  • Method and device for reducing harmful gas emissions from a motor vehicle internal combustion engine
    Patent number: 5836151
    Abstract: According to the invention, during a phase in which the engine is cold-started, the mechanical power supplied by the engine (1) to an auxiliary (23) is reduced by comparison with that normally absorbed by the auxiliary in normal operation. When this auxiliary is an alternator, the reduction in the power supplied by the engine, and therefore the slightest pollution which accompanies it, may be obtained by reducing the excitation current (i) of the alternator, under the control of a computer (11).
