THE PERFORMANCE OF A MULTIGAP SPARK PLUG DESIGNED FOR AUTOMOTIVE APPLICATIONS

The electrical principle of operation, the geometrical and electrical circuit constraints on the design of, and the electrical and in- engine performance of a multi-gap spark plug developed for automotive applications are described. The measurements evaluating the in-engine performance of these plugs further indicate that improvements of up to 6% in fuel economy for a simulated CVS test run, the extension of the lean misfire limit by several A/F ratio numbers under various engine operating conditions, and improvements in driveability can be achieved compared to the performance of standard plugs under the same operating conditions. /GMRL/
