Excavator Spare Parts Fuel Controller J170-96B-020000 60070-96-00019

The excavator spare part fuel controller is the core component that regulates engine fuel supply, optimizing power output and fuel efficiency by precisely controlling injection volume and pressure. The fuel control center receives commands from the ECU to adjust fuel pressure and flow, ensuring stable engine operation under various operating conditions. It utilizes a differential pressure control principle: when intake manifold pressure fluctuates, the diaphragm-actuated oil return valve dynamically adjusts the oil pressure to maintain a constant injection pressure differential. The integrated control type (mechanical hydraulic): Fuel flow is regulated through components such as the oil distribution valve and metering valve, making it suitable for older models.
