REGULATED AND UNREGULATED EXHAUST EMISSIONS FROM A MALFUNCTIONING THREE-WAY CATALYST GASOLINE AUTOMOBILE

This report describes the laboratory effort to characterize regulated and unregulated exhaust emissions from a current model three-way catalyst-equipped gasoline automobile operating under malfunction conditions. One automobile was evaluated over three driving schedules in the unmodified configuration and in four engine and/or emission control system malfunction configurations. Exhaust emission constituents measured, in addition to the currently regulated emissions, include: particulates, sulfates, aldehydes, sulfides, amines, metals and several additional elements and compounds. Additional evaluations, in each of the configurations, involved the measurement of the regulated emissions over four short-test procedures.
