MIU injection system
This vehicle is fitted with an integrated injection and ignition system.
Injection is indirect in the manifold through an electro-injector.
The injection and ignition are timed on the four-stroke cycle by means of a tone wheel keyed on to the
crankshaft (24-2 teeth) and pick-up sensor.
Combustion and ignition are managed on the basis of engine revs and throttle valve opening. Further
corrections are made according to the following parameters:
- Coolant temperature.
- Intake air temperature
- Lambda probe
The system implements an idle feeding correction with cold engine through a Stepper motor on a by-
pass circuit of the throttle valve. The control unit manages the Stepper motor and the injector opening
time, thereby ensuring the idle steadiness and the proper combustion.
In all conditions of use, mixture preparation is managed by modifying the injector opening time.
The fuel system pressure is kept constant based on the ambient pressure.
The
fuel system circuit
consists of:
- Fuel pump
- Fuel filter
- Injector
- Pressure regulator
The pump, the filter and the regulator are placed inside the fuel tank on a single support.
The injector is connected by a pipe with fast-release fittings. The pressure regulator is located at the
beginning of the circuit.
The fuel pump is controlled by the MIU control unit; this ensures the scooter safety
The
ignition circuit
consists of:
- HV coil
- HV cable
- Shielded cap
- MIU control unit
