Internal combustion engine e.g. heat engine, fuelling system for motor vehicle, has electric motor regulating units with control board having input and output ports provided with connection units that are compatible with each other

摘要

The system has a fuel pump (36) driven by an electric motor (34), and electric motor regulating units. The electric motor regulating units have a control board (24) with input and output ports (E, S) provided with connection units allowing a connection of the board between a battery (37) and the motor. The connection units are compatible with each other. An independent claim is also included for a method to control fuelling pressure of an internal combustion engine.
