Exhaust Gas Recirculation (EGR) is commonly used to reduce NOx environmental emissions. It involves redirecting a controllable amount of engine exhaust back into the air.
The flow of these waste gases is primarily controlled by a valve, which can be partially or fully closed at each end.
By substituting burnt gases with oxygen-rich air, the number of available cylinders for combustion can be reduced.
This exchange also reduces the rate at which the cylinder retains heat, affecting NOx emissions. The presence of inert gas in the cylinder helps dissipate heat more slowly.
To effectively redistribute gases, an EGR cooler is recommended. It helps lower the gas temperature and ultimately affects the overall cylinder charge temperature. The benefits of using an EGR cooler include:
– Reduced charge temperature while lowering the peak temperature of the cylinder.
– Increased efficiency of the Exhaust Gas Recirculation System in the truck.
When the EGR technique is used, some inert gas is transferred into the vehicle cylinder, while some toxins are released into the environment. This process helps reduce the heat generated during combustion.
Recent studies on diesel engines show that EGR removal can, to some extent, reduce nitrous oxide emissions. However, it may increase the amount of smoke expelled from the exhaust pipe, which can positively and negatively affect the vehicle’s health.
Typically, an engine recirculates unused gases by transferring them from the exhaust manifold to the inlet manifold. This gas transfer pattern is known as external EGR. The EGR Valve within the circuit monitors and regulates the gas flow in the engine.
In some engines, a camshaft with a significant overlap is used, where the intake and exhaust valves are open simultaneously.
During the exhaust stroke, the exhaust gas within the cylinder is trapped, with a portion of it not expelled into the external environment.
At HGV Remapping, we provide advanced EGR solutions to our clients. Excessive carbon buildup on valves can cause blockages and decrease engine performance.
When the situation worsens, it can lead to code errors and sluggish car movements. Our software is designed to optimise engine performance and effectively clear valve blockages.
Although replacing the EGR system can be expensive, it is advisable to do so promptly. Failure to replace the EGR system on time can lead to severe carbon buildup and engine failure.
Our EGR removal service provides the following benefits:
– Increased power.
– Enhanced fuel efficiency.
– Improved throttle response.
– Reduction in flat spots.
– Cleaner intake system and engine.
– Lower maintenance costs.
– Prolonged engine and turbo life.
