摘要： A breather device disposed in a timing-gear chamber of an engine includes an oil separator rotatable with a camshaft, and a tubular breather housing that removes the oil mist by working in cooperation with the oil separator. The oil separator has a plurality of fins arranged annularly around an axis line of the camshaft at fixed intervals. The tubular breather housing has openings in a periphery wall thereof and surrounds the oil separator.

摘要： A blow-by gas introducing passage having a blow-by gas inlet port, an air-cleaner-side breather passage that extends upwardly as branched from the blow-by gas introducing passage so as to communicate with an intake system, and a case-side breather passage that extends downwardly as branched from the blow-by gas introducing passage so as to communicate with an oil chamber are provided to an inner surface of a side cover that is detachably mounted to a timing-gear chamber communicating with a crank chamber. The blow-by gas introducing passage, the air-cleaner-side breather passage, and the case-side breather passage are formed integral with the side cover.

摘要： When an engine is operated at a low and medium speed range, since the combustion pressure introduced into a pressure chamber of a valve drive unit is relatively small, a control valve is projected toward the cylinder by the biasing force of a spring so as to lower the upper edge of the exhaust port. At the same time, in conjunction with this motion of the control valve, a resonance chamber is opened so as to communicate between the resonance chamber and the exhaust port, thereby the engine power is increased. When the engine is operated at a high speed range, since the combustion pressure is relatively large, the control valve goes away from the cylinder so as to enlarge the exhaust port and at the same time, in conjunction with this motion of the control valve, the resonance chamber is closed, thereby the engine power is increased.
摘要翻译：当发动机在低速和中速范围下运行时，由于引入阀驱动单元的压力室的燃烧压力相对较小，所以通过弹簧的作用力使控制阀向气缸突出，从而降低排气口的上边缘。同时，结合控制阀的这种动作，共振室被打开，以便在共鸣室和排气口之间连通，从而增加发动机功率。当发动机在高速范围下工作时，由于燃烧压力相对较大，所以控制阀离开气缸，从而扩大排气口，同时结合控制阀的运动，共振室关闭，从而发动机功率增加。
