FOTON AUMAN GTL TRUCK Cummins ENGINE High Pressure Fuel Injection Pump 4327065
FUNCTION
1. Generate Ultra-High Fuel Pressure: Pressurizes low-pressure fuel to a maximum exceeding 2000 bar, providing a stable, high-pressure fuel source for the common rail and injectors.
2. Precisely Control Fuel Supply: Based on ECU commands, utilizes built-in metering units and pressure control valves to regulate fuel flow and pressure in real-time, thereby enabling on-demand fuel delivery.
3. Support Multiple Injection Events: Facilitates various engine functions-including main injection, pre-injection, and post-injection-to optimize combustion efficiency and reduce fuel consumption and emissions.
4. Maintain System Pressure: Sustains stable high pressure within the common rail across a wide range of operating conditions (such as idling, high load, and acceleration), ensuring precise fuel injection by the injectors.
Installation Location
Mounted directly on the gear cover located at the front of the engine, and driven directly by the engine's camshaft or gear train.
Working Principle
1. The pump body is driven by the engine's camshaft or gears.
2. Upon entering, the low-pressure fuel is subjected to intense compression through the reciprocating motion of the plunger.
3. The Electronic Control Unit (ECU) controls the metering valve and overflow valve via PWM signals to achieve closed-loop pressure control.
4. The high-pressure fuel is delivered to the common rail, where it is then distributed to the injectors for each cylinder.
Advantages
| No. | Performance Advantage | Detailed Description | Actual Benefits |
|---|---|---|---|
| 1 | Ultra-High Pressure Precise Fuel Delivery | Maximum working pressure up to 2000+ bar, supports multiple injections (pre-injection, main injection, post-injection) | Finer fuel atomization, more complete combustion |
| 2 | Improved Fuel Economy | ECU precisely controls fuel flow and injection timing on demand | Fuel consumption reduced by 5-10% (especially noticeable under heavy load and long-distance) |
| 3 | Excellent Emission Performance | Precise combustion control reduces incomplete combustion | Lower PM and NOx emissions, meets National VI / Euro VI standards |
| 4 | High Reliability & Durability | High-temperature sealing + precision plunger + fuel-lubricated design | Low failure rate, longer service life |
| 5 | Fast & Stable Power Response | Quickly builds and maintains stable rail pressure under all operating conditions | Better acceleration response, stronger climbing ability under heavy load |
| 6 | Low Maintenance Cost | Original equipment design with good filtration system, extended maintenance intervals | Reduced repair frequency, lower long-term operating cost |
