Abstract:
An internal combustion engine comprising:at least one combustion chamber for burning a fuel in timed explosions accompanied by formation of a combustion gas; at least one expansion chamber which is connected with the combustion chamber and separate from the combustion chamber and which has a piston for converting energy of the combustion gas into mechanical energy or work; and a cam gear unit by which a drive shaft is driven by the piston and which has a cam disk and associated thrust member, the thrust member being lifted from the cam disk; wherein when stroke pauses without ignition of fuel in the combustion chamber are inserted depending on the instantaneous output requirement, the piston of the expansion chamber remains at a top dead center and the thrust member of the cam gear unit remains lifted from the cam disk of the cam gear unit and the cam disk rotates past the thrust member in an unimpeded manner.
