摘要： An internal combustion engine has an integral cylinder head, a one-piece connecting rod, and a crankshaft disposed at the interface between the first engine housing and the second engine housing. In an overhead cam shaft embodiment, the cam shaft drive means includes first and second gearsets of cross-helical gears. Also directly mounted to the cam drive shaft are the oil slinger, the centrifugally-responsive speed governor components, and the auxiliary power take-off shaft. This arrangement eliminates the need for additional shafts and subassemblies. In another embodiment, both the crankshaft and the cam shaft are disposed at the interface between the two engine housings to decrease manufacturing and assembly costs. The crankshaft and/or cam shaft bearings are formed integral with the engine housings to eliminate the need for separate bearing components.

摘要： A cylinder head and valve train mechanism for an internal combustion engine having six valves per cylinder. There are provided four intake valves and two exhaust valves. In some embodiments, the size of the intake valves is varied because they are served by a common port so as to insure equal flow to the cylinder through all valves. In one embodiment, a single insert forms two of the valve seats. Also, two of the four valves are disposed at acute angles to both a plane containing the cylinder bore axis and a perpendicular plane passing through this axis in many embodiments. In these embodiments, the cam lobes that operate the angularly disposed valves have cam surfaces that are inclined relative to the axis of rotation of the camshaft. In some embodiments, all of the intake valves are operated by a single camshaft. In other embodiments, two camshafts operate different pairs of the intake valves. Various bearing arrangements for the camshafts are illustrated and described.

摘要： In an internal combustion engine with cylinders inline and an overhead camshaft for actuation of the intake and exhaust valves, the camshaft is driven from the crankshaft by means of a driving gear and an intermediate shaft, the driving gear being rigidly connected to an outer cheek of the crankshaft. With this arrangement the distance between the crankshaft bearings remains unchanged and a minimum overall length of the engine is achieved. At the same time a speed reduction gear may be located anywhere between the crankshaft and the camshaft.

摘要： This specification discloses apparatus for locking and retracting the timing chain(s) or belt of overhead cam internal combustion engines. The apparatus consists of essentially two components; an adjustable Retractor and a spring loaded Lock. During maintenance and/or overhaul of the engine and following removal of the Rocker Arm Cover(s), the Lock is compressed and installed between the two sides of the timing chain and seated on top of the crank sprocket. Upon release, the spring of the Lock forces the two sides of the lock to expand and lock the timing chain into position around the crank timing chain sprocket and prevents the engine mounted timing chain tensioner piston from jumping out of detent and falling into the engine oil pan. Utilization of the Lock in the foregoing manner allows for the removal of the engine head which contains the overhead cam and upper timing sprocket without necessitating the removal of the engine front cover, fan, and oil pan. Following removal of the engine head the Retractor is installed at the front of the engine block using two of the engine head bolts to secure the Retractor in position on the two front head bolt holes of the engine block. The cam sprocket is then installed on the Retractor and the Retractor adjusted to tension the timing chain. Upon tensioning of the timing chain, the Lock may be removed, chain tension now being sufficient to maintain the engine mounted timing chain tensioner piston in position and the timing chain secure around the crank sprocket.
摘要翻译：本说明书公开了用于锁定和缩回顶置凸轮内燃机的正时链或带的装置。该装置基本上由两部分组成：一个可调节的收缩器和弹簧加载的锁。在发动机的维护和/或大修以及拆卸摇臂盖之后，锁被压缩并安装在正时链的两侧之间并且位于曲柄链轮的顶部。释放后，锁的弹簧迫使锁的两侧将正时链伸展并锁定在曲轴正链链轮周围的位置，并防止发动机安装的正时链张紧器活塞跳出制动并落入发动机油泛。以上述方式使用锁定装置可以拆卸包含顶置凸轮和上定时链轮的发动机头，而不需要拆卸发动机前盖，风扇和油底壳。在拆下发动机头后，使用两个发动机头螺栓将牵引器安装在发动机缸体的前部，以将牵引器固定在发动机缸体的两个前头螺栓孔上。然后将凸轮链轮安装在收缩器上，并且收缩器被调整以张紧正时链条。在正时链条张紧的情况下，可以拆下锁定件，现在链条张力足以将发动机安装的正时链条张紧器活塞保持在适当位置，正时链条固定在曲柄链轮周围。
