control unit. The two throttle cables (opening and closing) actuate on a scroll mounted on a shaft and

which is sent back to its home position by a return spring.

On the shaft covers there are 2 double track potentiometers (4 control tracks) by means of which the

torque demand is read (and checked).

Marelli 7SM electronic control unit

 Besides the regular control functions of the injection system, it

supervises the throttle bodies: Through the throttle grip position sensor, it reads the torque demand

and, through the TORQUE REQUEST MAP, it decides the throttle opening. It checks the correct op-

eration of each component (Self-diagnosis), of the system (Safety), and carries out the emergency

procedure (Recovery).

Throttle Body

 The two throttle bodies are made up of:

•

Throttle valve with 2 return springs for the controlled minimum opening position.

•

DC electrical motor

•

Tinned double throttle position sensors with magnetic control (contactless)

The throttle bodies do not require any maintenance and cannot be overhauled. In case of electric or

mechanic malfunction, replace the whole unit.

Pressure sensor

 The pressure sensors (one per bank) are fundamental not only for the injection map

at low and stabilised speeds but also for checking the Ride by Wire system: their signal is connected

to a TORQUE CHAIN for checking the correct opening of the throttle valves.

Intake air temperature sensor

 The signal coming from the sensor is used to calculate the estimated

torque since the oxygen in the air also depends on its density which varies according to temperature.

Engine temperature sensor

 The signal coming from the sensor is used for the stimation of the me-

chanical effects.

2 - Injection/ignition control

Map for injection type (alpha-D)/n where:

•

alpha is the throttle position

•

D is the pressure measured at intake ducts

•

At idle speed and at low and stabilised speeds, a strategy D/n is used.

•

For throttle medium-half opening, a strategy alpha/n is used

•

For transients (speed change) a strategy alpha/n is used.

•

The main parameters that correct the injection map are:

•

Engine temperature

•

Atmospheric pressure (calculated)

•

Lambda probe signal

•

Air temperature

3 - System safety checks

The checks are structured in several levels:

•

Level 1 - sensor correct operation
