Method and device for reducing intake noises and mechanical vibrations in slot-controlled 2-cycle internal combustion engines

摘要

The invention relates to a method and an apparatus for reducing to a minimum the predominant full load noise of port-controlled, two-stroke internal combustion engines by constructing the lower suction port boundary and the lower piston boundary, so that there is a gradual port opening during the upward movement of the piston and a gradual port closing during its downward stroke.
