These diesel fuel injection pumps, identified by part numbers 326 - 4635 and 320 - 2512, are specifically engineered for use in the Caterpillar Excavator E320D equipped with the C6.4 engine. They are crucial components of the engine's fuel delivery system, ensuring precise and efficient fuel injection for optimal engine performance.
Performance Parameters
Injection Pressure
Minimum Injection Pressure: The pumps are designed to generate a minimum injection pressure of [X] bar. This pressure is essential for initiating the fuel injection process and ensuring proper atomization of the diesel fuel in the engine's combustion chambers.
Maximum Injection Pressure: Under high - load conditions, the pumps can reach a maximum injection pressure of [Y] bar. This high - pressure capability allows for efficient fuel combustion, delivering the necessary power output for the excavator's operations.
Flow Rate
Rated Flow Rate: At the engine's rated speed of [Rated Speed] RPM, the combined flow rate of the fuel injection pumps is [Z] liters per minute (L/min). This flow rate is calibrated to meet the fuel requirements of the C6.4 engine under normal operating conditions.
Peak Flow Rate: During peak power demands, such as when the excavator is performing heavy - duty tasks, the pumps can provide a peak flow rate of [Peak Z] L/min to ensure continuous and reliable engine operation.
