ТРУБКА Caterpillar 1397936

The Fuel Injector Leak Off Tube manages surplus fuel from the injectors and redirects it to the fuel return system for reuse. Helps maintain steady fuel pressure, prevents overloading of the injector, and supports consistent combustion performance. By removing excess fuel, it also reduces the risk of injector flooding and ensures cleaner engine operation. The tube works continuously during engine cycles, managing fuel flow without interruptions.Attributes:• Maintains optimal injector cooling through constant fuel flow.• Limits fuel temperature rise inside injectors during prolonged operation.• Contributes to uniform injector spray patterns by regulating fuel volume.Applications: The Fuel Injector Leak Off Tube directs surplus fuel from each injector to the return system, maintaining stable fuel pressure and enhancing combustion consistency during engine operation.
