Title:
MOTOR COMPRISING AN AIR ADMISSION CIRCUIT FOR OPTIMISING THE VOLUMETRIC EFFICIENCY
Document Type and Number:
WIPO Patent Application WO2006045986
Kind Code:
A3
Abstract:
The invention relates to a supercharged motor (10) comprising an admission circuit (20) provided with at least two charge air coolers (22, 24) arranged in parallel respectively on a primary branch (B1) and a secondary branch (B2) of the admission circuit (20), each branch (B1, B2) comprising an upstream line (26, 28) and a downstream line (30, 32) which are respectively adjacent at the inlet and the outlet of the cooler (22, 24). Said motor is characterised in that the upstream (26, 28) and downstream (30, 32) lines are connected two-by-two and provided with valves (46, 48) which are controlled according to the rotational speed of the motor (10) in such a way as to optimise the volumetric efficiency of the admission circuit (20).
