single hole 
14.5 ohms

This IWP023 “Pico" top feed injector is a production component with a single hole ‘cone’ spray pattern and a wide range of applications for engines typically for small engines up to 25bhp per cylinder (depending on injection pressure)

The characteristics of the injector are a fast pulse response, high precision, high dynamic range and optimum fuel atomisation. These are achieved by a high performance ON-OFF actuating electromagnet with opposing expansion poles that moves an internal injector valve on high-precision ground cylindrical slides, and a high precision nozzle.

The injector has a stainless steel body, a fuel-resistant plastic connector, martensitic stainless steel internal valve and an electromagnet with a low carbon content stainless steel armature.

The electrical connection to the control unit is via a Mini-Timer plastic plug.
