摘要： Various embodiments provide a method of varying engine displacement. The method includes determining a change in a stroke distance of the engine required to obtain a pre-determined volumetric change in a displacement of the engine. The method includes machining a top surface of a crankcase so as to remove a height of material from the crankcase. The height is calculated to correspond to the change in the stroke of the engine required to obtain the volumetric change in the displacement of the engine. The method also includes coupling the crankcase to an engine block portion of the engine.

摘要： A two-cycle engine (10) includes a crankshaft (13) that has shafts (17, 18) on both sides and a crankcase (12) that pivotally supports the shafts (17, 18) of the crankshaft (13) through bearings (21, 26). A collar (29) is circumferentially provided on an outer ring of one of the bearings (26) that supports one of the shafts (18) on a side at which a low load is applied. The crankcase (12) is provided with an inserting portion (24) into which the one of the bearings (26) is inserted. The inserting portion (24) penetrates the crankcase (12) while keeping a constant diameter. An engaging portion (27) with which the collar (29) is engaged from an inner side is provided in an inner portion of the inserting portion (24).

摘要： A four-stroke engine includes a case (1) which is comprised of a first case half (3) and a second case half (8) connected with each other at a parting plane which goes through centerline of a crankshaft and is perpendicular to centerline of a cylinder (7). A first bearing seat (19) is divided into a first upper bearing seat half (4) and a first lower bearing seat (9) at the parting plane. A second bearing seat (20) is divided into a second upper bearing seat half (5) and a second upper bearing seat half (10) at the parting plane. The first upper bearing seat half (4) and the second upper bearing seat half (5) are integrally molded on the first case half (3), and the first lower bearing seat half (9) and the second lower bearing seat half (10) are integrally molded on the second case half (8). An outer side surface of the first case half (3) and a side cover (21) form a valve-operating chamber (26) for receiving a valve-operating mechanism (30).

摘要： A bearing cap (11) fastened to a bulkhead (2) of a cylinder block (1) by bolts to support a crankshaft. A pair of protruding parts (25, 26) that enlarge a joint surface (12) between the bearing cap (11) and the bulkhead (2) in a transverse direction of the crankshaft are formed respectively in a pair of side surfaces (33, 34). A pair of reinforcing parts (35, 36) are positioned between a top surface (19) and the pair of protruding parts (25, 26), protrude from the pair of side surfaces (33, 34) in the transverse direction of the crankshaft, and have a protrusion length that is smaller than that of the pair of protruding parts (25, 26). The stress on the joint portion between the bearing cap (11) and the bulkhead (2) generated by the crankshaft during operation of the internal combustion engine is thereby reduced.

摘要： The invention relates to a method for producing a ventilation bore (1) in a thrust bearing (2) of a crankcase (3) of a reciprocating internal combustion engine by milling, wherein the milling cutter (4) is an angled head milling cutter, which is introduced into the crankcase (3) in the direction of a cylinder longitudinal axis (Z) and is moved in the direction of a crankcase longitudinal axis (K) until the thrust bearing (2) is perforated and subsequently the angled head milling cutter is moved back in the direction of the crankcase longitudinal axis (K) and removed from the crankcase (3) by moving the angled head milling cutter in the direction of the cylinder longitudinal axis (Z). Internal stresses in the crankcase are avoided by the production according to the invention of the ventilation bore, as a result of which the strength of the crankcase is advantageously increased.
