STARTAUTOMATIKANORDNING FOR EN FORBRENNINGSMOTOR, I SYNNERHET FOR MOTORN I EN MOTORKEDJESAG

摘要

An automatic starting arrangement for a hand-started internal combustion engine is disclosed. Internal combustion engines of this type have a choke flap and a throttle flap positioned one behind the other in the air-intake channel. In order to ensure a reliable starting of the engine independently of manual positioning activities, the invention provides that in the starting operation, the choke flap initially moves independently of the throttle flap. The throttle flap is held in a half-throttle position between the full-throttle position and the idle position. Before the choke flap is brought into its at-rest no-choke position, a movable holding mechanism is actuated and the throttle flap is released.
