Exhaust gas recirculation (EGR) is a emission control system found in many internal combustion engines, including those used in vehicles, power plants, and other applications. The purpose of EGR is to reduce the amount of harmful nitrogen oxides (NOx) emitted from the engine, which contribute to air pollution and can have negative health effects.

EGR means what? Exhaust Gas Re-circulation system.

How does EGR work?

EGR works by recirculating a portion of the exhaust gas back into the engine’s combustion chamber, where it mixes with the incoming air/fuel mixture. This reduces the peak temperature in the combustion chamber, which in turn reduces the amount of NOx formed during the combustion process.

EGR systems can be classified into two types: internal EGR and external EGR. Internal EGR is typically used in engines with high-pressure fuel injection systems, and involves routing a small portion of the exhaust gas back into the engine through the intake manifold. External EGR, on the other hand, is used in engines with low-pressure fuel injection systems and involves routing the exhaust gas through a separate passage to the intake manifold.

EGR Benefits

There are several benefits to using EGR in engines. In addition to reducing NOx emissions, EGR can also improve fuel efficiency and reduce the amount of carbon dioxide (CO2) emitted from the engine. It can also help to reduce the engine’s tendency to knock or ping, which can be caused by high temperatures in the combustion chamber.

EGR Drawbacks

However, there are also some drawbacks to using EGR. One of the main challenges is that the recirculated exhaust gas can contain soot and other contaminants, which can build up over time and clog the EGR system or affect engine performance. EGR systems also require regular maintenance and cleaning to ensure they are functioning properly.

In conclusion, exhaust gas recirculation is a useful emission control system that helps to reduce the amount of harmful NOx emitted from internal combustion engines. While it has some benefits, it also has some limitations and requires regular maintenance to ensure it is functioning properly.

EGR Deletes

An EGR delete is a modification to an exhaust gas recirculation (EGR) system that involves removing or disabling the system. EGR systems are used in many internal combustion engines to reduce the amount of harmful nitrogen oxides (NOx) emitted from the engine, which contribute to air pollution.

Some people choose to perform an EGR delete in order to improve the performance of their vehicle. Removing the EGR system can potentially increase horsepower and torque, as well as improve fuel efficiency. However, it is important to note that EGR systems are also used to reduce emissions, and removing the system may result in higher emissions from the vehicle.

EGR deletes are not legal in all areas, as they may violate emissions regulations. In some cases, performing an EGR delete may also void the manufacturer’s warranty on the vehicle. It is important to be aware of the laws and regulations in your area before considering an EGR delete.

Additionally, it is worth noting that EGR systems can be prone to problems, such as clogging or malfunctioning, which can affect the performance of the vehicle. If you are experiencing issues with your EGR system, it may be more appropriate to have it repaired or replaced rather than deleting it altogether.

Who makes these heavy duty diagnostic laptops?

The laptops are manufactured by Panasonic in Japan or Taiwan. Toughbooks are the number one choice for heavy duty mechanics. The downside? Panasonic charges crazy prices for them new, anywhere in the region $3000-6000 USD each! This is where I come in. Refurbished units are much more affordable, and cost only a fraction of new. I load them with fresh and latest software and put through rigorous testing to ensure they perform just like new! These are incredibly reliable MIL-SPEC units which can survive multiple drops and exposure to the elements. They can handle: heat up to +50C, cold up to -30C, rain, mud, dirt, sand, dust, oil, grime, and more! Just take a look at the torture test videos and prepare to be blown away. Furthermore, the higher end models have bright outdoor viewable displays. You can stop finally stop squinting!

Why buy a refurbished International diagnostic laptop Toughbook?

Panasonic Toughbooks are the strongest laptops in the world. They are a favorite of police & military forces around the world. The downside? High prices from the factory. These units cost as much as $3000-5000 USD! However, refurbished they are much more affordable. I supply a wide selection refurbished Toughbooks with a 6 months warranty. I customize both hardware and software to your precise needs! Please contact me if you got any questions or would like to order a unit.
