摘要： An intake system for a rotary piston engine having a plurality of engine sections, each engine section being separated by an intermediate housing. In the intake system, there are provided communicating passages for communicating the engine sections so that intake air can be transferred between working chambers formed in the engine sections in accordance with a difference in rotor phase between the engine sections. The communicating passage is located so as to be closed after an intake port is closed in each engine section and positioned so that there remains a larger amount of intake air in each of the working chambers than the minimum amount of intake air required for ensuring idling rotation speed under idling engine operating condition when the communicating passage is closed. This intake system makes it possible to obtain a rotary piston engine which can remarkably reduce pumping loss and desirably control the amount of intake air in accordance with an engine operating condition.

摘要： An internal combustion engine is provided with a fuel injection valve. The fuel injection valve is actuated so that fuel injected therefrom reaches the combustion chamber in the latter half of the intake stroke, thereby accomplishing stratified charge. The timing at which blow-back of intake gas occurs is detected and the timing for terminating fuel injection is advanced as the timing at which blow-back of intake gas occurs becomes earlier.

摘要： An intake system for an internal combustion engine comprises a first valve provided to open and close an intake passage leading to each combustion chamber, a bypass passage for introducing intake air into each combustion chamber bypassing the first valve, and a second valve provided to open and close each of the bypass passages. The first valves are operated to close the respective intake passages in a light load range and to open the same in a heavy load range. The second valve is operated to close the bypass passage in the middle of each intake stroke. The first valves are controlled so that the opening of the intake passages is increased as the engine load increases after exceeding a predetermined value, and the second valve is controlled to delay the time the bypass passage is closed with increase in the engine load so that the time the bypass passage is opened overlaps with the time the intake valve is opened when the engine load reaches the predetermined value.

摘要： An engine intake system includes a combustion chamber, a first intake port opening to the combustion chamber, and a second intake port opening to the combustion chamber. A shut-off valve is provided for blocking intake gas flow to the combustion chamber through the second intake port in a first engine operating region wherein engine load is relatively small, and allowing the intake gas to flow to the combustion chamber through the second intake port in a second engine operating region wherein the engine load is relatively large. A first valve actuating mechanism is provided for opening the first intake valve at a first timing, and a second valve actuating mechanism is provided for opening the second intake valve at a second timing. A valve timing changing device is provided for changing the first timing with respect to the second timing so that the first intake valve is closed later than the second intake valve in the second engine operating region, and so that the first intake valve is closed at least in a certain engine operating zone in the first engine operating region at a timing which is more advanced than the timing at which the first intake valve is closed in the second engine operating region.

摘要： A dual induction type intake system for an internal combustion engine has a primary intake passageway for light load operation of the engine and a secondary intake passageway for heavy load operation of the engine. The downstream side open end of each intake passageway opens toward the intake port of the cylinder of the engine. The secondary intake passageway is provided with a controllable valve therein. The load on the engine is detected and the controllable valve is opened when the load on the engine is heavier than a predetermined value so that the intake gas is introduced into the combustion chamber through both the primary and secondary intake passageways, while otherwise the controllable valve is closed so that the intake gas is introduced into the combustion chamber only through the primary intake passageway. The primary intake passageway has a flat cross sectional configuration with its longer axis extending substantially in parallel to the lower end surface of the cylinder head, and at the same time the primary intake passageway is throated by narrowing its width, as measured in the horizontal direction, from upstream toward downstream in the direction of the flow of the intake gas. The downstream side open end of the primary intake passageway is offset from the center of the cylinder bore.
摘要翻译：用于内燃机的双感应式进气系统具有用于发动机的轻负载运行的主进气通道和用于发动机的重负载运行的二次进气通道。每个进气通道的下游侧开口端朝向发动机气缸的进气口开口。次级进气通道在其中设置有可控阀。检测到发动机上的负载，并且当发动机上的负载比预定值重时，可控阀打开，使得进气通过主进气通道和次级进气通道被引入燃烧室，否则可控阀被关闭，使得仅通过主进气通道将进气引入燃烧室。主进气通道具有扁平的横截面形状，其长轴基本上平行于气缸盖的下端表面延伸，并且同时通过使水平方向测量的主要进气通道变窄而使主入口通道变窄，从进气的流动方向的上游向下游。主进气通道的下游侧开口端偏离气缸孔的中心。
