摘要： An internal combustion engine has a cylinder liner arranged in the cylinder. A piston moves reciprocatingly in a direction of the longitudinal cylinder axis in the cylinder and is guided within the cylinder liner across a section of a movement path of the piston in the cylinder. A combustion chamber disposed in the cylinder is delimited by the piston. In a crankcase, a crankshaft is rotatably supported by a crankshaft bearing, wherein the crankshaft is driven in rotation by the piston about an axis of rotation of the crankshaft. A position of the cylinder liner relative to the crankcase is secured with form fit by a securing element located at an end face of the cylinder liner that is facing the crankcase. No loads are transmitted into the cylinder liner from the crankshaft bearing through the end face of the cylinder liner that is facing the crankcase.

摘要： A pair of suction-side scavenging ports introduces a working gas containing fuel into a combustion chamber, and the working gases are caused to collide with each other to thereby form a working gas layer in a state of two vortexes rotating in opposite directions to each other, and a pair of exhaust-side scavenging ports introduces a non-working gas having a lower fuel content rate than the working gas into the combustion chamber, and the non-working gases are caused to collide with each other to thereby form a non-working gas layer in a state of one vortex.

摘要： A machined shape of a bore is based on the deformation amount of a data-acquisition bore after fastening of cylinder head. A cross section of an approximate shape is set to be an approximately-true circle shape, and a diameter of the approximately-true circle shape is changed along a central axial direction in accordance with the deformation amount of the data-acquisition bore, to determine the approximate shape. The approximate shape has a cross section having the approximately-true circle shape and has a simple shape which is symmetrical about the central axis. Since the machined shape of the bore is the shape obtained by reversing a phase of a recess and a projection of the approximate shape about a predetermined cylindrical shape, the machined shape has a cross section having the approximately-true circle shape and has a simple shape which is symmetrical about the central axis.

摘要： A liquid-cooled engine provided with cooling means for cooling an area surrounding a combustion chamber using a cooling liquid cooled by a radiator and caused to flow through a cooling passage. The cooling passage is embedded inside a cylinder block and a cylinder head. The cooling passage is formed in a continuous fashion such that the cooling liquid is introduced from the radiator to cool an area surrounding the combustion chamber, and thereafter returns to the radiator by looping around an area surrounding an exhaust valve for opening and closing an exhaust port of the combustion chamber.
