It will not work better if it is hot or cold if it is clogged. Replace it.
Catalytic converters are a device in the exhaust system that helps reduce the toxicity of emmisions put out by cars. They work by heating up the metal structure and burning up any left over gasses from the combustion of the cylinder.
It's not up to you, when to "make the catalytic converter to work"!... The catalytic converter will provide the chemical reaction alone only @ 400 > degree, no options! See/Google "how it works" and that will help you understand how and why!
Catalytic converters are used to reduce emissions, however they only work at high temperatures, while they are warming up they do not reduce emissions, so the quicker they are functioning, the lower the emissions will be.
A quality aftermarket catalytic converter will work fine as long as everything else is in good working order.
On a Nissan 350Z, oxygen sensors are located in two main areas: the upstream (pre-catalytic converter) sensors are positioned on the exhaust manifold, while the downstream (post-catalytic converter) sensors are found on the exhaust pipes after the catalytic converters. The upstream sensors monitor the air-fuel mixture, while the downstream sensors check the efficiency of the catalytic converters. Accessing them typically requires some work under the vehicle or from the engine bay.
Many of the compounds that make your engine oil work better on the INSIDE of the engine are also "poisonous" to your catalytic converter as your engine starts to use oil. The nice thing about catalytic converters, they burn unused hydrocarbons that come out the exhaust. You may not KNOW that your engine is burning oil until the catalytic converter gives out or even gets plugged up. Watch the oil level in the crankcase. If it drops with no evidence of leaking, it's burning and your catalytic converter will die.
A catalytic converter works by the various precious minerals and metals inside it. Quite simply they convert the dangerous chemicals inside the exhaust gases(carbon monixide,NOx etc) into less harmful ones (carbon dioxide etc). Due to the minerals and metals inside though they are often target to thieves as they can fetch quite a high price at the scrap yard. The catalytic converters that got stole off the HGV's at our work had a value of £800!Catalytic converters work by having the heated gases react with the precious metals in the catalytic converter. There is platinum palladium and rhodium in a catalytic converter all three are very expensive and rare metals. Because of the honeycomb shape of the catalytic biscuit there is a lot of surface area for the gas to be neutralized on.Prior to catalytic converters being on every car for every mile you drove your car would punch out somewhere around 100g's of pollution. After the addition of catalytic converters with platinum and palladium this number dropped to less than 1g of pollution per mile. After the addition of rhodium it dropped N/E which is non detectable.
I don't know about the catalytic converter (typically Rangers -at least the 4.0L V6 has 2 catalytic converters). But for the rest of the exhaust system : with 2 prebend pipes, gaskets and the muffler, you are looking at anywhere from $ 361 to $ 457.00 as of Dec 15, 2011. - it also depends on the shop who does the work. Hope this helps.
The Koyote converters only work with the Windows operating system. There are numerous such converters available for the Mac.
YES - It can, but it is illegalWhile it might be illegal, let's not provide FALSEanswers based on legality on Answers.com.Better Gas MileageSince catalytic converter removal allows for exhaust gases to exit a car's engine at increased speeds, engine back-pressure is reduced, which lessens engine strain. This reduction in engine back-pressure and engine strain enables an engine to work more easily, and thus reduces fuel consumption and increases gas mileage. Lower Engine Operating TemperatureSince removing a catalytic converter lessens the burden on a car's engine by enabling engine exhaust to vacate the engine more easily, a net effect is a reduction in engine operating temperature. The more easily an engine functions and the less work it has to do results in less friction, less load and, ultimately, a lower operating temperature. More Fuel OptionsCars equipped with catalytic converters run only on unleaded gasoline. Lead-based gasoline, which produces more power and better engine combustion, quickly destroys the inner catalyst materials of catalytic converters. A car with no catalytic converter will be able to run on a variety of lead-based and/or high-performance fuels that would not be possible with a catalytic converter. Healthier Exhaust SoundCatalytic converters operate like car mufflers, whose sole purpose is to muffle the sound of exiting engine exhaust gases. Although catalytic converters burn unburned exhaust gases exiting an engine, thus making tail pipe emissions cleaner, they also further muffle a car's exhaust sound and bestow a somewhat timid, tempered exhaust sound. Without a catalytic converter, a car's exhaust sound becomes a little louder, a little deeper and more distinctive.
In the chemical industry and the industrial research, catalysis play an important role.The different catalysts are in constant development to fulfill economic, political and environmental demands.When using a catalyst it is possible to replace a polluting chemical reaction with a more environmental friendly alternative. Today, and in the future this can be vital for the chemical industry.The catalysts could help in accelerating chemical reactions and/or making it possible at lower temperatures.
They will still work with no converters. The O2 sensor downstream from the catalytic converter is there to monitor the function of the converter its self. So if you remove the converter, the second sensor will trigger the "check engine" light. The sensors (and the entire engine its self) is not effected, however. The light is basically just telling you the converter is no longer working, which is no surprise if it has been removed.
