    Abstract: A continuous variable valve timing with an intermediate lock pin and includes a camshaft, with a cam that protrudes from the camshaft, configured to lift a valve. In addition, a variable device is disposed at one side of the camshaft with a retarded angle chamber and an advanced angle chamber disposed therein. An oil control valve is configured to supply the retarded angle chamber or the advanced angle chamber with hydraulic pressure to retard or advance the rotation of the camshaft, respectively. Furthermore, a cam position detector is configured to detect a rotation position of the cam. A controller is configured to detect a signal of the rotation position of the camshaft from the cam position detector and vary a frequency of a PWM duty configured to operate the oil control valve, when a variation characteristic of the signal of the rotation position exceeds a predetermined range.

    Abstract: A system for continuously varying valve-opening overlap in reciprocating internal combustion engines changes the path of the timing belt (16) that drives the intake valve camshaft (26). An idler wheel (44) mounted on a pivoted arm (48) turns against the timing belt. At low engine speeds, the sprocket wheel idles against the timing belt. At higher engine speeds, increased engine oil pressure causes a hydraulic cylinder (58) to force the sprocket wheel against the timing belt, changing its path. As the path of the belt is changed, the intake valve position is advanced with respect to the position of the crankshaft (12). The exhaust valve position remains the same relative to that of the crankshaft. Thus at above-idle speeds, intake-exhaust valve overlap is present. Since the amount of belt path deviation is related to engine oil pressure, and thus engine speed, valve overlap varies smoothly as a function of engine speed. A tensioner (30) maintains proper belt tensioning at all times.

    Abstract translation: 在往复式内燃机中连续改变阀门重叠的系统改变驱动进气门凸轮轴（26）的同步皮带（16）的路径。 安装在枢转臂（48）上的惰轮（44）相对于同步皮带转动。 在低发动机转速下，链轮与同步皮带空转。 在较高的发动机转速下，增加的发动机机油压力导致液压缸（58）迫使链轮抵靠同步带，改变其路径。 随着皮带的路径改变，进气门位置相对于曲轴（12）的位置前进。 排气阀位置相对于曲轴的位置保持不变。 因此，在怠速速度下，存在进气排气阀重叠。 由于皮带路径偏差量与发动机机油压力有关，因此与发动机转速有关，因此阀重叠作为发动机转速的函数平滑变化。 张紧器（30）始终保持适当的皮带张紧。

    Abstract: In accordance with the invention, an internal combustion engine having reciprocating piston sleeves is realized comprising an engine block with a pair of cylinders, each cylinder having an intake port, an exhaust port and two linearly opposing pistons connected to two opposing crankshafts. A pair of piston sleeves are reciprocatingly mounted in each cylinder, one piston sleeve around each piston. Each piston sleeve is connected to one of two eccentric shafts that run parallel and adjacent to each crankshaft. The piston sleeves have ported slots in communication with either the intake ports or the exhaust ports of each cylinder. The eccentric shafts are mechanically connected to the crankshafts such that they move in unison.
