Abstract
The exhaust emission characteristics of the Biap device on a used vehicle were studied as part of an evaluation of retro-fit devices. The Biap device is attached to both sides of the coil on a 1963 Ford Galaxie with a 289 cu. in. engine and automatic transmission. This car was also equipped with the Ford retro-fit kit. The following tests were conducted: (1) a closed constant volume sampling technique using 9 repeats of the 1970 Federal emissions tests cycle (CVS); (2) a closed constant volume sampling technique using the LA4-S3 driving schedule as specified for 1972 and later testing. Bag samples were analyzed for carbon monoxide, carbon dioxide, hydrocarbons, and nitrogen oxides. It was concluded from the results obtained, that the 'Biap Electronic Ignition Unit' has no positive effect on exhaust emission rates when evaluated using the constant volume sampling technique.
