1-11129064-1 SLEEVE NOZZLE HOL For ISUZU ZX450-3 6WG1T

SLEEVE NOZZLE HOLDER plays an important role in automobile fuel injection system. The main function of the injector bushing is to ensure the tightness between the injector and the engine block, prevent the fuel from leaking, and ensure that the fuel can be injected into the engine block accurately and efficiently. In addition, it can also fix the fuel injector to ensure that it will not shift during work. Fuel injector bushings are widely used in all kinds of gasoline and diesel engines, whether it is family cars, commercial vehicles or construction machinery.

‌ The Sleeve Nozzle Holder, also known as the Injector Sleeve or Nozzle Holder Bushing, is designed to support and guide the fuel injector within an engine’s cylinder head. It helps to secure the injector in position, ensuring optimal spray alignment and fuel atomization for efficient combustion. This component also acts as a seal to prevent fuel and combustion gases from leaking, enhancing engine performance and fuel efficiency.

The main function of injector bushing is to ensure the tightness between injector and engine block. It can effectively prevent fuel leakage and ensure that fuel can be injected into the engine cylinder accurately and efficiently. In addition, the injector bushing can also play the role of fixing the injector to ensure that it will not be displaced during work. The working principle of the injector bushing is that the high-pressure oil is delivered to the fuel supply port of the injector through the high-pressure oil pump, and high pressure is generated in the injector body to act on the conical surface of the injector. When the oil pressure exceeds the set value, the valve core of the nozzle opens, and the high-pressure oil is ejected from the nozzle orifice to form a mist, which enters the engine cylinder and burns, making the piston reciprocate.
