Convert and Improve Diesels with Propane

Convert and Improve Diesels with Propane

Posted in Diesel, Greener Energy, Propane, Reduce Fuel Costs by cmsnetsol on March 12, 2009

People are becoming more interested in ways to reduce their fuel costs.

One such way is to convert your diesel engine with Propane (LPG) injection.

This technology was invented by Charles Butterworth in 1956 as a mechanical system but in recent years, has developed rapidly. Propane injection systems of today are user friendly, save more fuel, increase horsepower and produce cleaner exhaust.

The most recent development is the introduction of electronic controlled fuel injectors. These high tech injectors are designed to mix the precise amount of propane into the diesel engine air intake system in order to maximise the fuel saving and performance increases.

Only a few propane conversion kits come with electronic controlled fuel injectors. They are more advanced and do a much better job but are somewhat more expensive.

These conversion kits can be easily installed to fit your specific needs but the big advantage is the fact that if the propane tank should become empty, the engine can continue to function uninterrupted.

Below is a comparison of both typical average miles per (U.S.) gallon with and without the described kits for a number of different engines.


Below is a comparison of both typical average horsepower performance with and without the described kits for two different engines.


Following installation the immediate benefits include:

  • Reduced fuel costs
  • Increased performance
  • Increased service intervals from decreased oil dilution.
  • Much longer engine life.
  • An environmentally friendly engine with less smoke.

Frequently Asked Questions

Q. Could I install this system myself?
A. Yes, the kit comes complete with detailed instructions.

Q. Can it hurt my engine?
A. No, when installed and adjusted properly, engine life will be extended due to less oil contamination through dilution and lower combustion temperatures and pressures.

Q. How does it work?
A. Propane is fed into the engine air intake system via electronic fuel injectors for increased horsepower and decreased diesel fuel consumption.

Q. How does the computer control fuel delivery?
A. The computer senses turbo boost pressure as the primary input to control the fuel injectors.

Q. Why do we need a computer control?
A. To ensure the correct amount of propane is injected for all the varied engine load scenerios.

Q. Why are there 1 injector systems and 2 injector systems?
A. One injector systemwill provide adequate propane delivery for engines up to 7.5 liters in size and 2 injectors are used for engines more than 8 liters.

Q. What type of tank do I need?
A. Only a motor fuel tank with a vapor withdrawl port can be used. The tank must also meet NFPA 58 requirements.

Q. How much propane is injected compared to diesel? what is the diesel fuel to propane ratio on average? What are the horsepower gains?
A. The amount of propane injected varies with engine load. A 4 to 1 ratio is typical with a good increase in horsepower.

Q. How much will my diesel fuel comsumption decrease?
A. The diesel fuel consumption will decrease on average 10-15% is common

Q. What will this system do to my truck warrenty?
A. The Magmeson-Moss Warrenty Act (15 U.S.C. 2302 (C)) is a f ederal law that regulates warranties for the protection of consumers. The law means that the use of an aftermarket part alone is not cause for denying warranty. Your local truck dealer in most cases will warranty repairs for most aftermarket installations, however we recommend discussing the issue with your dealer prior to installation.

Q. Is there any regular maintenance that has to be performed?
A. No.

Q. How will it increase my service intervals?
A. When the diesel fuel entering the engine is reduced, less oil dilution and subsequent contamination occurs.

Q. How can it increase horsepower and fuel effieciency at the same time?
A. Injecting propane into the air intake system increases the celane rating of the diesel fuel which increases horsepower and efficiency.

Q. How is it different than an aftermarket chip of computer reflash?
A. Aftermarket chips and computer reflash increase the amount of diesel entering the engine which increases combustion temperatures and pressures, oil dilution and subsequent contamination also increases.

Q. How does it reduce the smoke and exhaust particulate?
A. The higher cetane rating created by propane injection increases the flame front speed in the cylinder for more complete combustion.

Q. How does the system adjust to cover individual driving styles and engine sizes?
A. Two adjustments are preformed; the first is at what turbo boost pressure propane will start to be delivered and the second is at what pressure the propane delivery is maximized.

Q. Can I park my truck in a garage?
A. Yes, tank have been proven to be safe when installed properly and filled to the correct level.

Q. Will engine or exhaust temperature increase?
A. No, the more efficient combustion created by the system will decrease exhaust temperatures when installed and adjusted properly.

Q. Where can I get my propane tank filled?
A. There are thousands of locations nationwide.

Q. Is propane less expensive than diesel fuel?
A. Yes, generally it is substantially less, but varies depending on location.

Q. If the propane motor fuel tnak is “used” are ther psecial requirements that must be met?
A. Yes, the data plate must be legible, there has to be a vapor port and no physical damage or excessive rusting should be present.

New Owners of these modern Conversion Kits are advised to consult with competent installers.

About the Author

The article above was written after devoting much energy, expense, and effort,to this system which is based on kits to convert and improve diesels with propane.

This system is unique in the sense that it is based on an interstate distribution of the kits, using central quality inspection and planning while using de-centralized local installation which fit local needs and local mechanics. As a result, the system is well spread while maintaining strict quality standards.

The installation work requires four hours on average and a special tank for the propane.

Since his boyhood Arieh enjoyed walking in the mountains in the fresh air and natural environment.

Arieh practiced domestic and international law, and engaged in international business and international banking in Israel, England, and the USA. For a while, Arieh also lectured on foreign credit and collection at Baruch college in Manhattan.

In the last few years Arieh became involved more and more in the field of cleaner environment and the interlock of increased fuel economy, increased horsepower, and decreased exhaust discharges.
