CATALYTIC CONVERTER Catalytic converters have been installed on vehicles since the mid1970s. They resemble a muffler but contain catalysts to reduce engine emissions before the exhaust stream exits the exhaust pipe (Figure 42.20). Some catalytic converters have a pipe attached to the air injection pump on the engine. Catalytic converters sometimes have a heat shield (Figure 42.21). A misfire allows raw gas to enter the converter because it Some manufacturers install a catalytic converter in the base of the exhaust manifold and another one downstream before the muffler. Catalytic converters can become Because of this, it has a heat shield to prevent heat from radiating to bodywork and other parts. The.catalytic converter is covered in coming from the exhaust system. Typically this means as much FIGURE 6540 A typical intermediate pipe between the catalytic converter and muffler. noise reduction as possible.Trunk liners come loose from the rear seat brace; gas cap sticking; troubleshooting tips for engine surging; rattling heat shield countermeasures (see following) : Catalytic Converter Heat Shield Rattle Models: '02 Camry January 18, 2002 Introduction: Under certain conditions, the heat shield for the catalytic converter on some 2002 model year Camry vehicles may be the source of a rattling sound. This rattle noise is most noticeable when driving at vehicle speeds above 50 mph [80 A ▷ catalytic converter is used to convert.unacceptable exhaust pollutants, such as carbon monoxide, hydrocarbons, and oxides of nitrogen into less dangerous substances. the airflow that goes through the throttle body to the individual intake valves that support combustion inside the cylinders. intake gasket Seals the manifold to the cylinder head; usually made out of plastic, rubber, or paper. muffler Component put on an exhaust system to muffle the noise created by the engine.Steering rack housing bushing noise. • Front shoulder belt anchor buzzes. • Front suspension groans. • Suspension rattle and popping. • Tailpipe contact with heat shield. • Headliner buzzes or rattles. • Moon roof rattles. • Manual front seat movement/noise. • Power front seat chattering..• Radio volume control too sensitive. • Rubbing noise from door trim.

Preconverter Samples. The 085.5mm x 120 mm long ceramic preconverter contains a 0.16 mm/620 kcpsm (6 mil/400 cpsi) substrate. This 0.69L preconverter uses a 6200 g/m2 intumescent mat canned to a GBD of 1.07. EXPERIMENTAL PROCEDURES AND RESULTS This section describes the experimental methodology followed to investigate and reduce catalytic converter radiated shell noise.The aluminium heatshields fulfilled the main specifications namely: •Heat resistance.up to 500 °C; • Low weight; • Easy recyclability; •Tear resistance. For the new solution, the authors wanted to add: •Acoustic absorption Acoustic design of the thermo acoustic shield. The maximum noise radiation around the catalytic converter to be treated was found to be above approximately 500Hz, so that the sound absorption of the heatshield to be designed had to be maximal in this frequency CONVERTER AIR INJECTION TUBE UPPER CONVERTER HEAT SHIELD DUAL BED CATALYTIC CONVERTER MUFFLER FRONT EXHAUST PIPE 3.
