What is Diesel /LPG
The diesel LPG gas system allows a small amount
of LPG to be placed into the engine via the air intake system. The
lpg gas acts as a catalyst to the combustion process aiding the
burning process of the diesel. Combustion efficiency here is 95-98%
compared to just the diesel of 75-85%.
This is the reason for the Black smoke that is
deposited into the atmosphere. This process is also the reason now
your diesel engine will be much more fuel efficient , more
power and torque and of course cleaner emissions.
These modern systems are now computer controlled
using sensors to determine engine load and speed, with this it can
be programmed now to adjust the amount of LPG for varied
amounts of power and economy. Simple.
And if safety is a concern , technology and
strict standards now produce a very safe system.

The Add-Gas Diesel
Superchips is a state of the art LPG injection system for Diesel engines
that is far superior to anything else on the market. Fully assembled out of
the box and preprogrammed engine specific from the factory this unit is the
smartest injection system to install in the industry.
The Superchips patent
approved design provides by far the absolute best protection for your
engine by monitoring critical engine systems. In the unlikely event of a
component failure the smart processor senses the failure, shuts down the
unit and signals the driver with an amber MIL LED in the control switch. The
attractive machined enclosure is water tight and corrosion resistant.
Available in 3 options: Economy tuned, Performance tuned or Tow
tuned
With impressive reductions
in harmful exhaust emissions, increased horsepower, increased torque,
decreased fuel consumption and prolonged engine life, the Add-Gas Superchips
Diesel LPG Injection System is the first recommendation for the Ford range
of Diesels.
Propane when injected into
a Diesel Engine enhances combustion by evening out the normally violent
explosion that commonly occurs in the Diesel Combustion chamber. This
evening effect provides a more complete burn, a cleaner burn, a cooler burn
and a less violent burn resulting in lower exhaust gas temperatures, more
power, more torque, fewer emissions and the system pays for it self at the
diesel pump!
This system is a cost
effective new approach to help drastically reduce harmful black smoke and
NOX exhaust emissions commonly emitted from Diesel Engines and at the same
time save the customer money rather than add expense to their fleet.
By carefully monitoring
specific engine inputs, propane is injected into the air intake system prior
to the turbo charger through our unique venturi adapter at a predetermined
engine and vehicle specific rate programmed into our microprocessor. The
microprocessor is always in control of the stand-alone system and will shut
down and signal the driver if any problem with the engine is detected or in
the unlikely event that a component of the system should fail.
Now that’s peace of mind!

Economy of LPG/Diesel
Based on $1.20 litre (those where the days)
In this case the average price paid for diesel was $1.20 per litre and $0.40
for LPG.
On diesel only this Land Rover Defender returned 700km on average per tank
resulting in average fuel consumption figures of 10.7 litres/100km.
700km for 75 litres = 10.7l/100km. Cost to refill = 75 litres @ $1.20 = $90
This means $90 buys 700km on diesel only
Running the system on diesel/gas and still using 75l of diesel plus 28l of
LPG the Defender now consistently returns just over 1000kms an increase of
300km on diesel only scenario.
To cover the additional 300km on diesel only would cost:
300km @ 10.7l/100km = 32.10 litres required
32.10 litres @ $1.20 = $38.52
Therefore to cover 1000kms on diesel only the cost would be: 700km @ $90.00
+ 300km @ $38.52 = $128.52
To cover the same distance (1000kms) with diesel/gas the cost would be:
75l diesel @ $1.20 = $90.00 + 28l LPG @ $0.40 = $11.20 So diesel + LPG =
$101.20
So, the nett saving per tank would be $128.52 - $101.20 = $27.32 or 21% per
tank.
This saving doesn’t take into account the extra power (the dyno showed 34%
at this setting) giving you better drivability. Not to mention quieter,
cleaner and with less wear on the engine!
LPG/Diesel How does it work
High-pressure liquid petroleum gas (LPG) is converted to a low-pressure
(just above atmospheric) useable gas. The gas passes through a solenoid
valve (or stepper motor) which is controlled by outputs from the system’s
computerized processor measuring precisely the quantity of gas required.
This metered amount of vapor travels through a hose into the vehicle air
intake system and subsequently into the inlet manifold as a mixture of air
and gas.
The computer module (processor) controls the flow of gas optimizing
performance and ensuring safety. Manifold pressure (via a MAP sensor) or
throttle position (via a throttle position sensor) and engine speed are
monitored. The module then adjusts the gas flow depending on engine load and
driver demand. The amount of gas injected (or the ‘gas map’) is completely
(and only) programmable by a laptop computer. This allows a large degree of
flexibility to adjust the system to suit your requirements.
The system does not allow LPG into the engine at idle and is programmed to
limit the amount of gas introduced at maximum load to prevent over-fuelling.
The system shuts off gas flow when the brakes are applied or the driver’s
foot comes off the accelerator.
The system can be switched on and off (if ever necessary) via a dash mounted
switch. If gas is unavailable or you run out before a service station, it is
not necessary to switch the system off. Instead you will notice a decrease
in performance as the gas runs out. Since the diesel injection system is not
modified, the vehicle will simply run on diesel as it did prior to the
system being fitted.
As a result of the increased efficiency created by burning more of the
diesel injected into the combustion chamber, less diesel is now required to
travel each kilometre, therefore extending the range traveled on each tank
of diesel. Or, to look at it another way, the same amount of diesel will
deliver more power and torque.
Documented evidence indicates net fuel cost savings of 10-20% are achievable
running on either bio-diesel or normal diesel. A 4x4 vehicle will use
approximately one litre of LPG for every 25-30 kilometres traveled under
normal driving conditions. For further explanation, see Economy section.
Installations
The DieselGas system is manufactured, installed and certified under the
current Australian Standard AS1425. It is a similar installation to that of
a petrol/LPG conversion. As the LPG is not required to meet the whole fuel
demand of the engine smaller tanks can be used. This makes it easier to find
space under the vehicle to install the tank.

Computer module mounted out of the way under the dash of the Discovery.
A gas tank of approximately 1/3 diesel tank capacity is fitted to the
vehicle (a 30 litre gas tank is sufficient for 100 litres of diesel). A gas
fuel gauge and switch is mounted on (or in) the dash. A LPG filler is fitted
in a position convenient to the customer. All other components are mounted
in the engine bay. The system can also be removed and fitted to another
vehicle if required.
All components are manufactured and tested to AS1425, as for any other LPG
conversion.
Once the system is fitted and you have completed approx. 1000kms (and kept
accurate fuel usage records) we get the vehicle back to check the system and
make any adjustments as necessary based on your feedback.
