How does it work?
The propane vapor injection system is boost activated, injecting propane in vapor form into the fresh air charge prior to the turbo charger. The amount of propane vapor injected is based upon the boost pressure of the engine. Propane acts as an accelerant, promoting a more even burn of the Diesel fuel resulting in more power, better fuel efficiency, lower operating costs and lower emissions.
Propane by itself will not ignite in a diesel engine. On the power stroke of a diesel engine with supplemental propane vapor added to the fresh air charge, the diesel fuel initiates combustion which in turn ignites the propane/air mixture in the chamber.
The result is rather than an explosion in a concentrated area where the diesel fuel is injected, we achieve a more even, complete burn, taking place in the entire chamber, utilizing more of the Diesel fuel charge. The engine basically becomes more efficient by burning more of the Diesel fuel charge in each compression stroke. Combustion efficiency is increased from approximately 75% to 95%.
The mechanical or electronic fuel injection system that the OEM installed on the engine will adjust the Diesel fuel trim (amount of fuel injected) to achieve the same RPM resulting in less Diesel fuel needed to perform the same function.
This also leads to lower operating costs, emission reductions including PM (particulate matter or black smoke) and NOX (oxides of nitrogen) since we are increasing the combustion efficiency of the burn of Diesel fuel.
This innovative design is only activated when the vehicle ignition is on and the engine is running.
The vapor injection system monitors the jake brake and immediately stops the flow of propane when the brake is activated and then restarts when the brake is off.
The system DOES NOT interfere with emissions equipment on the engine nor does it interfere with the OBD. We DO NOT tap into the fuel system.
A vehicle mounted vapor tank that is approximately 20% of the vehicles fuel tank capacity is necessary (Tanks sold separately).
What happens if I run out of propane?
If you run out of propane your engine reverts back to running on 100% diesel until you refill the propane tank.
Propane burns cleaner and cooler and in turn your engine runs cleaner, cooler and longer.
Propane can cost up to 60% less than diesel.
It increases the combustion efficiency of diesel from 75% to approximately 95%.
Propane increases the horsepower and torque of the engine.
There are approximately 3000 refueling stations nationwide so the support infrastructure is readily available.
Propane is NOT a green house gas, unlike CNG which is methane and is a greenhouse gas.
In addition, many Propane Suppliers will work with Fleets to install refueling systems at the Fleets location.
Propane is a domestically produced fuel.
Will my engine need to be modified?
No. The patented technology has been designed to allow for retrofit of diesel engines without the need to modify the design of the engine. The mechanical system is easy to install and has no impact on the vehicle's functionality. The system hardware is mounted under the hood (firewall) and there are no permanent modifications to the vehicle. The system does not need to interface with the vehicles ECM. No changes are made to the manufacturer's parameters. The vehicle continues to run on the fuel that the engine manufacturer designed it for.
Is it hard to install?
No. Detailed installation instructions are included with every system. Each component is
permanently and clearly labeled for easy installation. Technical assistance is available. On most applications installation should not exceed four hours. The system comes with everything you need to install it , except for the vapor propane tank which is ordered separately.
Will It help my mileage?
Yes. Fuel economy is increased significantly. You can expect a NET increase of up to 20% depending on the vehicle and your driving style.
Will the propane system affect my engine warranty?
Most OEM engine warranty programs do not prohibit the use of aftermarket parts or technologies. In brief, the policy of the OEM's is that they neither recommend nor endorse aftermarket technologies; however, the use of these products does not automatically void the validity of the engine warranty. If the cause of a failure is unrelated to the propane systems operation, the OEM's have historically honored the warranty.

What kind of vapor tank do I need?
The system requires the use of a securely mounted, properly oriented, DOT/ASME Vapor propane tank. Many different sizes and mounting options are available from 6"-24" in diameter and various lengths.
A DOT/ASME vapor tank is up to 20 times more puncture resistant than a typical fuel tank.
