  2. Catalytic Muffler • Engine and Equipment Manufacturers • Determine catalyst requirements • Determine secondary air requirements • Determine muffler performance requirements • Design and build prototype mufflers for evaluation with a muffler supplier • Heat verification and shielding development • Full load Heat testing • Heat soak during shut down • Off cycle temperature verification • Customer misuse of the choke • Misfire • Lack of maintenance ( air filter) The Outdoor Power Equipment Institute 341 South Patrick Street • Alexandria, VA 22314 • 703-549-7600 • 703-549-7604 FAX • www.opei.org
