1 LPG Filling valve:
fuel nozzle attaching system fitted with a device
through which the tank is filled.
2 LPG Tank:
tank for LPG in its liquid and gaseous phase.
3 Multivalve:
allows gas into and out of the tank, measures level of gas in
the tank and includes various safety devices.
4 Reducer:
device through which the gas changes from the liquid to
gaseous phase thus reducing its pressure.
5 Filter:
filters impurities from gas. Gas and engine load sensors can be built
into the filter itself or put in a separate unit.
6 Gas injectors:
inject the correct amount of LPG into each cylinder.
7 Changeover Switch:
allows user to switch from petrol to gas and vice
versa and indicates level of gas in the tank.
8 Gas ECU:
receives signals from various sensors and calculates the amount
of gas to be injected.

1 CNG Filling valve:
fuel nozzle attaching system fitted with a device
through which the cylinder is filled.
2 CNG Tank:
tank for CNG in compressed gaseous state.
3 Tank Valve:
allows CNG into and out of the tank.
4 Reducer:
reduces to working pressure.
5 Filter:
filters impurities from gas. Gas and engine load sensors can be built
into the filter itself or put in a separate unit.
6 Gas injectors:
inject the correct amount of CNG into each cylinder.
7 Changeover Switch:
allows user to change between CNG and petrol
and indicates level of CNG in the tank.
8 Gas ECU:
receives signals from various sensors and calculates the
amount of CNG to be injected.
