LPG - Liquefied Petroleum Gas
Propane Carburetion. Fumigating propane into an engine.
Propane engines make higher demands on the ignition system compared with that required of a gasoline engine. This higher demand is due to the characteristics of the fuel which requires a higher ionization energy. While it might seem that simply creating a voltage across a gap results in a spark, there are few things that happen before a spark jumps across the spark plug electrodes.
Propane Fuel Tanks
Propane or LPG fuel systems are manufactured world-wide. Each manufacturer has a target market and, for most, it is the fleet market as this is where the largest volume of sales would typically be. Impco was one of the early system manufacturers and they still make products for older carbureted vehicles. There were a number of other manufacturers that appeared at the time like Century and Beam but these have either gone out of business or have been absorbed by larger companies such as Impco. Some, like Holley, were only in the business for a short time.
