British Columbia Vehicle Emissions Inspection and Maintenance Program Experience of Alternative Fuel Vehicle Conversions 941913

Basing its conclusions on over one million gasoline vehicle inspections and over 30,000 alternative fuelled vehicle inspections, this paper examines the pass/fail records for each fuel; the problems most common to failing vehicles; and repair strategies used to correct those problems.
The paper specifically describes the relationship between the level of technology used in alternative fuel systems and their emissions performance. It is shown that alternative fuelled vehicles are not inherently clean, and that to meet the same emissions standards as gasoline vehicles the alternative fuel system should employ the same level of technology as used in the original gasoline vehicle.
