Frequently Misrepresented Facts About CNGConversionsBy Jim YounkinAs I was introduced to CNG Conversions last year I was overwhelmed with lies and falsehoodsand under whelmed with solid information. Like everyone else as I searched the internet forinformation about CNG Conversions I kept coming up with a blank. What I did find out though isthat as I asked my peers almost everyone had an opinion about CNG Conversions. As I foundout later most of these opinions were false and unfounded. Those with the strongest opinions(which usually turned out to be rumors and innuendo) usually had something to gain byspreading them. I am compiling this list to dispel some of their misconceptions, now over a yearlater the real truth about CNG Conversions is finally coming out into the open.(1) Are CNG vehicles are more dangerous than gasoline vehicles?This is a false statement, natural gas is less volatile, and the CNG tanks are bullet proof andsafety tested. The CNG vehicle safety record is second to none. If gasoline vehicles were a newtechnology, they would never make it to the road, gasoline vehicles are burning up all the time,...(2) CNG Vehicles always run cleaner than gasoline.False, CNG can run cleaner than gasoline but it all depends on the tuning. Many "OEM" (originalequipment manufacturer) CNG conversions may out started out running clean, but over timemay go out of tune, all vehicles need retuning from time to time.(3) A CNG Conversion that is EPA Certified will always be clean and safe.False, An EPA Certification may start out clean but whether it is safe is the responsibility of theinstaller. The EPA Certification is to assure that the system will continue to burn cleanthroughout the "useful life" of the vehicle A little known fact is that since most all of the olderCNG Vehicles on the road today are EPA Certified. As these vehicles age they may developsleaks and runs dirtier, the older EPA Certified vehicles on the road today may be the dirtiest andthe most prone to leaks. Actually non EPA conversions since they are more readily tunable maybe cleaner as they age.(4) The EPA has been the biggest help to the CNG Conversion Industry through its regulationand monitoring.False, The EPA has actually been the biggest threat and burden on the CNG Conversion industryin the US. The linkage that ties a rebate to EPA Certification is illegal and favoritism on its face.
The installers overcharge about the same amount as the rebate. Fewer vehicles are convertedand many prospective CNG Conversion buyers are scared away.(5) The EPA can certify any CNG ConversionFalse, the EPA will only certify new vehicles; this is due to the factthat "Certification" testing is only valid within the "useful life" of avehicle, 100,000 miles.(6) EPA Certification never expiresFalse, this is one of the biggest misnomers in CNG Conversions.The Certification, like a vehicle "warranty" expires as the vehiclewears out. The certification expires after 100,000 miles.(7) All CNG Conversions must be EPA CertifiedFalse, this is the most vicious lie, the EPA will certify for a price a new vehicle but they have notime for or interest in the rest of the CNG Conversions as long as they are safe and clean.(8) Converting a Vehicle to CNG is considered "tampering" and is illegalFalse, "tampering" is causing a vehicle to run dirty or removing a pollution device from thevehicle. If a CNG Conversion runs clean it is as legal as any other car driving down the road.(9) A CNG Conversion system you buy on the internet is a recipe for disaster.False, its a sad fact that the United States is behind the rest of the world when it comes to CNGconversion components. The leaders in CNG System development are in Europe and SouthAmerica. There are many excellent CNG component manufacturers in the US but due to overregulation they have chosen to sell most of their CNG components outside the US.(10) Anyone installing a CNG Conversion must be trained by the EPA to be safe and legal.To a Certified mechanic this statement is really a laugh...First of all the EPA does not certifymechanics. ASE has a Alternative Fuel Certification called the F1, they also have certifications inall aspects of the automotive industry. CSA has a CNG tank inspection and there are otherorganizations who train in CNG installs. Any mechanic with moderate experience should be ableto install a conversion system. Of course they should be familiar with all NFPA52 safetyregulations and comply to them.
(11) When it comes to CNG Conversions the US is a world leaderFalse, the US is actually behind many third world countries when it comes to CNG Conversions.There are many states like Utah, Oklahoma and California who already have filling stations inplace but due to the vicious lies spread about CNG most vehicle owners have been scared away.(12) All Vehicles converted to CNG will loose fuel economy and power.Yes and No. Most CNG conversions may cause a slight loss in power but with some modern,sophisticated conversion systems you may actually gain power and economy. CNG/Dieselconversions actually increase power.
