The Fuel Injection Equipment Test Stand Nozzle Lines manage the controlled return of nozzle bleed flow during fuel injection testing to maintain stable test conditions and fluid balance. The lines allow excess fuel released during nozzle operation to move away without pressure buildup, supporting accurate observation of injection behavior. By directing bleed flow back to the test oil sump, the lines help maintain a clean and controlled testing environment while preventing overflow and fluid loss.Attributes:• Helps maintain steady flow conditions throughout testing.• Supports stable pressure conditions during nozzle testing.• Prevents uncontrolled fuel discharge during test cycles.Applications: The Fuel Injection Equipment Test Stand Nozzle Lines are used within the fuel injection testing setup, where nozzle return flow is managed and guides nozzle-bleed fuel away from the test point and back to the test oil sump.
