摘要： The invention relates to a camshaft for a small internal combustion engine used in for example cars or motorbikes, it is characterized by being divided into two or more components, preferably it is the camshaft bearing journals (3) on the camshaft that are separate components. With a camshaft in one piece the camshaft lobes (4) cannot have a larger radius than the camshaft bearing journals (3) if the camshaft is to be inserted through the camshaft support bearings (2) in the engine. The bearing journals (3) will then limit the design and height of the camshaft lobes (4). By designing the camshaft divided in separate components to be assembled at the same time or after the camshaft has been inserted into the engine, it is possible to insert the camshaft radially displaced through the camshaft support bearings (2). This makes it possible to design the camshaft lobes (4) larger than what would otherwise be possible for given dimension of the support bearings (2). The invention relates to designs where the joining of the camshaft components are made by a joint in the axial center of the camshaft to minimize the influence on the outer dimension of the camshaft. This is extra important on small camshafts divided into separate components, where the design can have a large impact and limit the intended advantages with the design if not done right.
摘要翻译：本发明涉及用于例如汽车或摩托车的小型内燃机的凸轮轴，其特征在于被分成两个或更多个部件，优选地是凸轮轴上的作为分离部件的凸轮轴轴承轴颈（3）。如果将凸轮轴插入发动机中的凸轮轴支撑轴承（2），凸轮轴成一体，则凸轮轴凸角（4）不能比凸轮轴轴承轴颈（3）具有更大的半径。轴承轴颈（3）将限制凸轮轴凸起（4）的设计和高度。通过将凸轮轴设计成分开组装在同一时间或在凸轮轴插入发动机之后，可以将凸轮轴插入通过凸轮轴支撑轴承（2）径向位移。这使得可以设计凸轮轴凸角（4），大于对于支撑轴承（2）的给定尺寸否则将是可能的。本发明涉及这样的设计，其中凸轮轴部件的接合由凸轮轴的轴向中心处的接头制成，以最小化对凸轮轴的外部尺寸的影响。这对于分为独立部件的小型凸轮轴是非常重要的，其中设计可能会产生很大的影响，并且如果没有做出正确的设计，则会限制设计的预期优势。

摘要： Method for treating a crank pin (4) of a crank shaft (1). In the method hardness of the crank pin (4) surface is measured and when the hardness is over a predetermined limit value, depth of the hard spot (10) is measured. Heat treatment parameters are determined at least on the basis of the depth measurement and the hard spot (10) is heat treated. During the heat treatment the hard spot (10) is heated by an induction heating device (5).

摘要： The invention relates to methods and means of regulating the speed of a two-stroke combustion engine. An arrangement for alternating an ignition timing relative to a top dead center position is provided. For a given engine speed, the ignition timing may be step-wise adjustable. One or more steps may be used while alternating between two ignition timings. The ignition timing may be adjusted when the engine speed increases above a threshold engine speed.

摘要： A crankcase scavenged two-stroke engine (1) comprises a cylinder (15) including scavenging ports (31, 31') and at least one exhaust port, a piston (13), a connecting rod (17), a crankshaft (18) and a generally sealed crankcase (16). The crankcase inducts a fuel/air mixture and is connected to the scavenging ports (31, 31') by means of transfer ducts (3, 3') which, as the piston (13) is travelling from a lower position towards a higher position, are inducting pure air let in from connecting ports (8, 8') near the scavenging ports (31, 31') in the cylinder (15). The transfer duct (3, 3') volume is less than 20 % of a volume swept by the piston (13) during an entire revolution of the crankshaft (18). Recesses (10, 10') are formed in an outer periphery of the piston (13), said recesses (10, 10') co-operating with the connecting ports (8, 8') in the cylinder wall for controlling the filling of the transfer ducts (3, 3') with air. An inlet tube (22) in the cylinder wall supplies the air/fuel mixture, said inlet tube (22) being connected to the crankcase (16) and covered by the piston (13) as the piston (13) is in the lower position, and open to the crankcase (16) as the piston (13) is in the higher position.
