    The invention relates to a device for controlling the opening time of the injectors of the vehicle by modulating the input and output current. It consists of a box placed in parallel on the injector beam (2) and having an electrical circuit in which the information flow system is as follows: the information is sent simultaneously to the micro controller (4) by the zener diodes (3), the potentiometer (7), the switch (8) and the temperature sensor (6), then the microcontroller sends information to the transistors (5) and LEDs (9). The invention thus makes it possible to intercept the control signals intended for the injectors by modifying them so as to increase the injection time required in the context of the use of bioethanol. This device according to the invention is particularly intended for the gasoline vehicle with a direct injection engine.

    专利说明:

    The present invention relates to a bioethanol conversion system that allows gasoline vehicles to use both unleaded fuel (SP95 and SP98) and bioethanol (E85) in the original tank, without modifying driving pleasure. and maintaining the reliability of the engine. 5 This conversion device is dedicated to the new generation direct injection gasoline engines that equips in France, the majority of vehicles built since 2009. It is the optimization of gasoline engines in the interest of lowering their consumption and reducing fuel consumption. increase their performance which gave birth to this technology of direct injection engines.
    Until now, no manufacturer of bioethanol conversion boxes has been able to equip cars equipped with a new generation gasoline engine of the direct injection type.
    In fact the old ethanol conversion boxes operated for the majority, only on a voltage of 12 volts and acted in series on the ground signal son. The old housing is connected in series to the control wire of the injector (the wire is cut and inserted) The second wire feeding the injector is not a control (power supply of the injector This box 20 simulates the resistance of the injectors to the vehicle computer so that it sends the opening time of the injectors.The injector is supplied with 12 volts by the battery at the input and a simple setting The direct output engines use a pulse of 20 to 100 volts to open the injector and a voltage of 12V to keep the injector open.
    The present invention according to the device makes it possible to control the duration of opening of the injectors insofar as the use of Bioethanol requires the injection of 25% more fuel. At first, the injector opens at high voltage (20 to 120 volts) In a second step, the injector is kept open by a voltage and a lower intensity (0 to 14 volts) The control injectors is therefore achieved by modulating the input and output current of this one
    The box analyzes the signals reaching the injectors and interprets them via its microcontroller.
    The device comprises a connection acting on each of the two son supplying the injector.
    This system is all the more innovative and unique, it manages to change the signal of the injector (acting on its opening time) being connected only in stitching on son supplying it.
    By this method, the device still retains its ability to analyze and then index the current of the injector, without changing the original wiring diagram of the vehicle. Finally, this device is completely efficient insofar as if for any reason, it becomes inactive, the vehicle would recover its original properties of operation with gasoline. The invention thus makes it possible to intercept the control signals intended for the injectors by modifying them so as to increase the injection time as a function of the desired degree of enrichment.
    The device comprises in fact according to a first characteristic, a housing which has an electric circuit with a microcontroller. This controls the transistors which make it possible to control the opening of the injectors between the low voltage of 0 V and the measured voltage of 12 V (in order to increase the injection time as a function of the desired degree of enrichment).
    The housing is placed in parallel on the injector harness, it includes:
    The microcontroller or calculator which is the electrical brain which controls the information of the device, The transistor: switch which makes it possible to control the opening of the injectors, switch: which must be set manually during the installation and which makes it possible to adjust the injection level,
    The potentiometer which makes it possible to adjust the injection level when the motor starts cold, 25 The temperature probe: which makes it possible to measure the temperature and to diagnose if the injection is done via the potentiometer or the switch,
    Indication LEDs that indicate whether the device is operating in cold mode and indicates the injection rate in hot mode,
    An input for an analog signal is also provided, in order to provide the microcontroller with information on the ethanol fuel dosage contained in the tank of the vehicle.
    The protection diodes that protect the transistors,
    The zener diodes that retrieve the signals from the computer of the car to the micro controller of the device. The accompanying drawings illustrate the invention:
    The figure shows in section, the device. All the parts are connected to the micro controller (4)
    The information flow system in the device is as follows: the information is sent simultaneously to the microcontroller by the zener diodes (3), the potentiometer (7), the switch (8) and the temperature sensor (6). ) the microcontroller (4) sends information to the transistors (5) and leds (9) indication.
    Information sent to the Micro controller:
    The zener diodes [3] send a logic signal which indicates the state of the injector (2).
    The potentiometer (7) returns an analog voltage which makes it possible to measure the cold injection rate. The switch (8) returns a logic voltage which makes it possible to define the hot injection rate.
    The temperature sensor (6) returns an analog voltage which makes it possible to define the outside temperature.
    A sensor external to the device sends an analog voltage via an input to the device to provide information to the microcontroller (4) on the fuel dosage contained in the vehicle tank. The microcontroller (4) then adapts the opening time of the injectors [2] also according to this analog signal.
    Information sent from the microcontroller: The microcontroller (4) sends information to the transistors (5), namely logic signals for opening or closing the injector.
    The microcontroller (4) sends information to the LEDs [9), namely logic signals to indicate the state of the housing, (hot or cold mode at the time of starting the engine).
