What’s the difference between a regular conversion and a sequentially injected propane conversion?
A. A regular conversion delivers the propane vapor to the engine via a mixer that mounts before the intake. This system is called gaseous propane carburetion. When the propane is activated, the gasoline injectors are shut off and the propane enters the engine very much like a carburetor would deliver gasoline. This is the primary system that has been used in North America for decades. Its main benefits are its relatively low cost, simplicity of design and adaptability to all vehicle types. The main drawbacks of this system are its susceptibility to backfires if not properly maintained and its lack of horsepower (about a 10% drop). The sequential propane injected system is a major leap forward in technology. As the name implies, it uses electronic fuel injection to delivery the fuel to the engine. The main benefits of utilizing a far more advanced injection system are: the elimination of all backfires, an increase in fuel economy and engine performance equal to gasoline. The computer-co
