摘要： A four-cycle engine is provided that includes an exhaust port for releasing combusted gas from the engine and an exhaust system. The exhaust system includes an exhaust pipe coupled with the exhaust port, a first catalyst, a second catalyst, and a secondary air introduction pipe. The first catalyst is disposed in the exhaust pipe and the second catalyst is disposed in the exhaust pipe a set distance downstream of the first catalyst. The secondary air introduction pipe is configured to introduce air into the exhaust pipe. The secondary air induction pipe is connected to the exhaust pipe between the first and the second catalysts at a location where a temperature difference of the first and the second catalysts in a cold start transient phase is within a predetermined range.

摘要： Vapors normally arising within a standing gasoline tank are captured in a charcoal filled cannister. When the engine is running, air is drawn through the cannister thereby purging gasoline adsorbed on the charcoal within the cannister and delivering the purged gasoline vapors to the carburetor ultimately for combustion within the engine. Interference by the presence of such accumulated gasoline vapors in the carburetor, particularly during warm restarts and idling, can be avoided by preventing the injection of these gasoline vapors into the carburetor at the inappropriate times. Selective withholding of the purged gasoline vapors from a piston type carburetor, having a piston throttle valve disposed into and out of a venturi portion of the carburetor, is accomplished by injecting the gasoline vapors into the venturi portion through a purge port within the carburetor at a point such that the leading edge and outside surface of the piston type throttle valve closes and seals the port when the throttle valve is in a fully closed position. Thus, during idling and warm restarts, when the throttle valve is closed, no evaporated vapors are allowed to fill the venturi portion of the carburetor. Purging of the gasoline adsorbed on the charcoal within the cannister is accelerated by increasing the effective area of the purge port as the throttle valve is opened.
摘要翻译：通常在站立的汽油罐中产生的蒸气被捕获在一个充满炭的罐中。当发动机运行时，空气通过罐抽吸，从而清除吸收在罐内的木炭上的汽油，并将净化的汽油蒸汽输送到化油器以最终在发动机内燃烧。通过防止在不合适的时间将这些汽油蒸气注入化油器，可以避免在化油器中存在这种累积汽油蒸汽的干扰，特别是在暖重启和空转期间。通过设置在化油器的文丘里部分内的具有活塞节流阀的活塞式化油器选择性地扣留清除汽油的蒸汽是通过汽化器内的吹扫口将燃料蒸汽注入文丘里管部分而实现的使得当节流阀处于完全关闭位置时，活塞式节流阀的前缘和外表面关闭并密封端口。因此，在空转和暖启动期间，当节流阀关闭时，不允许蒸发的蒸气填充化油器的文氏管部分。通过在打开节流阀时增加吹扫口的有效面积，可以加速吸附在罐内的炭上的汽油的清洗。

摘要： A four stroke internal combustion engine has a gas reserving chamber 100 which communicates with an exhaust port 31 and is configured to reserve burned gas discharged from a combustion chamber. The burned gas flows into the gas reserving chamber 100 while an exhaust valve including a valve head 32a and a stem 32b is opened in an expansion stroke. The burned gas reserved in the gas reserving chamber 100 is discharged to the combustion chamber while the exhaust valve is opened in an intake stroke.

摘要： An internal combustion engine and method for operating the engine wherein a leaner than stoichiometric air/fuel ratio is maintained under all running conditions. The desired torque curve is obtained by increasing the amount of boost generated to the intake air charge without enrichening the air/fuel mixture. In addition, an anti-knocking system is incorporated that avoids knocking by retarding the spark advance and, at the same time, providing a leaning in the air/fuel mixture.

摘要： An improved induction system for a V type engine that is tuned for substantially all running conditions and which is nevertheless compact in construction. The system includes a pair of plenum chambers each disposed adjacent one of the cylinder heads of the engine. Each cylinder head has at least two intake passages serving the respective cylinder bores and a first conduit extends from the adjacent plenum chamber to one of the intake passages and a second conduit extends from the other of the plenum chambers to the other intake passage. A throttle valve arrangement is also incorporated so that good performance is achieved under all running conditions. The plenum chambers communicate with each other as their opposite ends to improve airflow and a common inlet opening serves each plenum chamber inlet.
