Abstract: A pump assembly is presented including a motor housing holding an electric motor and a wet-end housing. The pump assembly also includes a heat transfer interface positioned between a front end of the motor housing and the wet-end housing. The heat transfer interface establishes a thermal conduction path between the motor housing and the wet-end housing so that, in use, a portion of heat generated by the motor is absorbed by the heat transfer interface and is dissipated in water circulating through the wet-end housing. In addition, or alternatively, another thermal conduction path may be established between the heat transfer interface and an electronic controller of the pump assembly so that heat generated by the controller is absorbed by the heat transfer interface and dissipated in water circulating through the wet-end housing.

Abstract: A method of controlling elements used to execute the elementary functions of internal combustion engines. The method controls the elements using measurement signals provided by sensors, determines theoretical signals that have to be provided by reference sensors at a current operating point of the engine, determines deviations between the theoretical signals and the signals measured by the reference sensors, and establishes signal correction instructions for the elements according to the determined deviations.
