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 6-8% of the intake air volume.
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.
POWERSHOT INJECTION SYSTEM • Simplicity is the key to getting the performance you want out of your truck. • Our patented design means: No mixers, sensors, evaporators, or switches to hassle with or adjust. • Easy installation and maintenance. • Cleaner burning fuel. • Better fuel economy. • Increased torque and horsepower for towing.
APPLICATIONS • The Powershot 2000™ Propane Injection Kit is the perfect addition for your turbo diesel engine to gain horsepower at an affordable price. • The Powershot 2000™ is boost pressure activated, injecting propane into the engine as the boost pressure of the engine increases producing a throttle control, that you will definitely feel behind the wheel. • Safety features such as: Power switch inside the cab so driver has full control of turning the system on and off. Fuel lock off valve, stops the flow of propane unless the vehicle ignition and system is on. • Fits all FORD, DODGE AND GM TURBO DIESELS. • An adjustable orifice allows you to change flow rates from towing to performance effortlessly in minutes. • Variable flow rate delivers smooth, steadily increasing power, proportionate to the boost pressure.
FEATURES • A securely mounted DOT approved certified propane tank, available at most RV and propane dealers, at least 25% of your vehicle fuel capacity. If a vertical tank is used, the tank must be securely mounted in the upright position only. A 20lb tank should be good for a range of at least 500 miles depending on your driving style. • Diesel Performance Products provides detailed installation instructions with every Powershot 2000™ propane injection kit sold. Each component is permanently and clearly labeled for easy installation. Installations on most applications should not exceed two hours. • Should your vehicle require a trip to the dealer for routine maintenance or repairs, the Powershot 2000™ is easily removable and labeled for ease in reinstalling.
