Four-stroke combustion piston engine comprises a cylinder (13), a piston (14) and a crank housing (1). The cylinder chamber is subdivided by the piston into a top cylinder chamber (ZO) and a combustion chamber (HR). The piston has at least one inlet valve allowing gas transfer between the top cylinder chamber and the combustion chamber. The combustion chamber is defined by the piston base, cylinder wall and the cylinder base and has at least one outlet valve in the region of the cylinder base. Preferred Features: At least one air inlet valve (22) for sucking in fresh air is arranged in the top cylinder chamber.
