Components fitted to a vehicle
Converting your car to take
advantage of the various benefits of LPG requires the
installation of a small range of components to the
existing vehicle hardware.
The new hardware, which is
highlighted in the above image is minimally invasive
to existing systems and components. This results in
all normal vehicle and engine functions remaining
unaffected after having an LPG conversion fitted.
The ECU
The Electronic Control Unit
processes signals it receives from sensors mounted on
the engine. This information is used to optimise
fuelling, emissions and driveability.
The ECU also has On Board
Diagnostics (OBD) capabilities the same system car
manufacturers use in fact. This monitors the LPG
system and undertakes relevant remedial action in the
unlikely event of system or component failure.
The LPG Tank
LPG is stored, under pressure, in
an LPGA approved tank. Tanks are available in a wide
range of sizes, in either a toroidal (torpedo) or
cylindrical configuration. This enables a wide range
of applications to be accommodated.
To avoid losing boot space, the
toroidal system is commonly installed in the spare
wheel well.
The Vaporiser / Regulator
This is a compensated, two-stage
diaphragm-type regulator/ vaporiser. It incorporates a
water-gas heat exchanger, an internal safety valve and
a gas solenoid valve with in-built filter.
Effectively, it takes the liquid
from the LPG tank and turns it into a gas whilst
controlling the gas pressure.
The Injector Rail
The pressure and temperature of
the LPG is monitored within the injector rail. From
here, the LPG is delivered to the intake manifold via
a series of injectors, which are controlled by the
ECU.
The number of injectors used
corresponds to the number of engine cylinders and
their configuration. This gives the best possible
response and the best fuel economy.
The Switch
This component serves three
purposes:
1. It provides the driver with the
ability to switch from gasoline to LPG and vice versa.
2. The quantity of LPG fuel in the tank is indicated
by a combination of LEDs.
3. A buzzer will sound in the advent of a diagnostic
failure and automatically switch back to petrol.
