Catalytic Converter Diagnosis
The catalytic converter is probably the most important emission control device on a vehicle because it cleans up the pollutants in the exhaust. Thanks to fuel injection, oxygen sensors in the exhaust manifolds, and a feedback fuel control system, emissions are kept to a minimum. Even so, some pollution is still produced and must be
New Bosal Catalog Covers Import Exhaust and Catalytic Converters
Bosal’s new full-line import exhaust products catalog covers the company’s complete line of one-piece, direct-fit replacement import exhaust systems, mufflers, catalytic converters, pipes and accessories. More than 2,800 import makes and models, from Acura to Volvo, are featured along with complete application data, ordering information and illustrations.
Tech Tip: Catalytic Converters Play an Important Role in the Emissions-Compliant Engine
The design and function of catalytic converters has changed dramatically since their introduction in 1975. The first "two-way" catalytic converters were oxidizing-only designs that combined hydrocarbon (HC) and carbon monoxide (CO) with oxygen to form water vapor (H2O) and carbon dioxide (CO2). Oxidizing converters were originally manufactured in pellet bed or monolithic "honeycomb" styles. Currently, the monolithic style has proven to be the most durable.

Viewpoint: Cat Burglars and the Converter Cartel
How many catalytic converters can a battery-powered reciprocating saw cut from a dealer’s lot before the battery runs out? The answer is 18, according to news reports. In one night, 18 converters were removed at a Mentor, OH, Mitsubishi dealership. Other dealerships have been hit, with an average of 15 converters cut loose per night.
Codes & Converters
It is a moral dilemma that many shops encounter on a regular basis. It starts when a good customer comes in with the engine light a blaze. Running your usual diagnostics, you encounter a catalytic converter efficiency code, slow to responded oxygen sensor or some proprietary fuel trim code. Other than the light, the customer
Tech Tip: Oxygen Sensors – Monitoring Converter Efficiency
In 1996, automakers did the aftermarket a huge favor. They added "downstream" oxygen (O2) sensors to their vehicles. The downstream O2 sensors are located just behind the catalytic converter, or on some Fords, in the converter itself.
Eastern Introduces New 2006 Catalog Featuring Catalytic Converters and Related Components
Eastern Manufacturing, a manufacturer of catalytic converters and related components, has introduced a new catalog, which features the complete line of direct-fit, performance and universal catalytic converters for cars, vans, and light- and heavy-duty trucks.
Exhaust & Emissions: Converters & O2 Sensors
What’s the most important emissions control device on a vehicle today? The catalytic converter, because it cleans up any exhaust pollutants that exit the engine. It’s a hot job (literally) with operating temperatures running between 600 to 1,000
Replacing Oxygen Sensor: Saving the Environment and Your Customer’s Catalytic Converter
The oxygen (O2) sensor is the master switch in the fuel control feedback loop. The sensor monitors the amount of unburned oxygen in the exhaust and produces a voltage signal that varies from about 0.1 volts (lean) to 0.9 volts (rich). The computer uses the O2 sensor’s signal to constantly fine tune and flip-flop the
