Microprocessor valve with housing is installed within the engine space in an inaccessible place in certified garages. In that way executive electronics is integrated into the engine itself in order to provide the best possible protection.
As additional security it is possible to apply electronic blockage of engine in several points.

Such a protected vehicle will be impossible to drive away using its own driving power, without the original key tag or without a complex and time consuming intervention on the engine and the electricity of the vehicle.
