摘要

Digital Electronic switch for CNG vehicles, which comprises the control of fuel supply system of Engine, through which it is possible to realize the switching between different Fuels at the same time, It presents the related information and the CNG pressure L state of Valves.The main purpose is to provide a Switch device which facilitates the user reading the information related to the State of the System, in particular the CNG pressure, at present the same through a Viewfinder.At the same time allows the device to perform the control of fuel supply to the engine in the Boot, as in regime, and as new feature includes the calculation of Self, which is also presented through the viewfinder. It includes an audible Alarm with which the user is warned that the fuel has reached a configurable Threshold.It also provides the engine speed, Vehicle Speed and the type of fuel being used. An additional feature is a Security Key with which it is possible to block the supply of fuel to the engine serving as Prevention against the possibility of theft.In an Engine equipped with electronic injection comprises: a Control Unit (1), which comprises a microcontador, a group of Sensors or Transducers, Signal input, which generally includes a Pressure sensor, a sensor (2) CNG engine speed (3), and a Sen Sr. of Distance traveled by the vehicle (odometer) (4), a keyboard (5),A Display (6) and an audible Alarm (8), which represent the user interface; and the control of the fuel valve (7), which Act in General on the flow of CNG and Gasoline.
