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
6 R O H Q R L G Y D O Y H Tumble rpm Torque TH2O
Off On 0÷2000 rpm < 40% < 60°C
Off On 0÷3000 rpm < 40% > 60°C
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.
