CNG BusENSIDA Energy is the NAFTA distributor of Ensida compressed natural gas (CNG) conversion systems. It is a modern sequential injection type system characterized by high quality components, innovative electronics and minimal electrical connections.

Our CNG conversion uses the injector pulses from the OEM electronic control unit to time the CNG injectors. The results are excellent drivability, low emissions and no alteration of the onboard diagnostics (OBD). The ENSIDA sequential injection system SGI-3 is the latest technological evolution offered by ENSIDA Energy. The ease of installation and calibration make the SGI-3 system extremely versatile and innovative. Ensida CNG system use the same GAME electronics and software used for the LPG system, but with the ECU loaded with the CNG firmware.

The GAME software, switched in CNG function, has been designed basing on the same concept of “full control” plus a consistent strategy package making GAME the most powerful tool to obtain the maximum performance and efficiency of the vehicle converted with CNG fuel. An additional electronic control on the ignition advance strategy (not available for all vehicle models) optimize and reduce the typical loss of engine power when the engine is working in CNG mode, compared to gasoline perfomance. ________________________________________________________________________________

Compressed natural gas is the cleanest burning fuel operating today. This means less vehicle maintenance and longer engine life. CNG vehicles produce the fewest emissions of any motor fuel. Natural Gas Vehicles (NGV) have little or no emissions during fueling. In gasoline vehicles, fueling emissions account for at least 50% of a vehicle’s total hydrocarbon emissions.

CNG pumpOperators have reduced maintenance costs by as much as 40% by converting their vehicles to CNG. Intervals between tune-ups for natural gas vehicles are extended 30,000 to 50,000 miles. Intervals between oil changes for natural gas vehicles are dramatically extended. Anywhere from 10,000 to 25,000 additional miles depending on how the vehicle is used. Natural gas does not react to metals the way gasoline does, so pipes and mufflers last much longer.


CNG engines are superior in performance to gasoline engines. CNG has an octane rating of 130 and has a slight efficiency advantage over gasoline.


Because CNG is already in a gaseous state, it has superior starting and driveability characteristics, even under severe hot and cold weather conditions. NGVs experience less knocking and no vapor locking. Natural gas is cheaper per equivalent gallon than gasoline. Approximately half.
