WG972-E4, WSM
[7] REGULATOR WITH VAPORIZER (GAS LINE)
[WG972-GL, WG972-L, WG972-N]
Regulator with vaporizer evaporates the liquid fuel
(LPG / CNG) into the gaseous fuel and then sends to the
mixer. Regulator with vaporizer has the following
structures and functions.
 Evaporator
Evaporator has a long fuel passage to evaporate
liquid fuel to gaseous fuel.
 Hot Water Line
The coolant water of the engine is made to circulate
as a heat source to prevent freezing of vaporizer by
latent heat of vaporization.
 Primary Stage
There is a primary valve which is safety device for
abnormal pressure.
 Secondary Stage
Secondary stage has a secondary valve and controls
the quantity of gaseous fuel flowing to the mixer.
