Abstract

An internal combustion engine having an intake channel for supply of fuel and combustion air, and divided over a portion of its length into a mixture channel, and into a supply channel for supply of largely fuel-free air. A simple manufacture of the engine and a simple construction are achieved if a portion of the intake channel is guided in an elastic intake adapter, whereby the intake adapter has a partition that extends over at least a portion of the length of the intake adapter and divides the intake channel into a mixture channel and a supply channel.
