Blitz and Just Systems


With the coming of catalytic injection vehicles, BRC started to project and trade a line of carburetion control systems for the installation on vehicles manufactured according to the anti-polluting norms (from Euro 1, in Italy since 1/1/1992). So a catalytic vehicle, in order to be converted to LPG or CNG, needs a device that could acquire and elaborate the Lambda oxygen sensor signal. This device has also the task to always obtain a perfect air/gas mixture and to manage the automatic changeover from petrol to gas.


Blitz system acts in “closed loop”, correcting in real time the air/gas mixture title according to the information coming from the Lambda oxygen sensor. As known, this sensor creates a tension signal depending on the oxygen present in the exhaust gases so that it supplies an indirect measure of mix title (poor, stoichiometric and rich).This allows the ECU to act on the actuator checking the gas flow through a suitable power stage. Blitz was exclusively conceived to only manage the actuator patented for this system so that it is not compatible at all with other types of actuators.
Besides, Blitz system manages different functions such: changeover, safety, level indication, Lambda oxygen sensor signal emulation. The function of injectors interruption and emulation can be managed by an eventual external emulator. Blitz ECU can be connected to the Diagnostic Box device which allows the system set-up and possible diagnosis through suitable bar led, Blitz system is available in different versions recognisable for the presence or absence of the functions described above.


Just system is different from the Blitz one for having an actuator equipped with step motor for the control of the gas flow, which takes the place of the classic actuator and of the adjusting screw. Moreover, it has a digital electronic ECU. ECU bases itself on a digital hardware, which use a microcontroller architecture that allows a big flexibility in the management of the input coming from the different engine sensors and a successful management of the gas installation output.
Just system was exclusively conceived to manage “Step” actuator.It consists of a step by step starter that with its movement put upright a pivot that closes the gas passage towards the mixer. The actuator movement is controlled by the engine control strategy according to the different inlet sensors. The digital system decides very quickly, so that actuator movement can guarantee a constant keeping of the correct stoichiometric ratio. Moreover, Just manages different functions such: changeover, safety, level indication, Lambda oxygen sensor signal emulation.
Interruption and emulation functions of the injectors can be managed by an eventual external emulator. This device set-up can be made both by the changeover switch and the Diagnostic Box BRC tool, and by a PC equipped with a programming and interface software.


Sistema Blitz e Just GPL
Il GPL allo stato liquido, tramite la presa di carica, raggiunge il serbatoio. Di qui grazie alle importanti funzioni svolte dalla multivalvola, per mezzo della tubazione ad alta pressione e comandato dall'elettrovalvola GPL, raggiunge il riduttore-vaporizzatore di tipo elettroassistito. Qui, grazie all'acqua derivata dall'impianto di raffreddamento del motore, passa allo stato gassoso e alla pressione atmosferica e successivamente raggiunge il miscelatore, al fine di essere opportunamente miscelato e dosato con l'aria. In luogo di una semplice centralina di commutazione è necessario, sia da un punto di vista funzionale sia da un punto di vista normativo, l’impiego di un sistema di controllo della carburazione composto da centralina di controllo e attuatore di flusso (Step Motor su Just). Questi due componenti, per poter essere installati, devono essere sottoposti dal costruttore dell’impianto ad omologazione, in riferimento alla direttiva antinquinamento in vigore.
Per la trasformazione della parte “anteriore del veicolo” sono quindi disponibili specifici kit composti da un riduttore Elettro-assistito, da una attuatore (o Step) per il controllo della portata di gas, da un miscelatore e da una centralina elettronica.
