Nissan 240SX Catalytic Converter

The Nissan 240SX Catalytic Converter, however, reduces toxic gases released into the environment by changing the carbon monoxide, hydrocarbons, and nitrogen oxides into water, carbon dioxide, and nitrogen. The Catalytic Converter in a Nissan 240SX exhaust path is installed downstream of the manifold at a spot where the heat of the exhaust activates the catalyst materials. Consisting of a monolithic honeycomb substrate coated with platinum, palladium, and rhodium, the internal working of a Catalytic Converter offers a large surface area for chemical reaction. Some units use ceramic beads to slow flow for similar chemical action. As exhaust flows over the catalysts, carbon monoxide and hydrocarbon oxidation and nitrogen oxide reduction are promoted, which cleans the emissions, and the catalysts themselves are not changed. A Catalytic Converter that is damaged or clogged creates backpressure, poor engine performance, rattling sounds, an illuminated check engine light, and high emissions that can fail a smog inspection. The Catalytic Converter of the Nissan 240SX is less likely to fail if misfires, rich mixtures, coolant leaks, and oil burning are avoided.

Nissan 240SX Catalytic Converter Parts Questions & Experts Answers

  • Q: What is the purpose of the catalytic converter in the exhaust system on Nissan 240sx?
    A:
    The catalytic converter is a muffler-like container built into the exhaust system to aid in the reduction of exhaust emissions. It consists of individual pellets or a honeycomb monolithic substrate coated with a noble metal such as platinum, palladium, rhodium or a combination. When the exhaust gases come into contact with the catalyst, a chemical reaction occurs which reduces the pollutants into harmless substances like water and carbon dioxide. There are two types of catalytic converters: an oxidizing type used on all models before 1980, and a three-way converter capable of reducing HG, CO and NOx emissions. The three-way converter requires precise oxygen control and is used only in cars equipped with an oxygen sensor system. All models with the three-way converter have an oxygen sensor warning light on the dashboard, which illuminates at the first 30,000 mile interval, signaling the need for oxygen sensor replacement. The oxygen sensor is part of the Mixture Ratio Feedback System, which uses the three-way converter as one of its major components. No regular maintenance is required for the catalytic converter system, except for periodic replacement of the Air Induction System filter. The Air Induction System is used to supply the catalytic converter with fresh air. Oxygen present in the air is used in the oxidation process. Precautions include using only unleaded fuel, avoiding prolonged idling, not disconnecting any of the spark plug leads while the engine is running, and making engine compression checks as quickly as possible. At present, there is no known way to reliably test catalytic converter operation in the field. Most converter problems can be traced to fuel or ignition system problems which cause unusually high emissions. As long as you avoid severe overheating and the use of leaded fuels it is reasonably safe to assume that the converter is working properly.
