5801507557 NOZZLE ( GENUINE )

The 5801507557 Fuel Injector Nozzle is a CNH Genuine high-precision component designed for the Case 570 SV and Case 570 ST backhoe loaders.

This nozzle controls the fine atomization and delivery of diesel fuel into the combustion chamber, ensuring efficient burning, strong engine power, lower fuel consumption, and reduced emissions.

A high-quality injector nozzle is essential for proper engine performance, especially for machines operating under heavy-duty or continuous workloads.

Function of the Fuel Injector Nozzle

The injector nozzle is responsible for:

• Atomizing diesel fuel into fine particles

• Ensuring optimal fuel spray pattern

• Delivering fuel at the correct pressure and timing

• Maintaining stable combustion

• Improving engine power and throttle response

• Reducing black smoke and excess fuel burn

A worn or damaged nozzle will cause incomplete combustion and engine performance issues.
