Abstract
The main objectives of new technologies for internal-combustion engine are lower consumption, pollutant reduction and comfort passenger increase. To reach these objectives, we have adopted for engine thermal management two strategies: quicker rise temperature during the cold start and higher engine temperature for part load. To satisfy these criteria, we have modified the classic cooling loop. An electric water pump, an electric water valve and variable speed fan system are the new actuators automatically controlled by electronic calculator. This concept allows to obtain a warm-up time reduced by 50% and 2 to 3% fuel economy on the European cycle.
