To convert a vehicle to run on AutoGas, a new fuel tank and propane injection system must be installed. Any gasoline engine can be converted to run on AutoGas, however there are several variables that will affect exactly what type of conversion works best for your own driving habits.
Why should I convert?
Bi-Fuel vs. Dedicated Mono-Fuel System
A bi-fuel conversion means the vehicle can burn both gasoline and propane. This is the system most motorists opt for, as it allows you to harness all the benefits of propane AutoGas for most of your driving while maintaining the ability to use gasoline where AutoGas is not available. There is no modification to the existing gasoline fuel system with a bi-fuel conversion.
Likewise, a dedicated AutoGas conversion will allow the vehicle to run only on propane, maximizing cost savings. This is a great option for vehicles that run specific routes or within a service area where AutoGas is readily available.
Liquid Injection vs. Vapor Injection
A liquid injection system keeps the propane fuel in liquid form right up to the point it is injected into the engine’s intake manifold. These systems follow the same basic design principle as the factory fuel system and tend to have trouble free performance. This the best option for most vehicles.
Vapor injection systems convert the propane to gaseous vapor before metering and injecting into the engine. They are usually less expensive than liquid injection systems, but often require more user input and adjustment, and they can be sensitive to extreme temperatures. If considering a vapor injection system, please consult us for advice and assistance.
Frequently Asked Questions About Propane AutoGas Conversions
Since holes must be drilled into the intake manifold for injector placement, (for a bi-fuel conversion) reversing a conversion may require installing a new intake manifold or plugging these holes in some other way.
A properly installed and tuned conversion should, it most cases, not cause any trouble for a vehicle’s on board diagnostic systems or ECM/ECU.
