Fig. 1.35. Fuel injector: 1 - electrical connector; 2 - sealing ring; 3 - retaining ring, fixing the upper sealing ring; 4 - mesh filter; 5 - metal body; 6 - solenoid coil
The F3R engines are equipped with fuel injectors of the type "Siemens Deka 2" and are mounted on the fuel distribution line. The sealing of each injector is carried out by two sealing rings. Fuel constantly circulates inside the injector body. Such constant movement of fuel prevents the formation of vapor locks and facilitates starting a hot engine.
- Removal the injectors is not difficult, but first you need to remove the fuel distribution line, since the fuel in it can get into the engine cylinders.
- To install the upper O-ring, use the conical mandrel supplied with the O-rings.
