摘要： An induction system for a multi-valve internal combustion engine including a control valve arrangement for redirecting the flow into the combustion chamber through a relatively small displaced bypass passageway under certain running conditions so as to provide a high velocity flow into the combustion chamber even though the total air flow is small. The flow is also directed so as to generate a slant-type tumble motion in the combustion chamber to further increase the turbulence and improve combustion under the running conditions when the control valve is in its flow restricting flow redirecting position. The bypass passage has a relatively regular configuration with a low peripheral length to cross-sectional area ratio so as to provide a compact overall assembly and to facilitate manufacturing. In the open position, the control valve offers substantially no restriction to air flow so that high power outputs can be achieved while still maintaining good running under low-speed, low-load conditions.

摘要： An air intake system for an internal combustion engine uniformly distributes the fuel-air mixture in the cylinder, and concentrates the mixture in the vicinity of an ignition plug in the cylinder by selecting the direction of supply of sprayed fuel, thereby improving ignitability of the mixture at the time of lean-burn operation. The system produces tumble flow in the cylinder for accelerating combustion and provides lean-burn operation, thereby suppressing consumption of the fuel and reducing the amount of exhaust gas. The fuel is injected by a fuel injection valve and collides with an intake valve, before being atomized. The atomized fuel flows into the cylinder from the side of the intake valve closer to the fuel injection valve. On the other hand, high-velocity air flow from bypass passages enters the cylinder from the side of the intake valve closer to the ignition plug, so as to produce tumble flow in the cylinder.

摘要： A spark-ignited direct cylinder fuel injection engine is provided with a combustion chamber formed in a depression on the surface of each piston, and a direct cylinder fuel injection valve spraying a fuel mist directly in the combustion chamber. In the wall of the combustion chamber an arc-shaped first wall surface region is located on the upstream side of the combustion chamber with respect to the swirl flow direction of the intake air. Continuous with the first wall surface region, a straight second wall surface region is formed at the downstream side of the first wall surface region. An arc shaped third wall surface region is formed at the downstream side of the second wall surface region. A spark plug is positioned so that it protrudes into the depressed combustion chamber at the region near the second wall surface region when the piston is positioned at its top dead center. Fuel is injected into the first wall surface region part of the combustion chamber, and carried by the intake swirl flow toward the third wall surface region part of the combustion chamber while it is being diffused and vaporized. Therefore, when flowing along the second wall surface near the spark plug, the injected fuel forms an ignitable air-fuel mixture, thus stable ignition, by the spark plug, is obtained regardless of the amount of the fuel injected into the combustion chamber.
摘要翻译：火花点火的直列式燃料喷射发动机设置有形成在每个活塞的表面上的凹陷中的燃烧室，以及直接气缸燃料喷射阀，直接在燃烧室中喷射燃料雾。在燃烧室的壁中，弧形的第一壁表面区域相对于吸入空气的涡流方向位于燃烧室的上游侧。连续地具有第一壁表面区域，在第一壁表面区域的下游侧形成直的第二壁表面区域。在第二壁面区域的下游侧形成有弧形的第三壁面区域。火花塞被定位成使得当活塞位于其上止点时，其在靠近第二壁表面区域的区域处突出到凹陷的燃烧室中。燃料被喷射到燃烧室的第一壁表面区域部分中，并且当其被扩散和蒸发时，通过进气旋流流向燃烧室的第三壁表面区域部分。因此，当沿着火花塞附近的第二壁面流动时，喷射的燃料形成可点燃的空气 - 燃料混合物，由此可以获得通过火花塞的稳定点火，而与燃烧室中喷射的燃料的量无关。

摘要： In this ceramic engine, the cylinder liners are formed out of a ceramic material, and bearings consisting of a ceramic material are installed in the rotary sliding portions of a crankshaft and larger- and smaller-diameter parts of connecting rods, suction ports being formed in the cylinder liner lower portions so as to be spaced in the circumferential direction thereof, these suction ports and crank chambers communicating via first suction passages, fuel alcohol supply means being provided in second suction passages through which suction air is introduced into the crank chambers. Accordingly, lubricating films of ungasified components of the fuel alcohol are formed on the sliding surfaces of the pistons and cylinder liners and those of the above-mentioned rotary sliding portions, and these sliding surfaces and rotary sliding portions are kept in an excellently lubricated condition owing to such lubricating films. Moreover, the alcohol collected in the crank chambers and the alcohol constituting the lubricating films on the above mentioned sliding surfaces and rotary sliding portions are burnt in order, and suction air is supplied through a low-temperature portion of the engine. Therefore, the suction efficiency does not decrease, and the effciency of the engine can be improved.

摘要： A stratified-combustion internal combustion engine according to the present invention comprises at least two intake ports situated on one side of a combustion chamber, guide passages connected individually to the intake ports, a fuel injector disposed in one of the guide passages. Each guide passage has a straight region extending over a predetermined length from its corresponding intake port. Thus, an air-fuel mixture and air, guided by the respective straight regions of the guide passages to be supplied through their corresponding intake ports to the combustion chamber, flow along the axial direction of a cylinder bore, thereby forming barrel swirl flow separated in layers from each other.

摘要： At least one inlet channel (4) for each cylinder is developed as a filler channel in which there is a flap valve (13) turning on an axis (12). During full load operation, the flap valve (13) is in a rest position, which does not influence the flow through the inlet channel (4). During partial load operation, however, the flap valve (13) is in a working position, in which it shapes the flow in the inlet channel so unsymmetrically that at the mouth (6) of the inlet channel (4) leading into the cylinder (1) the compressed air flowing out in large quantities has a tendency toward spiral and/or turbulence-reinforcing directions. In this way, fuel preparation is improved during the partial load operation of the motor, leading to combustion with low smoke and noxious substance levels and low consumption.
