A precision component of the injection system – an injector nozzle designed for turbocharged Perkins engines (AK, AQ series) with 100 HP, fitted in machines from 2001-2005. As the final element of the fuel system, it is responsible for the perfect atomization of the diesel fuel dose in the combustion chamber. Proper fuel atomization is crucial for full power, low fuel consumption, and trouble-free engine starting. A damaged nozzle causes "dribbling" of fuel, which leads to a loss of power, smoke, and can result in piston damage.
GX-AFTER is the smart choice for your machine. We provide high-class replacement parts that combine excellent quality with an attractive price. Each part is carefully verified to ensure full compatibility and reliability you can depend on.

The list above is for reference. It is key to match the nozzle to the injector number and specific engine model.
The injector nozzle is critical for proper combustion. Its wear or damage leads to a deterioration in engine performance, and in extreme cases, to serious engine failure (e.g., a hole burned in a piston).
A "dribbling" injector is a direct path to engine destruction.
The cost of replacing injector nozzles is negligible compared to an engine overhaul caused by a hole burned in a piston. Don't take risks – order high-quality GX-AFTER nozzles and restore your engine to its factory parameters, smooth operation, and low fuel consumption.

A "dribbling" injector means that instead of atomizing the fuel into a fine mist, it delivers it in a stream or large droplets. This situation leads to incomplete combustion, smoke, loss of power, and can lead to a hole being burned in the top of the piston.
2. Do I need to adjust the injection pump after replacing the nozzles?No, replacing the nozzles themselves does not require adjustment of the injection pump. However, it is necessary to adjust the opening pressure on each reconditioned injector to match the specification for the given engine.
3. How does a nozzle for a turbo engine (AK) differ from one for a naturally aspirated engine (AR)?Nozzles for turbocharged engines are designed to work with higher injection pressure and a larger fuel dose. They have a different number, diameter, or angle of spray holes to ensure optimal combustion in conditions with more air supplied by the turbocharger. Using the wrong type of nozzle is not permissible.
