Exhaust Heat Recirculation. The key to exhaust heat recirculation is a device called an exhaust gas recirculation (EGR) valve. The EGR valve opens when it encounters back pressure from the car's exhaust and channels it back into the combustion chamber.You might wonder what good this does, since the air in the chamber is mixed with gasoline to make it combustible.Well, one thing it does is to make the fuel warmer.xhaust Heat Recirculation.

An Inspiring Place. Glencar Waterfall is situated 11 kilometres west of Manorhamilton near the county boundary with Sligo. The waterfall is 15 metres (or 50 feet) high and its stream flows into Glencar Lough. Although not the largest waterfall in Ireland, it is one of the most beautiful. On days when there is even a slight breeze, the falling water is blown upwards into a graceful plume of steam-like spray. Hence its original name 'srut i n-agaid an aeir' which means 'the stream against the air'.
