EGR (Exhaust Gas Recirculation):

Environmental rules on the manufacturing of lower-consumption automobiles and higher vehicle emission requirements are becoming increasingly stringent, while numerous procedures and technologies to minimize emissions have been created, and EGR is one of these technologies. This brief article explores EGR technology.

Nitrogen oxides’ function in air pollution:

Exhaust emissions contain a variety of contaminants, with nitrogen oxides (NOx) being the most serious environmental dangers. Diesel engine exhaust pollution components include carbon monoxide, sulfur dioxide, soot particles, unburnt hydrocarbons (UHCs), and nitrogen oxides.
Exhaust gas regeneration (EGR) is one of the primary options for decreasing diesel-induced pollution levels. Its primary function is to reduce nitrogen oxide levels in automotive engine emissions, particularly diesel engines, as much as feasible.

Nitrogen oxide formation:

The highest temperature in diesel engines at the combustion peak and in the flame center varies from 1800 to 2100°C, and in petrol engines from 850 to 1400°C, resulting in an active bonding between nitrogen and oxygen molecules.

Given the conditions for the formation of nitrogen oxides and the impossibility of preventing nitrogen from entering the engine, the best preventative measure is to control the composition conditions by lowering the combustion chamber temperature.Obviously, lowering the combustion temperature has implications since it reduces output power by preventing the maximum energy of the fuel from being released. As a result, if power output must be maintained, more fuel should be burned in each cycle. The amount of additional fuel required to get identical power from two similar engines with and without EGR will vary between %2 and %10.

Controlling the temperature of the combustion process:

Now that we’ve discussed and realized that NOx, as one of the main families of engine pollutants, is formed at ultra-high combustion temperatures, the ideal preventative measure for reducing pollutants appears to be lowering the engine’s combustion temperature, which is difficult because combustion occurs instantaneously. As a result, certain treatments, such as cooling the cylinder body, are ineffective in lowering the combustion temperature.

One way to lower combustion temperature is to diverge the engine’s input air, which is possible by recirculating some of the exhaust gas to the engine.

The quantity of oxygen in the combustion chamber is restricted when some of the exhaust gas enters the engine inlet and, as a result, the combustion temperature decreases. EGR is built on this technique. The amount of exhaust gas returned is determined by the engine round per minute, the amount of residual oxygen in the exhaust smoke, the ambient temperature, the engine temperature, and the ambient height.

As previously stated, EGR should be able to reduce combustion temperature; however, due to the high temperature of the exhaust gas, if the engine’s output gas directly returns to the combustion chamber, it will not only not reduce the temperature, but will also raise it. As a result, a cooling system is built in the route of the gas flow to reduce the temperature of the exhaust gas before it is recirculated into the manifold, reducing the chance of overheated gas entering the engine.

In some circumstances, we are forced to tweak EGR using ECU control maps or turn off the EGR in order to improve performance or minimize fuel consumption.

The advantage of EGR delete/off

1. Throttle Response Improvements

2. Lower Maintenance Costs

3. Runs smoothly and effectively, resulting in decreased fuel usage.

4. Engine components are still clean.

5. Longer engine and turbo life means less oil contamination.

6. DPF failure prevention measure
Engine temperature has been reduced.

Disadvantages of Using an EGR Delete Kit: Using an EGR delete kit has certain disadvantages.

1. An rise in exhaust gas temperature (EGT) may occur in the engine.

2. In the United States, streetcars are not permitted to employ these KITs. You will fail the emission testing required by your state.

3. It may cause your engine to bang.

4. Only off-road trucks are permitted.

We at DPF deleteshop have years of expertise in ECU calibration and remapping and can thoroughly identify and optimize EGR-related tables in all  diesel ECUs. Resetting EGR maps or EGR REMOVAL in DPF deleteshop may be accomplished using a variety of approaches.

Below are 2d and 3d pictures of EGR control tables in three pieces of ECM software: Swiftec, WinOLS.

How much does an EGR deletion remap cost?

The cost of  EGR  Delete varies depending on the vehicle, and at DPF deleteshop, we can perform it for you at the lowest possible cost while providing guarantee and assistance.

Delete DPF

The DPF is one of several technologies that are used to minimize air pollution. The performance of the DPF system is determined by its capacity to absorb particulate matter (soot).
DPF failure can be caused by a high mileage vehicle, EGR valve issues, poor performance tuning, and other factors.
In such cases, a large amount of particulate matter might build and choke the exhaust gas path out of the engine. You may delete DPF, however you must adjust the ecu software thereafter. Removing the DPF software is permanent and painless, which is a significant benefit that will eliminate DPF clogging and blockage, as well as the associated difficulties and expenditures.
