In an air intake system (14) for a multi-cylinder combustion engine (1) a bypass system (31, 32, 33, 34, 35) is provided which is connected upstream and downstream of the throttle valve (20) to the air intake passage (16). The bypass system comprises a pressure regulating tank (3), valves (33) controlling communication between the tank and each one of the air intake passages downstream of the throttle valve and a single valve (35) controlling communication to one of said air intake passages upstream of its throttle valve. The invention provides for a simple and inexpensive air intake system to stabilize combustion and to supply air according to the operating conditions of the engine, in particular when the throttle valves are closed. |
