INTERNAL COMBUSTION ENGINE HAVING A STARTER DEVICE

摘要

An internal combustion engine has a supply channel for supplying combustion air. A throttle element is arranged in the supply channel. The engine has a starter device which enables a defined free flow cross section in the supply channel in a starting position. The starter device latches in the starting position and the latching is released by actuating an operator-controlled element. A first ramp controls the free flow cross section of the fuel port depending on the position of the throttle element. The free flow cross section of the fuel opening is controlled by a second ramp. The free flow cross section of the fuel opening, which is set using the second ramp, is greater than a flow cross section set using the first ramp for the same position of the throttle element. A favorable performance of the engine after starting thereof is achieved.

主权项

1. An internal combustion engine comprising:
an operator-controlled element; a supply channel for supplying combustion air for the engine; a throttle element mounted in said supply channel; said operator-controlled element being operatively connected to said throttle element to adjust the position thereof; a starter device having an operating position and a starting position; said starter device being configured to enable a defined clear flow cross section in said supply channel in said starting position; said starter device including an actuation unit for setting said starter device in said starting position thereof; a latching unit for latching said starter device in said starting position; said operator-controlled element being operatively connected to said latching unit for unlatching said latching unit in response to an actuation of said operator-controlled element; a fuel port having a free flow cross section and opening into said supply channel; a first ramp configured to control said free flow cross section of said fuel port in dependence upon the position of said throttle element when said starter device is in said operating position; a second ramp configured to control said free flow cross section of said fuel port in response to a first actuation of said operator-controlled element after said unlatching of said latching unit at least up to a closing operation of said throttle element following said first actuation of said operator-controlled element; and, said free flow cross section of said fuel port based on said second ramp being greater than a flow cross section adjusted for the same position of said throttle element based on said first ramp.
