The Wacker Neuson Injection Nozzle is a genuine OEM component designed for the G40, G50, G60, G70, G95, and G110 series portable generators. Sourced directly from Wacker Neuson, this part meets the original engineering specifications required to maintain proper fuel atomization and combustion efficiency in your generator. It is a direct-fit replacement for a wide range of GP-family models across standard, mobile, and LATAM-market configurations. If your generator is running rough, struggling to reach rated output, or showing signs of fuel delivery issues, replacing the injection nozzle with a genuine OEM part like the is the correct first step.
Key Features
- OEM Fuel Atomization Spec: — Calibrated to the exact spray pattern and flow rate required by Wacker Neuson G-series diesel generators for clean, consistent combustion.
- Drop-In Fitment: — Engineered to seat and seal in the original nozzle bore without any modification to the fuel injection system.
- Broad G-Series Compatibility: — Confirmed fitment across G40, G50, G60, G70, G95, and G110 generator models, including mobile, standard, and LATAM Premium variants.
- Sustained Power Output: — A correctly functioning injection nozzle keeps fuel delivery consistent, supporting stable voltage and load capacity at rated output.
- Fuel System Integrity: — A worn or fouled nozzle can cause hard starting, black smoke, and excessive fuel consumption; replacing with a genuine OEM part restores proper system calibration.
The injection nozzle is responsible for delivering a precisely metered and atomized spray of diesel fuel into the combustion chamber at the correct pressure and angle. On Wacker Neuson G-series portable generators, accurate fuel atomization is critical to achieving the clean burn needed to maintain stable electrical output and meet emissions requirements. When a nozzle wears, becomes clogged, or begins to dribble rather than atomize, combustion quality deteriorates — leading to hard starts, rough running, increased fuel consumption, and potential long-term damage to the engine.
