The Importance Of Catalytic Converters
Even though cars are convenient to use and has become part of our day to day lives. The rate of air pollution this creates is no doubt harmful to the environment. But these emissions are now controlled due to the integration of catalytic converter which reduces the amount of chemicals released.
The fuel and air are mixed in internal combustion engines. The mixture produces combustion which is used to power the vehicle the moment when spark plugs create ignition. The leftover in the process exits on valves and this process continues for thousands of times more. Some unused fuel in form of carbon monoxide and hydrocarbons as well as nitrogen oxide exits the car and cause air pollution. To make sure that the engine emissions are clean, less dangerous and safer for both the people and the environment is the job of catalytic converter. By using chemical reaction and energy, the catalyst is transforming some gases producing a more favorable result.
Catalytic converters have to change the harmful byproducts of combustion through oxidation process. Introducing oxygen on heated gases cause the CO and HC at the same time to become carbon dioxide and water which in a sense is less harmful. Catalyst has a thin layer of platinum and coating is applied on substrate material like honeycomb that’s made either of metal or ceramic. The small platinum atoms are binding the molecules tightly then the oxygen is introduced allowing the catalyst to work.
There are many different types of catalytic converters and among them is the 2-way converter that does the processes above. You may not believe it but since the mid 70s, this has been implemented to be used on cars to be able to address third byproduct which is NOx. As for 3-way converters, it’s designed and created with added step referred to as reduction. What this does is splitting NOx into oxygen and nitrogen. This is a real challenge but it’s been resolved by way of introducing oxygen between the oxidation and reduction stage to make it more efficient.

On the other hand, the fact that it requires certain temperature in order to process chemical reaction properly is what some people see as a setback of catalytic converters. To put it simply, the device is not going to work if the car is overheating and it will not work either in the first few minutes upon starting the car. Some other issues would be the road temperature as well as debris that may possibly cause damage to the converters so you must watch out for this when driving. But other than that, the device should work just fine.Doing Services The Right Way
