INJECTION FUEL FEEDING SYSTEM (TC)
The injection fuel feeding system is composed of fuel tank (1), electric pump
(2), pipe (3) and injector (4). The fuel in the tank is pumped by the pump. The
pressurised fuel flows into the injector installed on the throttle body (6). The
electronic control unit (5) located under the tank signals the injector to open and
a fan-shaped spray of fuel is injected into the combustion chamber.
The parameters that play a role in determining proper fuel delivery under all
operating conditions are as follows:
- Air temperature in the intake manifold;
- Engine coolant temperature;
- Atmospheric pressure in the intake manifold (in current location and at cur-
rent altitude);
- Throttle opening;
- Gear shift position;
- Fuel injection pulse width;
The "HUSQVARNA SERVICE TOOL" provides a tool to check these parameters
in the event the fuel injection malfunctions.
The electric fuel pump (2) is installed on the bottom of the tank (1) and is com-
posed of rotor, magnet, impeller, brushes, control valve and relief valve. The
electronic control unit (5) switches the pump ON/OFF.
To remove the fuel pump (2) see section “E”.
