Abstract of the Disclosure An internal combustion engine comprises a carbure- tor, which precedes an intake passage, at least one cylinder, a piston movable in said cylinder, intake and exhaust valves and igniting means. A flow-guiding element extends in said intake passage and defines therein a flow passage which tapers along said intake passage toward the intake valve so that the velocity of flow of the fuel-air mixture flowing in said flow passage will be progressively increased. The flow-guiding element may consist of a funnel-shaped tubular member or of a flow-guiding strip. The smaller end of the tubular member is disposed close to the intake valve and near that side of the intake passage on which said igniting means are disposed relative to the intake valve. Near its end opposite to the intake valve, the tubular member has a projection, which constricts another flow passage, which surrounds the tubular member in said intake passage. The flow-guiding strip gradually approaches the boundary wall defining the intake passage on that side thereof on which said igniting means are disposed relative to said intake valve.
