Abstract
An internal combustion engine has a casing and a piston arrangement including a piston coupled to a track. The track is coupled to a shaft and has an inner cam surface and an outer cam surface. The piston is coupled to the track by followers which run on the respective inner and outer cam surfaces of the track to control motion of the piston. A sliding element is connected to the piston and extends below the piston head having a profiled slider surface which engages a corresponding profile in the casing. Also, the casing includes at least two plates having a cutout for receiving the track and a bore for receiving the shaft, and at least two end plates coupled transverse to the plates. At least one cylinder bore is formed in the end plates, and the piston is arranged to move in reciprocating motion in the cylinder bore.

An internal combustion engine comprising:
- a piston arrangement including a piston coupled to a track, wherein the track is coupled to a shaft and has a cam surface, and the piston has a follower which runs on the cam surface of the track to control motion of the piston;
- a casing, wherein the casing comprises at least two fin plates having a cutout for receiving the track and a bore for receiving the shaft, and
- at least two end plates coupled transverse to the fin plates;
- wherein at least one cylinder bore is formed in the end plates, and the piston is arranged to move in reciprocating motion in the cylinder bore, and
- wherein the fin plates are arranged in abutment, wherein the piston comprises a piston head arranged outside the at least two fin plates and within the at least one cylinder bore of one of the at least two end plates.
A method of assembling an internal combustion engine comprising a casing and a piston arrangement including a piston coupled to a track;
- wherein the track is coupled to a shaft and has an inner cam surface and an outer cam surface, and the piston is coupled to the track by followers which run on the respective inner and outer cam surfaces of the track to control motion of the piston;
- wherein a sliding element is connected to the piston, the sliding element extending below the piston head and comprising a profiled slider surface which engages a corresponding profile in the casing, and the followers are mounted on the sliding element;
- wherein the casing comprises at least two fin plates having a cutout for receiving the track and a bore for receiving the shaft, and at least two end plates, wherein at least one cylinder bore is formed in the end plates, and the piston is arranged to move in reciprocating motion in the cylinder bore;
- the method including the steps of:
- coupling the piston arrangement to the shaft by coupling the track to the shaft and coupling the piston to the track;
- bringing the at least two fin plates together into abutment on either side of the track;
- and bringing the end plates together so as to be transverse to the plates;
- and coupling the end plates to the fin plates, wherein the piston comprises a piston head arranged outside the at least two fin plates and within the at least one cylinder bore of one of the at least two end plates.
