The Catalytic Converter used in the Chevrolet Malibu cars is a major component of the exhaust and emission system which has a function of changing the toxic gases prevailing in the exhaust emissions to harmless gases. Its major work is the conversion of Carbon Monoxide (CO), Hydrocarbons (HC), and Oxides of Nitrogen (NOx) to water, Carbon Dioxide (CO2), and Nitrogen (N2) by the use of certain chemicals such as platinum, palladium, and rhodium. Conventional catalytic converters that have been used in Chevrolet Malibu model of the car include the two-way and the three-way converters. The use of three way converters from early 1980s enabled reduction of NOx emissions concurrently with oxidation of CO and HC. However, like most other converters of today, regardless of how they are built with an aim of creating low backpressures, they are associated with certain problems such as blockage and heat build-up which are significantly known to be related to engine performance. Proper servicing and replacement as required should be observed so that the catalytic converter of Chevrolet Malibu would work cohesively and would meet emissions requirements.
