Delphi Diesel Pencil Fuel Injector Nozzle

The Delphi Diesel Pencil Fuel Injector Nozzle (also called a diesel injector nozzle or pencil nozzle) is a precision-made component that atomizes diesel fuel and delivers it into the combustion chamber. Delphi, a long-time original equipment supplier of diesel fuel injection systems, engineers these nozzles to help the engine run smoothly and efficiently.

Key Features:

• Pencil-style nozzle design that sprays fuel in a controlled, finely atomized pattern
• Precision-machined nozzle components made to tight tolerances for consistent injection performance
• Supports efficient combustion, smooth idle, and reliable cold starts
• Helps maintain fuel economy and keep emissions in check when replacing worn or fouled nozzles
• Built for the high pressures and heat of diesel engine operation

A worn or clogged injector nozzle can cause rough running, hard starting, excess smoke, and lost power. Replacing it with a Delphi nozzle helps restore proper spray pattern and engine performance. Each variant in this product line follows Delphi's quality standards for diesel fuel system components.
