How does a vehicle converted to Alternate Fuel operate?
Most vehicles converted to run on an alternate fuel such as CNG or Propane operate in a similar manner. There are a few differences, however. Here’s an example of how a vehicle converted to CNG (compressed natural gas) operates: • Natural gas is compressed and enters the vehicle through the natural gas fill valve. • Natural gas flows into high pressure cylinders located in the vehicle. • Natural gas goes through the high pressure fuel line and enters the engine compartment. • Natural gas enters the regulator which reduces pressure from up to 3,600 psi to atmospheric pressure. • The natural gas solenoid valve allows natural gas to pass from the regulator into the gas mixer. • Natural gas mixed with air flows down through the gasoline carburetor fuel injection system and enters the engine’s combustion chambers.
