摘要

The engine has fuel vapor and blow-by gas reaspiration circuits (100, 200) comprising circulation channels (11, 21) separated into upper branches (12, 22) and lower branches (13, 23). The upper and lower branches are connected to an air intake circuit (700) in upstream and downstream of a compressor (62), respectively. The lower branch (13) of the reaspiration circuit (100) constitutes a portion (23``) of the lower branch (23) of the reaspiration circuit (200).
