| Abstract |
The report summarizes an effort to study the emissions of vehicles that had exhibited variability on I/M tests and then to determine the effects of various preconditioning cycles on the I/M tests of those vehicles. The Federal Test Procedure hydrocarbons and carbon monoxide emissions of the vehicles continued to fail the I/M test even after loaded preconditioning tended to be higher than the emissions of the I/M-failing vehicles which passed after that loaded preconditioning. Among the closed-loop vehicles, the fuel injected cars appeared to be more likely to produce consistent I/M results than were the carbureted cars. |
