ABSTRACT:
An induction system for supplying air-fuel mixture to a two-stroke cycle crankcase compression engine is disclosed. The induction system includes an induction passage for each crankcase compartment, and a reed valve system disposed between the induction passage and the crankcase compartment. The reed valve system includes a reed block having a plurality of valve ports, with the ports being arranged in oppositely spaced sets. The ports are preferably arranged so that the ports in one set are radially opposite the ports in the other set. A single reed valve member is disposed between the induction passage and the crankcase compartment for normally closing the valve ports. The single reed valve member includes a series of petals extending outwardly from a central portion, with a section of reduced area therebetween for reducing the stiffness of the reed valve member. A flow modifying body is disposed upstream of the reed valve system for directing the air-fuel mixture into the ports as it flows through the induction passage.
