Suffer

The suffer caused by some good intentions to improve some situations is to be seen in any case. For example, Exhaust Gas Recirculation(EGR) emission control system on the vehicle is so designed to cause incomplete combustions by inletting some amount of exhaust gas leading to burning at lower temperature. The purpose is reduction of poluting emission gas.Then, what'll happen if this dirty exhaust gas circulation is stopped by some method ? Naturally the burning temperature rises up and cooling liquid temp also up, leading to high utilization rete of electric cooling fan, following the lack of charging in lead battery is the result.
