LPG conversions for petrol vehicles : the
lpg conversion process
The
conversion to dual fuel leaves the petrol system of the vehicle
intact. An additional, separate fuel system is added that
uses LPG. Gastech use what are considered to be the best
components available, and offer a range of tank installation
options to suit your specific vehicles requirements. The
main components of a Gastech LPG conversion are listed below.
We are happy to explain the whole conversion process and
the role of each component in more detail should you require.
SWITCH
The Switch is fitted inside the vehicle cabin, and although
Gastech’s LPG Systems are fully automated, this offers
the driver the ability to manually change from LPG to petrol
use, or vice versa.
LPG
TANK
The LPG tank is installed in the most suitable place to
suit your vehicle. Our experience is second to none and
we will
advise on the recommended tank option.

Incorporated
in the LPG tank assemblies are:
Float
complete with a one-way shut-off safety valve, connected
to the inlet pipe from the
LPG filler;
Over-pressure
relief valve, controlling the release of pressure in a safe
and regulated manner in the
case of
overfill or
fire;
Gauge
sender, utilising float information to give tank level reading;
and Lock-off safety valve, located on the outlet feed
to the engine, which is electrically operated.
LPG
FILLER
The LPG filler is of the recommended recessed
bayonet type, and incorporates a one-way shut-off
safety
valve.
VAPORISER
The Vaporiser is heated by engine coolant,
and receives LPG in liquid form from the
tank. It
reduces pressure
to a controlled
working level. It also incorporates measurement
of the LPG temperature and pressure, allowing
the LPG
computer
to modify
fuelling characteristics. A Vaporiser lock-off
safety valve is located on the inlet feed
from the tank,
and is electrically
operated.
LPG
INJECTORS
Modern petrol engines have one dedicated
petrol injector for each cylinder. Gastech
leave the
original petrol
injector intact
and add an additional dedicated LPG injector
for each cylinder, to ensure correct
fuel distribution and maximum
efficiency.
The
LPG injectors are computer-controlled, allowing the appropriate
amount of LPG
to enter the engines
inlet
manifold at the
correct time.
LPG
COMPUTER (ECU)
The LPG computer (Electronic Control
Unit) controls the LPG system, and
is specifically
developed
to ensure maximum
efficiency,
and full OBD compatibility.
