Tumble system
The tumble system is made up of diaphragms commanded according to the characteristic diagram of the engine,
and are used to restrict emissions. The diaphragms are closed (so the valve is disabled) at low speed and low load.There are two operation speeds depending on the water temperature.

cylinder.
The intake manifold diaphragms are opened, releasing the entire section of the duct when power is demanded of
the engine. All diaphragms of a cylinder bank are fastened to a common camshaft.
The position of the intake manifold diaphragms for each cylinder bank is checked by the Hall sensors which, in the
event of incorrect reading, send the information to the ECU that turns on the engine malfunction warning light. This information can be seen using the LaRa-AS .
The intake manifold diaphragms are enabled by a cylinder bank vacuum positioner in the engine for high rotation
speeds. Feedback of the position of the diaphragms is provided in this case as well, through the Hall sensors. In
the case of malfunctioning, they send the information to the ECU. Also in this case the errors can be read using the LaRa-AS .
The system is in stand-by (therefore enabled) with the engine cold, TH2O < 60°C, and with a torque demand
< 40% beneath 2000 rpm.
The system is operating (therefore disabled) with the engine hot, TH2O > 60°C, and with a torque demand < 40%
beneath 3000 rpm. The activation solenoid valve for the vacuum system is underneath the intake manifold: • it is enabled when the intake manifold is closed
• it is disabled when the intake manifold is open

On Off over 2000 rpm > 40% < 60°C
On Off over 3000 rpm > 40% > 60°C
Malfunctioning is detected by the LaRa-AS system and can be caused by a lack of vacuum
(therefore, leakage in the circuit) or in the two position detection sensors.

The anti-evaporation system prevents the fuel vapors, which consist of the lightest fractions of the hydrocarbons that form in the tank, from discharging into the atmosphere and being suctioned again to be burned.
The system operates especially when the outside temperature is high and the fuel temperature rises, thus increasing the tendency to evaporate. 2 S H U D W L Q J 3 U L Q F L S O H

It prevents the fuel from reaching the canister in the case of hard acceleration/deceleration when the car has a
full tank, or from spilling from the tank, in case the car rolls over;
• It allows the vapors to pass from the tank to the canister;
• It enables to discharge into the atmosphere any excess pressure inside the tank (electrovalve malfunctioning,
clogged pipe).
The canister is connected, by means of two solenoid valves, to two pipes that convey the vapors to the engine intake
manifolds. With the engine running, each solenoid valve is piloted in duty-cycle by the engine control unit according
to engine speed and load, thus putting the canister into communication with the intake manifold and allowing the
suction of the vapors inside the canister. At high engine speed, a venting valve, connecting the canister to the
