A natural gas vehicle with compressed natural gas (CNG) propulsion works by using a high-pressure storage system to store the natural gas on board the vehicle. The CNG is then delivered to the engine through a fuel line and injected into the combustion chamber. The engine's fuel system and ignition system are modified to accommodate the use of CNG. The CNG is then ignited to produce power, similar to how gasoline or diesel fuel powers a traditional internal combustion engine. Overall, the process is similar to that of a gasoline or diesel vehicle, but with modifications to accommodate the use of CNG as a fuel source. **
