Standard Duty Catalytic Converter

History and How Your Catalytic Converter Works:
As early as 1974 in California and 1975 for the other 49 states of the USA motor vehicles have been equipped with Catalytic Converters. Invented in the mid 1950's by a French Mechanical engineer Eugene Houdry. Houdry was concerned about exhaust emissions and its impact on the environment. Invented years ahead of time Catalytic Converter were put into widespread use when emissions laws of the early 1970's were increased by both the California and Federal governments. Another result of Catalytic Converts is "unleaded fuel". Engineers for Detroit's Big Three discovered that the lead in fuel would cause contamination of the Catalytic Converters resulting in pre-mature and severe failures. This is the reason that any passenger car after 1975 can only use unleaded fuel. That is why your post 1975 car has the little gas flap door preventing you from using the larger leaded fuel nozzle. Early Catalytic Converters were bulky and prone to high heat due to the use of sulphur to convert the exhaust emissions. Due this sulphur base early converters had a "rotten egg" smell. Many reports in the early days of Catalytic Converters consisted of units setting leaves and lawns on fire when parked over them or rugs in cars going ablaze due to the high heat. Urban legends? Maybe. Due to vastly improved engine management systems, huge advances in Converter technology and use of ceramic and precious metals Catalytic Converters run much more cooler and efficient. A Catalytic Converter is a device used to convert toxic exhaust emissions from an internal combustion engine into non-toxic substances. Inside a Catalytic Converter a catalyst stimulates a chemical reaction in which noxious byproducts of combustion undergo a chemical reaction. The type of chemical reaction varies depending upon the type of catalyst installed, for example current North American gasoline powered Light Duty Vehicles are fitted with a Three-way Catalytic Converter which reduces carbon monoxide (CO), unburned hydrocarbons (HC), and oxides of nitrogen (NO, NO2, & N2O) to produce carbon dioxide (CO2), nitrogen (N2), and water (H2O). That water vapor is considered non-toxic for the environment. Since the early days of Catalytic Converters till today these devices are a vital part of your vehicles engine systems and performance. Keeping your engine and vehicle in correct running order will insure a long life for this complicated and delicate part of your vehicle.
