Device Tested
The exhaust emission characteristics of the. Biap device on
a used vehicle were desired for use as part of an evaluation
of retro-fit devices. The Biap device is attached to both
sides of the coil according to the manufacturer's recommen-
dations on a 1963 Ford Galaxie with a 289 cubic inch engine
and automatic transmission. This car was also equipped with
th~ Ford retro-fit kit and extensive background data on emis-
sion levels was available.
Test Procedure
The following tests were conducted:
1. A closed constant volume sampling technique using 9
repeats of the 1970 Federal emissions test cycle. (CVS)
2. A closed constant volume sampling technique using
the LA4-S3 driving schedule as specified for 1972 and
later testing.
Closed cycle data were taken using a constant volume sampling
technique. Bag samples were analyzed using non-dispersive
infrared analysis for carbon monoxid~ and carbon dioxide
with.hydrocarbons measured using ~ f~ame ionization detector.
The Whittaker "NOx Box" was used for 'determination of ox:~des
of nitrogen in the CVS sample.
Emission Results
The data shown in Table I compare tests run both with and
without the Biap device.
Using the 9 CVS procedure increases in hydrocarbons, carbon
monoxide, and oxides of nitrogen were measured with the de-
vice; with the 1972 FTP increases in carbon monoxide and
oxides of nitrogen and a decrease in hydrocarbons were found.
Because of the lack of significant change it appears that
the Biap device has no positive effect on exhaust emissions.

Conclusions'
The "Biap Electronic Ignition Unit" has no positive effect on
exhaust emission rates when evaluated using the constant
volume sampling technique.
