the plunger (via the governor) adjusts the fuel volume for different engine loads/speeds. |
| 4. Injection Timing: The delivery valve opens at peak pressure, sending metered fuel through high-pressure lines to the engine’s fuel injectors, which spray fuel into the combustion chambers. |
| 5. Governor Regulation: As engine speed changes, the centrifugal flyweights in the governor adjust the plunger position to maintain consistent speed (e.g., reduce fuel delivery at high speed to prevent overspeeding). |
| Core Functions | 1. High-Pressure Fuel Delivery: Supplies atomized diesel fuel to engine cylinders at the correct pressure for efficient combustion |
| 2. Fuel Metering: Precisely controls fuel volume per cylinder to match engine load (idle, partial load, full load) – optimizes power and fuel efficiency |
| 3. Injection Timing Control: Ensures fuel is injected at the optimal piston position (top dead center) to maximize power and minimize emissions (NOx, particulate matter) |
| 4. Speed Regulation: Prevents engine overspeeding (via governor) and maintains stable idle – protects engine components from damage |
