1.4. Selection of pressure regulator.
Connection of wiring should be performed according to the connection diagram (Fig.1).
During connection of the VECTOR sequence gas injection system pay special attention to proper
selection of a pressure regulator for given engine power and injectors’ nozzles. Improper selection
of the pressure regulator in relation to engine power will cause that when the LPG delivery is high
(i.e. the throttle fully opened) the pressure regulator will be not able to ensure nominal LPG
pressure and the pressure in the system will drop. If the LPG pressure will drop below the minimum
value set at the controller the system will switch over to supply with gasoline.
1.5. Selection of injectors’ nozzles
Selection of injectors’ nozzles depends also on the engine power. The injectors’ nozzles
should be selected in such way so that at high engine load and high rpm the multiplier for given
injection time should be close to 1. Most engines have injection times amounting to ca. 15 [ms].
The table below contains list of nozzle diameters depending on power for 1 cylinder. To read out
the nozzle diameter for given engine correctly it is necessary to divide the engine power by number
of cylinders.
