Operation
The linear electrical engine (1.06) has the basic function of regulating the number of engine rotations. It is controlled by the GBL module, only in vehicles with the ASR system.
The electro pneumatic valve (33.01), when activated, allows the passage of air that comes from the 4-circuit protective valve (4.03) to the pneumatic cylinder of the injector pump lever stop (20.05).
The pneumatic cylinder of the injector pump lever stop (20.05) has the function of avoiding that the linear electrical engine strangles the injector pump lever too much, causing it to stop the engine.
