EGR System - Gasoline: Description

The Exhaust Gas Recirculation (EGR) system recirculates exhaust gases into the combustion chamber to reduce combustion temperatures. The reduction in temperature acts to reduce oxides of nitrogen (NOx) emissions.

On Maxima, 300ZX and 300ZX Turbo, the EGR system is controlled by the ECCS control unit. The system consists of EGR Control Valve, EGR Control Solenoid Valve, Throttle Valve Switch, Cylinder Head Temperature Switch and Crank Angle Switch.
