Abstract:
PURPOSE:To improve function of multi-cylinder engine by arranging a solenoid valve in the way of a tube coupling between one end of hole communicating through downstream of respective throttle valves and the upstream of the throttle valve. CONSTITUTION:Balance holes 8, 8' are made between communication holes 9, 9' and throttle bodies 1, 1' in order to absorb rattling of shafts 5, 6 and fixing error of throttle valves 2, 2', 3, 3'. A collection tube 10 is added to the balance holes 8, 8' and a solenoid valve 11 is arranged at the upstream side. Bypass air quantity is controlled with open valve time interval of the solenoid valve 11. Consequently, response and output are improved, resulting in improvement of engine function.
