Abstract
An improved intake system for an internal combustion engine is disclosed which includes a combustion chamber, an intake passage and an exhaust passage opening to the combustion chamber, and an intake valve and an exhaust valve disposed in the intake and exhaust passages for opening and closing thereof. The system is featurized by provision of one or more control passage(s) opening to the intake passage in the vicinity of the intake valve, and a supply chamber of a predetermined volume which is in communication with the control passage(s). The system is particularly effective in improving the intake efficiency in small-sized, four stroke cycle engines.
