发明名称 Intake arrangement
摘要 An intake arrangement ( 1 ) for a two-stroke engine includes an intake channel ( 2 ) in which a throttle flap ( 3 ) is pivotally journalled with a throttle shaft ( 4 ). Downstream of the throttle flap ( 3 ), a partition wall ( 8 ) is mounted on the intake channel ( 2 ) and this partition wall partitions the intake channel ( 2 ) into an air channel ( 6 ) and a mixture channel ( 7 ). In the idle position ( 5 ) of the throttle flap ( 3 ), at least one fuel opening ( 14 ) opens into the mixture channel ( 7 ) downstream of the throttle flap ( 3 ). A connecting opening ( 16 ) between the air channel ( 6 ) and the mixture channel ( 7 ) is provided between the partition wall ( 8 ) and the throttle shaft ( 4 ) in the idle position ( 5 ) of the throttle flap ( 3 ). A shield ( 20, 30 ) is mounted in the mixture channel ( 7 ) between the fuel opening ( 14 ) and the connecting opening ( 16 ) in order to achieve a good swing performance of the two-stroke engine. The shield reduces the passing of fuel into the air channel and therefore the degree of wetting of the air channel with fuel.
