FUEL SYSTEM -- LPG
The liquid withdrawal LPG fuel system has up of
five components: the LPG fuel tank, pressure
relief valve, fuel filter lock, vaporizer-regulator,
and the carburetor.
Liquid LPG fuel flows from the LPG tank under its
own pressure, to the pressure relief valve. Usually
this valve is closed, preventing LPG fuel from
escaping into the atmosphere. The valve opens to
relieve pressure if the fuel pressure exceeds
system limits. From the pressure relief valve, the
liquid LPG fuel flows to the fuel filter lock.
The fuel filter lock filters unwanted tank scale and
deposits out of the LPG fuel. The fuel filter lock
also stops the flow of LPG fuel when the engine is
not operating. The filter fuel lock allows LP fuel to
flow to the carburetor when engine vacuum is
sensed.
The vaporizer section of the vaporizer-regulator
converts the liquid LPG fuel into a gaseous LPG
fuel. From the vaporizer section, the gaseous
LPG fuel is sent to the primary regulator section
of the vaporizer-regulator. The primary regulator
section reduces the pressure of the LPG fuel. The
secondary regulator section reduces the LPG fuel
pressure to the level required by the carburetor.
From the vaporizer-regulator, the LPG fuel is sent
to the carburetor where it is finally metered into
the air flow sent to the engine combustion
chamber.
Never operate an LPG powered machine if the
LPG fuel system is leaking, or if any component in
the fuel system is malfunctioning. Operating the
machine under either of these conditions may
cause a fire or explosion.
Check for frosting. If frosting occurs on or near
any LPG component, there is a possible LPG fuel
leak or malfunctioning component.
