ELECTRONIC CONTROL UNIT “ELIOS” Elios is from the latest generation of electronic control units capable of producing phased sequential injection in the gaseous phase. Unlike what usually occurs in older systems, Elios works in perfect symbiosis with the control unit of the original petrol powered plant, processing all the signals needed to determine the appropriate amount of LPG to send to the engine. It incorporates emulators for the petrol injectors and independently manages the change to gas after commutation (in accordance with the operation temperature), the transitory phases and the diagnosis strategies: enrichment under full load, fuel dropping out (cut-off), restriction of peak rpm, and change to petrol in case of malfunction.
COMMUTATOR Essential and modern design, along with extremely compact dimensions which facilitate installation inside the car. The commutator is an electronic device that permits the changeover between the two existing fuel supply systems installed in the car, by means of an appropriate selector. The change to gas always depends on the engine temperature; Elios electronic control unit is the device which directs this operation. It also has the further function of indicating the level of LPG in the gas tank, by progressive lighting of 5 leds.
ELECTROVALVE Shut-off solenoid valve 12V, with filter, female inlet threads M10x1. Outlet threads male/female M10x1. Dedicated fitting application directly on the reducer/vaporizer. Can be fitted in any position. Filter can be substituted or cleaned without disconnecting the Lpg pipes. Fitting bracket avaiable for connection to Lpg pipes. Max working pressure: - 3Mpa
FILTER The system Polaris includes also an additional filter installed between the reducer and the injector, then operating in gaseous phase, which has the function to protect the sophisticated injectors.
INJECTOR “ATLAS” Atlas is an electronic injector comprising two, three or four nozzles with an appropriate section (varying from car to car depending on cubic capacity), and an electromagnetic ignition coil/valve system that controls the opening and the closing of the nozzles. It features an extremely rapid response (< 1 ms), almost comparable to normal petrol injectors. Because of this, POLARIS also allows for comfortable and optimal driving in every gear.
REDUCER VAPORIZER “Hercules” Hercules is a mono-phase reducer, equipped with water heat exchanger, exit pressure compensation device and temperature and pressure sensors. Compensation permits the pressure change (~ 1.2 bar) between the reducer exit gas and the suction manifold to be maintained at a constant level, in accordance with variations in operating conditions. This involves an increase of the injection pressure in proportion with the engine load, guaranteeing an optimal result from the system for all power requirements. The purpose of the temperature and sensor pressures is to collect the main information regarding the physical state of the LPG and to transmit it to the control unit which then makes appropriate modifications to the injection times.
