    Propane Ignition Characteristics

    Hi Paul, I am no expert by any means on this matter but I just finished a conversion to LPG from CNG due to refueling stations closing. My Van is a 5.2L Dodge with a multiport fuel injection system used with CNG previously. I have been running LPG at 50 psi at the fuel rail and had some of the...

    CNG Vehicle conversion to Gasoline

    Thanks Franz for the data. I found some of the same data at www.mipga.org/PhysProp.htm. The Vapor Pressure LB/SQ IN at 60 Deg F is 92 psi. Question; Is this a linear equation? If so I can calculate vapor pressure under various weather conditions. Also WOT is not a priority for this project...

    CNG Vehicle conversion to Gasoline

    Franz, Thanks for the info but I am currently an unemployed Manufacturing Engineer with some time on my hands and thought it would be an interesting project to convert. It is my understanding that the computer will relearn fuel maps and system changes up to 40%. According to my calculations it...

    CNG Vehicle conversion to Gasoline

    Thanks gbent and Pat, Yes, I thought about selling it but it only has 20,000 miles on a 5.2L engine. After buring CNG for 20,000 miles the engine is all but new. The LPG conversion sounds reasonable but I have little experience with LPG vs Ethonal. Is there an LPG expert out there that can...

    CNG Vehicle conversion to Gasoline

    Thanks Franz for the info. Would it make more sense to convert the CNG vehicle to E85 (Ethanol) and use the injectors that are installed. The existing fuel lines are Stainless Steel therefore with the addition of a Stock polypropolene 35 gal tank and a Ethonal safe fuel pump and regulator it...

    Racing using moth balls?

    Guys, here is a site that will allow you to purchase gasoline additives or alternative fuels that actually help clean the air. E85 (85% ethonal) is sold in many parts of the country. Yes, your system needs to be compatible with ethonal since it is somewhat corrosive but a 10% mix will boost your...

    CNG Vehicle conversion to Gasoline

    I am about to embark on a conversion of my dedicated CNG Dodge 5.2L full size van to gasoline due to the closing of CNG refueling locations in the Midwest. The Engine has a 10.5:1 compression ratio. I am going to attempt to run this engine on Premium gasoline with 10% ethonal. Question, will the...
