<p>An internal combustion engine and method for operating the same wherein the combustion chamber volume can be varied depending on throttle position by a member (9) that is inserted into the combustion chamber, and wherein the intake valve (34) is closed before the piston (32) completes its intake stroke so that the expansion stroke is effectively lengthened. In the case of a two-stroke engine, some of the intake gas is expelled before combustion to achieve an effective lengthening of the expansion stroke.</p> |
