What is an egr solenoid?
The EGR system was created to reduce combustion temperatures, which reduces the engine’s emissions. This system uses a valve to recirculate exhaust gas from the crankcase back to the intake manifold to be re-burned.FunctionAn EGR solenoid controls whether or not exhaust gases get recirculated into the intake manifold.ProblemDuring high power needs, EGR systems reduce an engine’s horsepower by diluting the air fuel mixture.The SolutionIn order to prevent engine power loses during high power needs, a solenoid was added so the car’s on-board computer can turn the EGR system on and off.EffectsThis change increased the engine’s horsepower and still allowed the engine to meet emission requirements.LocationThe solenoid replaced the internal components of the EGR valve.
