What is EGR Valve, What Does It Do?

One of the most important parts of gasoline and diesel engines is the EGR valve. The EGR valve is found in almost all internal combustion engines, and manufacturers cannot even design an engine without an EGR valve. It has a great contribution to the low emission values, which are now becoming important. For this reason, the EGR valve is indispensable and what is the EGR valve and what does it do? The question is being asked more and more. As Izmir Adnan Menderes Airport car rental company, 5s CarRental, what is the EGR valve and what does it do? We wanted to inform you about it. So what is the EGR valve, what does it do?

EGR stands for Exhaust Gas Recirculation. Due to its usefulness, the EGR valve is a part that companies that carry out business such as Izmir Adnan Menderes Airport car rental will also want to have in their vehicles. The purpose of the EGR valve is to ensure that up to 6% of the exhaust gas ejected from the cylinders is mixed with the clean air over the intake manifold and returned back into the cylinders. The engine brain will decide the amount of use of the exhaust gases. Recently, electronically controlled EGR valves are used.

What Happens When The EGR Valve Is Broken?

What is the EGR valve described above, what does it do? After the question, what will happen if this valve is broken will also puzzle their minds. Since the EGR valve is constantly exposed to the passage of some exhaust gas, it gets dirty due to soot accumulated over time. Due to this contamination, blockage or narrowing may occur in the channel through which the gas passes. In this case, companies that carry out business such as Izmir Adnan Menderes Airport car rental and personal vehicle owners will also need to be aware of the following results, as they may cause significant problems:

• Fuel consumption increase
• Increasing emission values
• Increase in engine operating temperature
• Engine fault light comes on
• Irregular idle speed
• Jerky and jostling engine running
• Permanent damage to the engine as a result of using it in this condition for a long time.
• Shaking at accelerations and loss of performance

One or more of the above symptoms may occur at once. If it is the opposite of clogging and the EGR valve remains open all the time, a large amount of exhaust gas will enter the cylinders. Thus, the combustion will not be as it should be and problems similar to clogging will occur in the engine. Therefore, the valve should work neither more nor less, to the exact extent that it is adjusted. So what is the EGR valve, what does it do? Those who are curious about the answer to the question will also need to be aware of this setting. The owner of a personal car who has these problems or the company that rents a car at Izmir Adnan Menderes Airport should seek help immediately.

As explained above, soot accumulation is possible in the channel through which the exhaust gas passes. This causes the pipe to become dirty and clogged. If the soot in the mentioned channels is cleaned, the valve will become usable again. However, as a result of the long-term stay of the institution in these channels, the dirt may harden and petrification may occur. Even a small amount of this calcification may prevent the valve from working properly. If the valve is disassembled, it is absolutely necessary to change the gasket. Otherwise, what is the EGR valve, what does it do? Such questions will not matter and the valve will become unusable.

In fact, when the EGR valve is canceled, there is no significant effect that rasps the performance. However, in case of cancellation of this valve, it is not correct to cancel the EGR valve, as there is a possibility that the vehicle will not pass the exhaust inspection. Personal car owners and companies that do business such as Izmir Adnan Menderes Airport car rental should be aware of these results and pay attention.
