ABSTRACT:
Partial load control apparatus and method for internal combustion engines with internal combustion in several engine working spaces, in which with a decreasing load the number of working strokes with internal combustion is reduced per time unit; for that purpose an increasing number of the working spaces are changed-over to an after-expansion operation which includes a number of displacement and after-expansion cycles divisible by two, whereby the working gas which has only incompletely expanded in the non-changed-over working spaces during a respective working stroke with internal combustion, is fed to the changed-over working spaces in lieu of a fresh mixture and is further expanded within these changed-over working spaces.
