SEQUENTIAL INGECTION SYSTEM LPG: ENGINE KIT

The "phased sequential" system is the last generation of injection LPG and CNG systems suitable for installation both in multipoint injection sequential vehicles and in multipoint injection "semi-sequential" and "full-group" vehicles.
It is the most effective system that ensures the best results in terms of driving conditions and performance.
The enriching strategies and consumption and emissions optimisation strategies generated by the petrol CPU are indeed unaltered in each cylinder.
This system is compatible with the originaI OBD system (On Board Diagnosis) of the vehicle. The OBD system informs the user if any of the vehicle components dedicated to reducing pollutant emissions may compromise the actual emissions. If this should occur I the user would be informed via a buzzer built-in the change-over switch and the installer can easily find the problem by connecting the system to dedicated instruments.

DESCRIPTION OF THE LPG SEQUENTIAL KIT

LPG in its liquid state reaches the regulator-vaporiser ( 1 ) through the LPG solenoid valve ( 2 ) fitted on the regulator-vaporiser, which is only open when the vehicle is running on gas. The LPG is vaporised inside the regulator-vaporiser and its pressure is reduced. From the regulatorvaporiser the LPG in its gaseous state reaches the rail of injectors ( 3 ) at a positive pressure compared to the vacuum inside the in-take manifolds. The top chamber of the regulator I inside which a calibration spring is fitted, is connected by a tube to the in-take manifold.
There are gauged nozzles on the rail of injectors which are connected to the nozzles ( 4 ) of the in-take manifold by rubber hoses, which inject gas into the engine.
The Sequential system for LPG is a specific one for catalyst vehicles and therefore has an ECU ( 5 ) that commands the gas electro-injectors in the rail, guaranteeing the perfect stoichiometric ratio of the mix by processing the signal of the pressure sensor ( 6 ) and the injection timing of the petrol injectors. When the vehicle is running on gas, the switch-over to petrol is intercepted by an electronic device (emulator) built-in the actual ECU, which cuts-out the original petrol electro-injectors.
The user can choose which fuel to use (LPG or PETROL) using the change-over switch ( 7 ) fitted in a handy position inside the vehicle compartment. The change-over switch comes complete with fuel indicator .
