An internal combustion engine has a rotatable work shaft, a crank connected with the work shaft, a plurality of cylinders having working chambers, a plurality of pistons movable in the cylinders, and connecting means connecting the pistons with the crank so that a gas pressure in the combustion chambers applied to the pistons is transmitted when a maximum pressure is obtained in the combustion chambers and a maximum lever arm of the crank is obtained so as to provide a maximum torque on the work shaft.
