| Exhaust gas recirculation cooler - assembly overview |
| t
| The exhaust gas recirculation system is fitted with a radiator using coolant to improve the emission values. |
| t
| Under certain operating conditions, the exhaust gases that have passed through the combustion chamber are directed to this radiator. In this way, the temperature of the exhaust gases is reduced thus reducing the temperature in the combustion chamber and improving the emission values. |
| t
| The engine control unit decides when the gases must be directed through the radiator. By means of the exhaust gas recirculation radiator change over valve -N345- the control unit activates a vacuum chamber, which in turn activates the change over valve for the recirculation of gases. |
