EGR stands for exhaust gas re-circulation, a vehicle emissions control concept used in both gasoline and diesel engines. The EGR valve, which works differently depending on how old the car is and whether it uses gasoline or diesel fuel, is a key component to a car’s exhaust system and engine health.
Pros and Cons of EGR Blocking or Delete:
EGR is an emission control devices developed by car manufacturers, which functions to redirect a portion of exhaust gas to the engine intake. As the function of EGR is to reduce engine efficiency for emission standards, it also lowers the engine life too. So it is a common practice to block off EGR valve to improve the quality of the vehicle.
First let us talk about the Pros of blocking EGR valve:
Blocking the EGR will regain the engine efficiency to its peak available. This means less fuel is needed to maintain the same power available from the engine.
As the engine efficiency is altered to best by blocking the carbon dioxide gas re-entering the engine, it gets better power on pistons at lower RPMs. RPM stands for revolutions per minute, and it is used as a measure of how fast any machine is operating at a given time. In cars, RPM measures how many times the engine’s crankshaft makes one full rotation every minute, and along with it, how many times each piston goes up and down in its cylinder. Yo do not have to work on the gears much to overtake and maneuver in city traffics.
As the EGR is blocked, the carbon soot and particulates get away from re-entering the engine. This makes the engine manifold, pistons and other components clean. A clean engine runs better and gets more working life compares to the one with more carbon particulates circulating in the engine.
Carbon soot acts as an abrasive material and increases wear and tear on the moving components. When EGR blocks, the engine gets to work in its peak efficiency, this makes a proper combustion in each cylinder and burns the fuel properly.
As fuel burns efficiently, there will not any unburnt fuel escaping the engine. This lowers the production of smoke from the engine. As more clean air is inhaled by the engine, a slight touch in accelerator pedal will give enough power to meet your demands. This puts a smile on your face and makes easier in city driving to overtake other cars.
Blocking the EGR will reduce the production of carbon soot as it burns fuel properly with plenty oxygen rich air. This avoids early blocks in DPF and catalytic converter.
Now let us see the Cons of deleting EGR:
As the purpose of EGR is to reduce the emissions in the car, as its blocked might see lesser carbon soot but it increase production of NOx, Carbon monoxide, and more which are harmful to the environment.
Blocking the EGR will increase the efficiency of the engine. This means, burns the fuel properly. As a proper and energetic combustion can slightly increase the engine sound and vibration. As the EGR is blocked, the combustion temperature increases. This increased burning temperature can make a knocking noise.
Affects Turbo Charged Vehicle:
When the EGR is blocked, more exhaust gas with higher temperature has to go through the turbo charger, making it to work harder and reduces its life to short side.
Blocking the EGR improves the engine efficiency, which means the fuel is burning at higher temperature. This makes the engine run hot. Sometimes the rubber seals and plastic casings cannot withstand such higher temperatures causing it to damage.
Problems with the modern cars:
Most modern cars have the advanced sensor systems to govern the EGR and gas properties. Newer cars get, oxygen sensors, EGR flow meters, gas temperature sensors etc, to keep an eye on the EGR system. If EGR is blocked, the ECM detects the block and activates limp mode followed by warming the driver with a check engine light. You may get the low end torque from the engine but the power will be restricted.
So these are Prosand Cons for EGR Delete or Blockinghope that will be helpful for you. If you have some more questions, just leave me a message, and I am happy to communicate. See you.
