摘要： An engine idle and speed control arrangement incorporating a butterfly-type throttle valve. The throttle valve is disposed so that it is at a relatively small angle to a plane containing the throttle valve axis and extending perpendicular to the direction of air flow through the induction passage. The peripheral edge of the throttle valve is configured so as to avoid binding. Bypass idle air flow is provided around the throttle valve as to provide substantially the entire idle air speed requirements of the engine. This arrangement permits better idle control since the idle air-flow changes will be more uniform in response to given angular changes in the position of the throttle valve.

摘要： A number of embodiments of feedback control systems for two-cycle, internal combustion engine management systems. Each embodiment employs an exhaust system sensor which senses the exhaust gases by drawing exhaust gases from the exhaust of the engine. In some instances this is done directly from the cylinder and in others it is done in the exhaust system. In each embodiment, the sensor is provided in an accumulator chamber so as to provide an accurate signal of instantaneous engine running conditions. The use of the accumulator chamber insures that the combustible gases will not be diluted with fresh air charge, but will be able to purge from cycle to cycle so as to provide cycle-by-cycle information. Various arrangements are provided for protecting the sensor element including serpentine flow paths, shields, the direction in which the exhaust gases are delivered, lubricant catalysts, conduit shape, sensor cooling and combinations of these features. Furthermore, various structural elements help protect the exterior of the oxygen sensor from damage, such as housings, placement of the sensor within depressions in the engine and integrally forming the sensor in the cylinder block.

摘要： A marine drive includes an improved transmission and shifting mechanism to facilitate a smoother transition when shifting into a reverse drive condition. The transmission includes a positive clutch and a friction-type sub-clutch. The shifting mechanism desirably includes a shift cam with first and second cam surfaces. The first cam surface effects actuation of the positive clutch and the second cam surface effects actuation of the friction sub-clutch. The first and second cam surfaces are configured so that the shifting mechanism causes the friction sub-clutch to engage before the positive clutch engages. As a result, the instantaneous loading on an engine of the marine drive when shifting the transmission into reverse is reduced.

摘要： An outboard motor includes an improved engine layout to provide a compact power head while simplifying the arrangement of components on the engine. In one mode, an induction system of the engine includes a carburetor that is arranged over a cylinder head. An intake pipe connects the carburetor to an intake port of the cylinder head. The pipe has generally a U-shape and loops around the upper side edge of the cylinder head. An air intake device is arranged upstream of the carburetor to supply air thereto. The air intake device includes a downward facing air intake opening that is located along a side of the engine below the upper end. This arrangement of the induction system that extends over the upper side of the engine produces a compact assembly without overly complicating the arrangement of other components on the engine, such as, for example, a manual starter device. With the present engine layout, the manual starter device is positioned on an upper side of the engine in front of the carburetor near a crankshaft of the engine. The air intake opening faces a lower air vent formed in a cowling below the engine. Cool air flows through the lower air vent and is drawn into the air intake opening for engine operation. This flow of cool air also cools the engine. The cowling also includes an upper vent to expel warm air from about the carburetor on the upper side of the cowling and to promote a current of air across the engine for cooling purposes.
摘要翻译： 舷外马达包括改进的发动机布局以提供紧凑的动力头，同时简化发动机上部件的布置。 在一种模式中，发动机的感应系统包括布置在气缸盖上的化油器。 进气管将化油器连接到气缸盖的进气口。 该管通常具有U形并围绕气缸盖的上侧边缘环绕。 在汽化器的上游配置有进气装置，以向其供给空气。 进气装置包括向下的进气口，其位于发动机下方的上端的下方。 在引擎的上侧延伸的感应系统的这种布置产生紧凑的组件，而不会使发动机上的其它部件（例如手动起动装置）的布置过度复杂化。 根据目前的发动机布局，手动起动装置位于发动机的上侧，靠近发动机曲轴的化油器前方。 进气口面向在发动机下方的整流罩内形成的下部通风口。 冷空气流过下部通风口，并被吸入进气口进行发动机运转。 这种冷空气流也冷却发动机。 整流罩还包括一个上部通风口，用于从整流罩上侧的化油器周围排出温暖的空气，并促使空气流过发动机进行冷却。

摘要： A feed back control system and method for direct injected engines, particularly useful in marine applications to avoid knocking. Different types of injection control are applied to achieve this depending on the engine running condition when knocking occurs. Both injection initiation and duration are controlled. Injection timing is employed primarily to control knocking under steady state running. Both injection initiation and duration are controlled to avoid knocking under acceleration.

摘要： A start-up strategy for engine feedback control that utilizes a combustion condition sensor associated with only one cylinder. On starting and warm-up, only that one cylinder is feedback-controlled at all times. Under these conditions, the amount of corrected fuel supplied to the feedback cylinder is added to a fixed incremental amount of fuel that will be supplied to the remaining cylinders. This promotes smooth warm-up without backfiring or stalling and a quicker transition to all cylinder feedback control.

摘要： An improved and simplified outboard motor construction wherein the exhaust system for the engine is formed with a minimum number of components and sealing joints. The exhaust system includes an elongated expansion chamber formed in the drive shaft housing. In addition, the drive shaft housing has a cylindrical section that is journaled within a swivel bracket for its steering movement. The volume between the external portion of the drive shaft housing and the internal portion of the swivel bracket forms a second expansion chamber that is employed for the low speed above the water exhaust gas discharge. The flow of cooling the water to and from the engine is controlled so that the exhaust gas interchange area between the power head and the drive shaft housing will be well cooled, as will the oil reservoir for the engine.
