CleanFUEL USA Receives EPA and CA Certification for Propane Engine Conversion System
9 June 2008
CleanFUEL USA has received US EPA and California Air Resources Board (CARB) certification of a propane engine system that is an OEM replacement technology for both new and aftermarket gasoline-powered engines.
CleanFUEL’s liquid propane fuel injection (LPI) system is a drop-in and replace propane conversion system for 8.1L gasoline engines, designed to convert medium-duty fleets, such as school buses, shuttle buses and 4500-8500 series GM trucks, to operate on propane. LPI meets EPA requirements through the 2010 production year for both 49 state and CARB certification.
LPI is a fully integrated system, designed in harmony with the OEM engine. Utilizing the GM P-59 engine computer with a dedicated calibration specifically for propane, the LPI system replaces the gasoline fuel tank, fuel pump and injector rails with a propane fuel tank, fuel pump and injector rails.
The LPI system replaces the gasoline injectors with propane injectors, delivering the propane to the cylinders in a liquid form. This results in lower intake valve temperatures, denser air-fuel charges, more complete combustion, lower emissions, and improved fuel economy and performance.
Propane (also known as liquefied petroleum gas, LPG) is currently in surplus worldwide with 90% of US propane produced domestically when combined with supply from Canada.

I've been following this technology through media releases from South Australia for about six years.
Including the later attempts at dual system gas and petrol, as we call them which was having integration problems. These days LPG is so widely available, dedicated lpg should not be a problem here.
I am not aware of the current status of this, I thought some one was supplying as OEM, but probably wrong.
liquid injection will bring the latent coolth of evaporation closer to the combustion chamber and DI if made available will provide the most benefit.
The local college instructs techs on the Accordion or harmonica box sequential technology by Dream. Which can pulse vapour injection. Apparently very good but to maximise the cylinder heat absorbed by liquid is the way to go.
Its a worry though that at the present rate of consumption, LPG will relatively (very) quickly see market shortages.
If you techs get a chance to play with this,do and consider it as intro to Natural gas tehnology.

the basic technology is very old, but it works perfect. It has been applied in the Netherlands for more than 50 years and every gasoline car can be transferred into LPG and gasoline fueled. The fuel costs are here 2,5 times lower with LPG than with gasoline. The costs for building a LPG system in is between 1200 - 2300 euro.

Bio-engineering should get bacteria to make propane rather than methane. Liquid propane is the most convenient ideal fuel; that is why you can find it in most stores. A gas at low pressure and a liquid at high pressure for compact storage. Butane is ok for room temperatures. DME can be stored like propane but used in diesel engines directly, and china is building a big production facility from coal. I saw propane fueled gasoline delivery trucks fifty years ago. Butanol is a liquid good for unmodified present cars. ..HG..

Is it possible to convert a Dodge stratus to propane

Bravo Clean Fuel USA!
If propane is available and results in lower emissions than gasoline as well as lower cost, we might as well use it.
