CNG: Quality and safety is our number one priority. Vehicle Conversions : For valuable resources pertaining to conversion to natural gas vehicles, please refer to:

Convert a vehicle to natural gas to save on gas costs and do you part to help the environment. Natural gas burns cleaner, which means less harmful emissions. Most natural gas vehicles use compressed natural gas (CNG), which can be refueled at home or at special filling stations, but cars can also be converted to use liquefied petroleum gas (LPG) or propane.

Natural gas has long been considered an alternative fuel for the transportation sector. In fact, the first internal combustion engine vehicle to run on natural gas was created by Etienne Lenoir in 1860!

Most natural gas vehicles operate using compressed natural gas (CNG). This compressed gas is stored in similar fashion to a car's gasoline tank, attached to the rear, top, or undercarriage of the vehicle in a tube shaped storage tank. A CNG tank can be filled in a similar manner, and in a similar amount of time, to a gasoline tank.

CNG Vehicle Conversions (Compressed Natural Gas)

CNG is stored on board vehicles in (3,000-3,600 psi) tube-shaped cylinders that are installed in the trunk, roof, bed or undercarriage of the vehicle. The cylinders meet very rigorous safety standards. They are made of high-strength materials designed to withstand impact, puncture and, in the case of fire, their pressure relief devices (PRD's) provide a controlled venting of the gas rather than letting the pressure build up in the tank.

(b) Regulations.- The Administrator shall, within 24 months after the enactment of the Clean Air Act Amendments of 1990, consistent with the requirements of this title applicable to new vehicles, promulgate regulations governing conversions of conventional vehicles to clean-fuel vehicles. Such regulations shall establish criteria for such conversions which will ensure that a converted vehicle will comply with the standards applicable under this part to clean-fuel vehicles. Such regulations shall provide for the application to such conversions of the same provisions of this title (including provisions relating to administration enforcement) as are applicable tostandards under section 242, 243, 244, and 245, except that in the case of conversions the Administrator may modify the applicable regulations implementing such provisions as the Administrator deems necessary to implement this part.

(c) Enforcement.- Any person who converts conventional vehicles to clean fuel vehicles pursuant to subsection (b), shall be considered a manufacturer for purposes of sections 206 and 207 and related enforcement provisions. Nothing in the preceding
sentence shall require a person who performs such conversions to warrant any part or operation of a vehicle other than as required under this part. Nothing in this paragraph shall limit the applicability of any other warranty to unrelated parts or operations.

(d) Tampering.- The conversion from a vehicle capable of operating on gasoline or diesel fuel only to a clean-fuel vehicle shall not be considered a violation of section 203(a)(3) if such conversion complies with the regulations promulgated under subsection (b).

(e) Safety.- The Secretary of Transportation shall, if necessary, promulgate rules under applicable motor vehicle laws regarding the safety of vehicles converted from existing and new vehicles to clean-fuel vehicles.
