GASOLINE / LPG ENGINE
[6] RADIATOR CAP
The pressure type radiator cap prevents differences
in pressure between the inside and the outside of the
radiator from deforming the radiator.
When the coolant temperature rises and the pressure
in the radiator increases above the specified pressure,
the pressure valve (1) opens to reduce the internal
pressure.
When the coolant temperature falls and a vacuum
forms in the radiator, the vacuum valve (2) opens to
introduce the air into the radiator.
[7] VAPORIZER (DF972-E2)
When evaporating by primary chamber of vaporizer
liquid LPG needs the evaporation heat.
This vaporizer installs the water jacket, throws the
coolant of engine, heats primary chamber, promotes
evaporation, and prevents valves being frozen.
