Втулка форсунки головки блока цилиндров двигателя Caterpillar 521-2977

An Engine Cylinder Head Injector Sleeve fits inside the cylinder head to create a secure seating area for the fuel injector. It forms a sealed passage between the injector and the cylinder head, helping direct fuel accurately into the combustion chamber. It prevents fuel, combustion gases, and coolant from leaking into surrounding areas, maintaining proper separation between internal passages. It supports correct injector alignment, which helps ensure proper fuel spray patterns and efficient combustion.Attributes:• Reduces risk of compression loss around the injector area.• Helps prevent contamination of engine fluids.• Supports consistent engine starting and performance.Applications: An Engine Cylinder Head Injector Sleeve is located inside the cylinder head where the fuel injector is installed, and it seals and positions the injector to direct fuel into the combustion chamber while preventing leakage of fuel, gases, and coolant.
