The Assurance of Quality for After-Market NGV Conversions “Fleet Involvement”

A Quality Assurance Program for Compressed Natural Gas (CNG) Conversions that was developed in 1995 and subsequently put in place by the Fleet Services Department of BC Gas Utility Ltd in British Columbia, Canada has provided substantial improvement in the areas of emission performance overall vehicle driveability and user acceptance, as compared to previous conversion programs within the BC Gas fleet. This program, which is possibly the first of its kind for a North American Natural Gas Utility, ensures that all of the after-market CNG conversions meet and/or exceed the guidelines established by the Utility that pertain to equipment standardization, certification, emission standards and non-tampering of OEM configurations.
