Propane Dual Fuel System

Dual Fuel is a propane injection system that can be easily retrofitted on diesel and gasoline engines, and results in improved Miles-Per-Gallon (MPG), reduced fuel costs, cleaner oil and reduced emissions.
This innovative design is only activated when the engine is running. Installation requires no permanent modifications to the vehicle or engine. The idle circuit quiets the engine and reduces emissions.


  • Can increase your Miles-Per-Gallon up to 25%

  • Boost pressure activated

  • Reduces exhaust emissions

  • Increases Power and Torque

  • Provides Cleaner Oil

  • Increased interval between DPF (Diesel Particulate Filter) regeneration

  • Improves combustion efficiency from 75% up to 95%

  • Monitors boost pressure and Jake Brake

  • Does not interfere with the Engine Management System (EMS)

Selph's Propane Dual Fuel


  • Our technician can install the system in approximately 4 hours, depending on the location of the propane tank. In the event you would like to install the system yourself, detailed instructions are provided with the system.

  • No connection to the vehicle's computer or cooling system, or remapping or the vehicle fuel system. It is controlled, activated and proportionate to the boost pressure of the engine.



  • The Dual Fuel system works by introducing Propane (LPG) into a turbo charged diesel engine. The propane is injected in the fresh air charge prior to the turbo charger. Propane is delivered in a vapor form via the Dual Fuel's metering system. The amount of Propane injected is based upon the boost pressure of the engine. Propane acts as an accelerant, promoting a more even burn of the diesel fuel. This evening effect provides a more complete combustion of the diesel fuel. The result is more power, better fuel efficiency and lower emissions.

  • Propane itself will NOT self ignite in a compression ignition diesel engine. On the power stroke of a diesel engine, diesel fuel is injected initiating combustion, which in turn ignites the Propane/air mixture in the chamber. The result of this action: rather than a violent, rapid explosion in a concentrated area where the fuel is injected, a more even, smooth burn takes place in the entire chamber further down the power stroke, thus utilizing more of the diesel fuel charge.

  • Fuel efficiency can be significantly increased by the vapor injection system with the accelerated evening effect of combustion. The diesel engine becomes more efficient by burning more of the diesel fuel charge in each compression stroke. Combustion efficiency is increased from approximately 75% to 95%. This leads to emission reductions including PM (particulate matter or black smoke) and NOx (oxides of nitrogen). The majority of the unburned diesel fuel that would normally be expelled out the exhaust or drop back into the crankcase is now burned thus generating more energy per gallon of diesel fuel used. The mechanical or electronic fuel injection system will adjust the diesel fuel trim (amount of fuel injected) to achieve the same RPM which results in less diesel fuel needed to perform the same function. When the typical diesel engine is under full load, the fuel system can only inject a given amount of fuel as determined by the Original Equipment Manufacturer (OEM). By introducing the proper amount of propane to the combustion chamber under full load, more of the existing diesel fuel injected is burned safely. This results in a dramatic increase in horsepower and torque without risk to the engine.

  • The Dual Fuel system does NOT interfere with emissions equipment on the engine, nor does it interfere with on-board diagnostics. There is no connection to the ECU (Electronic Control Module) or remapping of the fuel system required.



  • Most Original Equipment Manufacturer (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 the products does not automatically void the validity of the engine warranty. If the cause of failure is unrelated to the propane system, OEM's have historically honored the warranty.
