Abstract
An internal combustion engine having a cylinder, a fuel-supply mechanism, and an elastic connector for connecting the fuel supply mechanism to the cylinder. The connector has a first channel for fuel/air mixture and a second channel for combustion air. The connector has a first connection end and a second connection end at which the two channels open out. The two channels are separated from one another by a partition that extends in the longitudinal direction of the channels. The partition is twisted about its longitudinal central axis between the first and second connection ends to achieve a great elasticity of the connector. To produce the elastic connector, a respective core is used for each channel, and the cores are moved relative to one another to enable removal of the connector from a mold.
