Here's Everything About Your Car's Emission Parts

Heard of this term but don’t know what it means or does? We have put it all together to help you understand and resolve any problem that may arise with it.

Pollutants like hydrocarbons, carbon monoxide, and oxides of nitrogen are released during the combustion of gasoline. The need to reduce the emission of these pollutants leads to introducing computerized control systems in the automobile sector. These modern-day computers use various sensors to collect data and can vary the function of an engine by controlling spark timing, fuel injection.

Further, many parts do not affect the performance of the vehicle but play their role in decreasing the release of harmful pollutants.

Emission parts are mostly near the exhaust manifold and the exhaust pipe. Part like catalytic converter is located just before the muffler on the exhaust pipe, oxygen and temperature sensor are near the catalytic converter. The air injection system is mounted in the exhaust manifold. Similarly, other parts like EGR (exhaust gas recirculation), PCV valve are near the engine.

Searching for some information about car emission parts? In that case, all you have to do is keep on reading further:

1. Catalytic Converter - One way to prevent the release of unburnt hydrocarbons or harmful monoxides into the environment is to provide an extra area for oxidation, this extra area is known as a catalytic converter. A catalytic converter has a honeycomb-like structure made of platinum or palladium; these two act like a catalyst. When exhaust gas passes over it, it gets oxidized and monoxides like carbon monoxide get converted to carbon dioxide.

2. Positive Crankcase Ventilation System (PCV) - PCV takes the vapours produced in the crankcase during combustion and mixes them with the intake air-fuel mixture so that vapours also get burnt. But by adding crankcase vapours the air-fuel mixture gets diluted, so the PCV system also meters the amount of vapours to be added to the mixture.

3. Exhaust Gas Recirculation Valve (EGR) - The purpose of an EGR valve is to recirculate a small amount of exhaust gas back into the intake air-fuel mix, this dilutes the mixture and helps reduce the temperature of the combustion chamber. But as we know our engine is not designed to run on exhaust gases, so the amount of exhaust gas that is mixed in the air-fuel mixture should be controlled very precisely.

4. Evaporative control - Gasoline evaporates very easily, earlier this evaporated gasoline was vented completely into the atmosphere, this caused pollution. In 1970 this was prohibited and an evaporative control system was installed in every car.

5. Air Injection System - To have combustion we require only three things: fuel, oxygen, and heat. In the exhaust manifold we have everything, some unburnt fuel and we surely have a lot of heat, the only thing left is oxygen. So, the air injection system introduces some air into the exhaust manifold. This ignites the unburnt fuel and prevents its release into the atmosphere.

Have a look at the features of car emission parts below:

Emission parts may or may not have any effect on performing your vehicle, but because of the rising pollution, we need to take as much care as possible to reduce our carbon footprint. The primary purpose of emission parts is to detoxify exhaust gases.

Few features to be kept in mind when we talk about our vehicle’s emission are, spark plug and valve timing, these both are controlled by ECU with the data provided by the oxygen sensor.

In modern-day cars, this function is performed with the help of various sensors and electronic controls. To understand the whole working of emission parts we will move step by step starting from the beginning.

Catalytic converter functions as extra space and a catalyst for further oxidation of the monoxides released during combustion. Air injection introduces oxygen in the exhaust manifold that starts with the combustion of unburnt fuel so that no hydrocarbons can escape into the environment. The Evaporative control system has a charcoal chamber that captures all the evaporated gasoline and when the engine starts, the engine's vacuum pump draws the vapours to be burnt in the engine. PCV and EGR capture the crankcase vapours and some exhaust gas respectively and mix them with the intake air-fuel mixture to reduce pollutant release.

There are various symptoms by which a vehicle owner/ driver can easily predict the problem with his vehicle’s emission parts. A few of the symptoms that help to get to know if any of the above-mentioned problems exist or are going to occur are:

1. Appearance of Error Code P0440

Sometimes there can be an appearance of emission control system indicator light or the check engine light. It might show that there is something wrong with your automobile. Code P0440 can start appearing on your dashboard, which shows that there is some issue with your car emission control sensor. Make sure that you get it checked by a professional so that he can make necessary corrections.

2. Consuming a lot of gas than usual

Is your car consuming a lot of gas than usual? If yes, then it means that there is some issue with your car emission control system and its related parts. It is important to get your car checked by a mechanic so that he can figure out which part is not working properly and solve this issue of your car burning through gas much more quickly than it did in the past.

3. There might be a lot of smell of fuel or gas inside or outside your vehicle

The odour of gasoline is difficult to ignore. If you smell it while your car is running or idling, pull over as quickly as possible and get it towed to the nearest service facility. Gas vapours are quite hazardous. They can give rise to the burning in the inside of your nostrils, cause headaches, nausea, and even vomiting. So get this problem solved by visiting a mechanic.

4. There might be a loss of performance

If you find out that your vehicle is not performing well, that it is a sign that there is some fault in your car emission control system. The emission control system is a very important car part that is connected to the complete fuel and exhaust system. So if there is any issue with the fuel system, pressure in the fuel system, or the air transfer systems, then it will give rise to the poor performance of your car.

Are you thinking of repairing your Emission Parts on your own? Then there is one thing you must have: the right tools needed for repairing your Emission Parts. It is essential to make sure that you are outfitted with the right tools to get the work done properly. Have a look at some tools which you might need to get started with your repair work:

Emission Parts replacement cost can differ widely depending on the application, the brand of the Emission Parts as well as who does the work. All you have to do is to replace your faulty Emission Parts with us online and then you can leave your car to the mechanic and pick it up a few days later. Just be sure that the car mechanic is highly skilled and has a good reputation. Sometimes the additional service level might cost you more than what you have expected. We also recommend you to take pictures of your car before you leave it with them so that you are sure that later on it is returned to you in an unharmed condition. New emission parts have a very vast range of costs depending on the parts. For example, an oxygen or temperature sensor is around $50-$110. Whereas some parts, like EGR valves, start from $80 and go to approximately $180. Replacing these parts can be a very basic task but some parts like EGR, air injection systems can be very tricky jobs.
