The internal combustion engine comprises at least one set of three coaxially arranged cylinder chambers (3, 5, 7), sealed off from one another, and three pistons (9, 11, 13), connected to one another by a common piston rod (15), each of which is sealed off and displaceable in one of the cylinder chambers (3, 5, 7). The middle piston (11) divides the middle cylinder chamber (5) into two combustion spaces (17, 19). The two outer pistons (9, 13) define two precompression spaces (25, 27) in the outer cylinder chambers (3, 7). The maximum volume of the precompression spaces (25, 27) is greater than the maximum volume of the combustion spaces (17, 19). Between the precompression spaces (25, 27) and the adjacent combustion spaces (17, 19), rotary slide valve arrangements (29, 31) are provided, which control the inlet ports (33, 35) of the precompression spaces (25, 27) and/or the transfer ports (37, 39) and/or exhaust valves of the combustion spaces (17, 19). The precompression spaces (25, 27) may have a dead space (79, 81) and can be controlled so that the fuel/air mixture is first compressed in the precompression spaces (25, 27) and then expanded before it is fed into the combustion space. In this way the mixing of the mixture is improved. The internal combustion engine can in this case be designed as a two-stroke or four-stroke engine. The transfer ports can also be designed so that they ... Original abstract incomplete. <IMAGE>
