Fuel Injector Overview

Product Overview

The fuel injector is a critical component in the engine’s fuel system, designed to deliver precisely metered amounts of fuel into the combustion chamber. This hydraulically operated injector features a closed-end design, ensuring efficient combustion and optimal engine performance. Each injector aligns in the cylinder head, corresponding to one injector per cylinder.

Key Features

• Closed-End Design: The injector valve does not project through the injector tip, providing a differential pressure system.
• Injector Body: Houses all components in precise alignment within the cylinder head, featuring a Teflon coating to prevent sticking.
• Injector Valve: Regulates fuel flow from the injector to ensure efficient engine operation.
• Valve Guide: Supports and directs valve movement, maintaining precise operation.
• Opening Pressure Control Spring: Determines the necessary fuel pressure to elevate the valve from its seat.
• Pressure Adjusting Screw: Compresses the control spring to sustain predetermined pressure levels.
• Lift Adjusting Screw: Manages the valve’s travel distance for optimal function.
• Injector Tip: Houses the valve seat with four spray orifices, directing fuel efficiently into the chamber.
• Carbon Seal: Prevents carbon buildup in cylinder head openings.
• Compression Seal: A nylon seal under the inlet fitting, preventing compression leaks.

Benefits

• Ensures complete combustion for efficient engine performance.
• Provides precise fuel metering for each cylinder.
• Enhances fuel delivery with a defined spray pattern.

Usage Recommendations

• Installation: Do not mix or interchange valve and body components when disassembling injectors. Replace the entire assembly if needed.
• Maintenance: Regularly check injector components for proper alignment and function to maximize engine efficiency.

IMPORTANT: The injector body and valve are a matched pair and must be serviced as a complete unit to maintain precise fuel metering.
