Abstract
A new low-cost, simple, durable, yet highly efficient carburation system will greatly increase the viability of converting vehicles to run on natural gas. It has many major technical and commercial advantages over carburation systems now used. The system utilizes the OEM-computer gasoline injector signals, and precisely controls the instantaneous air : fuel ratio. This reduces the development and unit cost of the system and provides the natural gas to the engine in a precise relationship to what gasoline would have been supplied. It does not require any carburator, or mixer. It can be easily, quickly, and economically fitted to any fuel-injected vehicle.
