Abstract: A starting strategy for a power train of a motor vehicle including an internal combustion engine fitted with a drive shaft extending along a longitudinal axis, an alternator-starter, a first pulley that is designed to be driven in rotation by the drive shaft, a pulley that is rigidly connected to a shaft of the alternator-starter, a belt encircling said two pulleys, and a coupling/decoupling system between the first pulley and the drive shaft of the engine, characterized in that the starting strategy includes a preparation procedure for said belt in cold weather.

Abstract: A starting strategy for a power train (10) of a motor vehicle including an internal combustion engine (11) fitted with a drive shaft (12) extending along a longitudinal axis (X), an alternator-starter (14), a first pulley (15, 19) that is designed to be driven in rotation by the drive shaft, a pulley (16) that is rigidly connected to a shaft of the alternator-starter, a belt (17) encircling said two pulleys, and a coupling/decoupling system (18) between the first pulley (19) and the drive shaft of the engine (12), characterized in that the starting strategy includes a preparation procedure for said belt in cold weather.

Abstract: An internal combustion engine including: an even number of inline cylinders, each accommodating a piston; a crankshaft rotatably mounted about an axis; first and second balance shafts rotatably mounted about balancing axes parallel to and separate from the engine axis; and first and second mechanisms for rotating the first and second balance shafts at rotating speeds that are dependent on a rotating speed of the crankshaft. The balancing axes of the first and second balance shafts coincide, and the second rotating mechanism adjusts a phase difference between angular positions of the first and second balance shafts around the balancing axis.

Abstract: A control method for an internal combustion engine including an exhaust gases post-processing system and a system for recirculating the exhaust gases towards the intake, wherein the engine can be switched from a regeneration operation mode with throttling to a nominal mode without throttling. At the end of the engine operation in the regeneration mode, the engine is temporarily operated in an intermediate mode with partial throttling for limiting the contrast of the intake noise.
