摘要： A piston (10) defines a combustion recess which has an opening and at least one chamber having an opening into the combustion recess. The piston comprises a body portion (12) which defines a socket (20) and has a central surface (12c) within said socket defining a portion of said combustion recess. The body portion (12) also has a chamber-defining surface (12d) which extends around said central surface. The piston also comprises a generally annular portion (14) which is received in said socket (20). The portion (14) has a surface (14e) which cooperates with said central surface (12c) in defining the combustion recess, and a chamber-defining surface (14f) which overlies the chamber-defining surface (12d) of the body portion. The chamber-defining surfaces (12d, 14f) cooperate in defining said chamber, and said opening to the chamber is defined by a groove (24) in one of said chamber-defining surfaces.

摘要： A camshaft (10) is manufactured by forming a plurality of individual cams (12) and mounting them on a shaft (20). Each cam has a groove (16) formed in a bounding surface of a shaft-receiving hole (14) thereof and the cam is held in position by means of a key (30; 40) which is received in the groove (16) and engages a flat (22) formed on the exterior surface of the shaft (20).

摘要： Cams for mounting on a shaft are manufactured by assembling a stack of dies (10) with frangible members (12) interposed therebetween. The dies (10) define cam-shaped cavities (24) and the frangible members (12) define restricted orifices (32) interconnecting the cavities (24). The cavities (24) are filled with molten metal through the orifices (32). After the metal has solidified, and removal of the dies (10), the frangible members (12) are broken away and the cams are separated by breaking through the sprues defined by the orifices (32).

摘要： A piston (10) containing a cavity (16) is manufactured by forming a box (20; 50; 70; 80). The interior of the box defines the cavity (16). The box is mounted in a die cavity (26) and the piston is cast around the box. The box is provided with projections (22c; 24c; 52; 58; 73) which enter recesses in the wall of the die cavity and support the box. After removing the piston from the die cavity, the projections are machined off.

摘要： A four-stroke internal combustion engine having, per cylinder, first and second inlet valves (6, 7) and first and second exhaust valves (10, 11) has a bifurcated part of the inlet port leading individually to each inlet valve, and a bifurcated part of the exhaust port leading individually from each exhaust valve. The first inlet valve and the first exhaust valve are actuated by cams (14, 16) having timing profiles suited to low and medium engine speeds. The second inlet valve and the second exhaust valve are actuated by cams having timing profiles suited to higher engine speeds. The flow of intake charge to the second inlet valve, and the flow of exhaust gases from the second exhaust valve, are controlled by the settings of two valves (56, 60) in the inlet and exhaust ports being changed in unison. The control valves are opened either at a particular engine setting, or over a range of engine settings.
摘要翻译：四冲程内燃机，其中与每个气缸的第一和第二进气门（6,7）以及第一和第二排气门（10,11）相关联，并且其中分叉进气口甚至单独地从每个排气阀单独地通向每个进气阀和排气口的分叉部分。第一个进气门和排气门由凸轮（14,16）控制，其同步曲线适合于低速和中速发动机。第二个进气门和排气门由凸轮控制，其正时曲线适应更快的发动机速度。通过位于排气口中的两个阀（56,58）的同时调节来控制进入第二进气阀的进气流量和来自第二排气阀的排气流量。进气和排气。控制阀在特定的阀门设置或一定范围的发动机设置下打开。
