EGR Valve
The recirculation of exhaust gases or recirculation of flue gases or recirculation of exhaust gases (in the context of alternative internal combustion engines) consists in recirculating a “small” part (5-15%) of the exhaust gases by making them pass through the exhaust manifold to the intake manifold, in order to reduce a part of the pollutants present in the exhaust gases.
To obtain this recirculation of the burnt gases, during the final phase of the exhaust and the initial phase of the intake, a special solenoid valve or hydrovalve is used, the Exhaust Gas Recirculation (EGR) which is controlled by the engine control unit via a Pulse Width signal. Modulation (PWM – pulse width modulation) allowing the regulation of the quantity of exhaust gases from the related manifolds, which are recirculated in the intake manifolds and sucked into the engine. Together with the exhaust gases, the circuit also picks up the gases coming from the crankcase through the PCV, due to filtering through the piston rings and the evaporation of the engine oil.
