摘要

The engine has an inlet port divided into air-fuel mixture- and air- channels by a separating plate. A fuel flow guide unit (28) is arranged on a throttle`s side facing the port section lying upstream of the mixture channel, to increase speed of fuel flow in an area of a fuel opening. The unit is made of plastic and placed on a throttle`s section lying upstream of a throttle shaft, in a completely opened state of the throttle.
