POWERSHOT TURBOCHARGED
PROPANE INJECTION SYSTEM
INTRODUCTION
• Powershot is a propane injection system for turbo
diesel owners.
• This system guarantees the ones who are looking
for more power and mileage.
• This system is unique from other propane
injection systems in the market owing to it
innovative and patented design.
• This is an easy to install system which will safely
and substantially increase horse power up to
100hp and torque up to 250 ft lbs.
TURBOCHARGERS
• Turbochargers allow an
engine to burn more fuel
and air by packing more
into the existing cylinders.
• The typical boost provided
by a turbocharger is 6 to 8
pounds per square inch
(psi).
• You would expect to get
50 percent more power.
It's not perfectly efficient,
so you might get a 30- to
40-percent improvement
instead.
TURBOCHARGERS
• The turbocharger is bolted to
the exhaust manifold of the
engine. The exhaust from the
cylinders spins the turbine,
which works like a gas turbine
engine.
• The turbine is connected by a
shaft to the compressor, which
is located between the air filter
and the intake manifold. The
compressor pressurizes the air
going into the pistons.
• The exhaust from the cylinders
passes through the turbine
blades, causing the turbine to
spin. The more exhaust that
goes through the blades, the
faster they spin.
PROPANE FUMIGATION
• Propane (LPG) Fumigation is the introduction of gaseous
propane into the air intake of a diesel engine for the
purposes of attaining more power, economy, or both.
• The parallel is often made between fumigation and using
Nitrous Oxide on gasoline vehicles to achieve a power
increase.
• This analogy is correct, although the properly implemented
use of LPG on a diesel engine will actually result in a
better-running engine without the possible damaging
effects that N2O has on gas motors.
PROPANE FUMIGATION
• Exhaust emissions are reduced as a result, with
lower quantities of unburned hydrocarbons and
fewer particulates (smoke)
• LPG fumigation will even clean up the odor of
diesel fuel in the exhaust, making the smell from
the tailpipe of an engine utilizing it much less
objectionable.
HOW PROPANE WORKS ?
• Introducing LPG gas into the combustion air intake of a
diesel engine acts as an accelerant, promoting the even
burning of the diesel fuel, and more complete combustion,
resulting in more power being produced.
• During the compression stroke, the air/LPG mixture is
compressed and the temperature is raised to about 400˚C,
not enough to ignite the LPG, which has an ignition
temperature of about 500˚C.
• When the diesel fuel is atomized into the cylinder under
high pressure, it immediately self-ignites (diesel ignites at
about 385˚C.), and causes the LPG to burn as well.
HOW PROPANE WORKS ?
• Much of the cleaner burning of the fuel is attributed to this
ignition against the "cooler" components of the engine, and
accounts for raising the percentage of combustion from a
typical 75% for a well-tuned diesel engine running on pure
diesel fuel alone, to 85-90% with the addition of LPG.
• With a turbocharged engine the combustion is again
increased to 95-99%.
• This more complete combustion also gives a nice boost in
power, with an accompanying increase in fuel economy
and reduction of pollutants.
WHAT TO EXPECT ?
• Normally-aspirated engines require different systems to
introduce the gas than do turbocharged engines. The
results are different as well.
• Fuel economy is increased significantly. You can expect an
increase of 2-3 mpg (3-4 km/l ) depending on your driving
style.
• Displacing 1% of the intake air with LPG will result in a
small power increase, perhaps 5-8%.
• Turbo engines are by design blessed with a lean air-to-fuel
ratio, and can be fed concentrations of LPG up to about 68% of the intake air volume.
INSTALLATION TANKS
ORIFICE ACTION
• Metering systems for gas
pressure devices generally
include an orifice, or jet to
control flow.
• Fixed orifices must be
drilled out to increase the
flow for a given pressure,
while adjustable units can
be manipulated with a
wrench or similar tool to
change the quantity of gas
that passes.
Supplying Gas to the Intake
• This where the powershot
injection system is used.
• Fumigation introduction on a
turbocharged engine usually
takes place before the air intake
to the turbine, allowing the
turbo to help mix the propane
with the intake air.
• Adding the gas after the turbine
output is possible, but you will
need to account for the boost
pressure, raising the LPG
regulator to a value greater than
the turbo's output, typically by
3-6 PSI.
CONTROL SYSTEMS
• The piece of gear seems to be the sticking point in many of
the LPG systems that I hear about.
• Essentially a solenoid valve is an electrically actuated
valve that is used to control the flow of gas into the engine.
• The 12 volt power to run the solenoid valve is supplied
from the switched side of the ignition system. This insures
that the gas is always off when the ignition switch is off.
The supply wiring to the rest of the circuit is protected by a
fuse.
CONTROL SYSTEMS
• On/Off switch on the
dashboard. On THIS
system, IT uses the gas for
a boost during passing and
hill climbing mostly, so It
need to be able to control
the LPG "on the fly". It's a
good idea to have one on
any system, so that you
can defeat the gas when
the engine is cold, or in
case a problem requires
shutting down the gas.
CONTROL SYSTEMS
• A throttle-mounted switch
to prevent gas from
entering the engine during
idle conditions. You don't
need additional power
while sitting stopped at a
signal, and from
experience, I can tell you
that you probably won't
remember to shut it off
manually. Adding gas
during idle will also result
in a fast idle, which isn't
necessary either.
CONTROL SYSTEMS
• An interlock that prevents gas from entering the engine
when it isn't running. "Oh, isn't that the ignition switch"?
you ask. No, it's not.
HAZARDS
• LP gas, like any combustible fuel can be dangerous
• If you are going to attempt to construct your own
fumigation system, be aware of the hazards present when
you use this fuel.
• Use proper fittings and fixtures, and be aware of the high
pressure present at the output of an LPG storage tank.
• Any containment of a tank must be properly vented. Never
check for gas leaks using a flame.
• adding fumigation equipment to a diesel engine is
becoming a commonly accepted practice, keep in mind that
doing so may void your warranty, negate any emissions
certifications your engine has and/or violate local or state
vehicle codes.
