Efficient engines and catalytic converters

All Credit for this paper goes to: We owe him a big thanks This was my research project for my Physics of Modern Devices course which i took duringthe Spring semester of my Junior year in Rutgers. It was one of the electives i took for my minor in Physics. Oh well, at least i've passed the course right?

Efficient engines and catalytic converters

The catalytic converter warning light means the catalytic converter in your engine may not be working properly, possibly due to overheating. Without them, the quality of air around areas with lots of traffic would be significantly worse.

The catalytic converter works along with the oxygen sensors built into the exhaust system to monitor the fumes coming out of the engine and help the car stay as efficient as possible. A malfunctioning catalytic converter will throw off the oxygen sensor readings and your engine will not run as efficiently.

What the catalytic converter warning light means This light is made to warn the driver that the catalytic converter is either overheating or not operating as intended. The inside of the catalytic converter consists of a honeycomb design that increases the surface area in contact with the air. Over time, the metal can start to deteriorate and plug up the holes leading to overheating issues caused by restricted airflow.

Always have the oxygen sensors tested before replacing the catalytic converter. On newer cars, most manufacturers have gotten rid of the separate warning light for the converter and have tied in any issues with the converter into the check engine light.

Similar to the functioning of the check engine light, when this light comes on, you may or may not notice a difference while you are driving. Either way though, you should never ignore this warning light.

A certified technician will be able to hook up a scan tool to the car and read the code. Is it safe to drive with the catalytic converter warning light on? You still need to get the light checked out as small issues pretty much always turn into bigger issues, if neglected.

In the event that significant damage has or will occur, some vehicles may not even let you start the engine.

Like many other components on your car, you can usually save the catalytic converter by noticing the warning signs and rectifying them quickly.

If your catalytic converter warning light is on, get one of our certified technicians to help you diagnose any issues.There's a dozen engines listed for the '01 Jetta. The L V6 looks to have three converters. Two small ones in the down tubes and a larger third one further back.

The Misleading Nature of the PO42O Code - Eastern Manufacturing

An internal combustion engine (ICE) is a heat engine where the combustion of a fuel occurs with an oxidizer (usually air) in a combustion chamber that is an integral part of the working fluid flow circuit. In an internal combustion engine, the expansion of the high-temperature and high-pressure gases produced by combustion applies direct force to some component of the engine.

But, the efficiency of the converter is tied to the fuel trim of the engine. Most engines minutely alter the fuel trim to replenish the oxygen in the converter and to add fuel for reduction.

This helps to keep the converter at the correct temperature for the most efficient operation. In a regular catalytic converter, exhaust flows through a honeycomb network of rare-metal-coated microscopic channels, which run throughout a ceramic block. As the emissions contact the metal.
