摘要： A configuration for a uniflow-scavenged, opposed-piston engine reduces exhaust cross-talk caused by mass flow between cylinders resulting from one cylinder having an open exhaust port during scavenging and/or charging while an adjacent cylinder is undergoing blowdown. Some configurations include a wall or other barrier feature between cylinders that are adjacent to each other and fire one after the other. Additionally, or alternatively, some engine configurations include cylinders with intake and exhaust ports sized so that there is an overlap in crank angle of two or more cylinders having open exhaust ports of about 65 crank angle degrees or less.

摘要： An exhaust apparatus for an internal combustion engine wherein an on-off gate valve and a driving source therefor are not required for each bypass pipe. The exhaust apparatus includes a plurality of exhaust pipes extending independently from each other individually from a plurality of exhaust ports. Bypass paths communicate the exhaust pipes with each other in a region wherein the exhaust pipes are independent of each other. The bypass paths are opened or closed to control an exhaust characteristic. A plurality of bypass paths are provided and a bypass joining section at which the bypass paths are joined so as to be positioned in parallel to and in the neighborhood with each other is provided. At the bypass joining section, a single on-off valve that opens and closes the bypass paths simultaneously, and a single actuator for driving the on-off valve to open and close are provided.

摘要： An exhaust pipe for two-stroke, internal-combustion engines in which there are multiple exhaust expansion chambers, each within one another, used in combination, the multiple chambers allow for the combustible fuel/air mixture to be delivered in more optimal reflective pressure waves throughout the RPM range of the engine. By changing the number of the chambers, their size and shape, the design of the exhaust pipe can be tuned for torque and power while requiring a minimum of space.

摘要： The present invention relates to a exhaust pipe structure with back-pressure controlling and fuel saving comprising: a barrel, with an inner tube; a back-pressure device, connected to said barrel, with a back-pressure pipe inside, said back-pressure pipe with one or more holes on it; and a rear tube, connected to said barrel, with an opening and silencer plug at appropriate place. When the engine of the car exhausting waste gas generated due to combustion, the flame companied with the waste gas could be resisted by the back-pressure device to avoid engine knock, the back-pressure device also could control and balance the flow rate when exhausting waste gas, so that it makes the engine working at low speed with high torque and speed, by this way, not only makes exhaust smoothly and reduces the burden when engine at high temperature, but also achieves the purpose of fuel saving.

摘要： A multi-cylinder internal combustion engine capable of decreasing the pressure or temperature of exhaust gas. The internal combustion engine includes at least two cylinders and an exhaust path. The exhaust path includes a convergent-divergent nozzle and an exhaust merging section provided upstream with respect to an upstream end of the divergent section arranged to connect only exhaust ports of combustion chambers for which the opening periods do not overlap. A shock wave propagating in a merging upstream section is branched at a connection section, and the branched shock wave is reflected by an exhaust valve of cylinder and collides against the exhaust gas. In accompaniment with the passage of the exhaust gas having the pressure increased by the shock wave through the convergent-divergent nozzle, a new shock wave propagating in a downstream direction in the exhaust path is generated and also an expansion wave propagating in an upstream direction in the exhaust path is generated. Thus, the temperature and pressure of the exhaust gas are significantly decreased.

摘要： An outboard motor includes an engine and an exhaust pipe. The engine has a crank case, a cylinder body, and a cylinder head aligned along the front-rear direction of the outboard motor, and arranged to support a crankshaft so as to extend along an up-down direction. The exhaust pipe is arranged to lead an exhaust gas of the engine to a main exhaust passage positioned below the engine. The cylinder head has an exhaust gas outlet opened in the side portion on one side of the cylinder head in the left-right direction of the outboard motor. The exhaust pipe has a bypass exhaust pipe which, in a plan view, extends from the exhaust gas outlet, bypasses the engine along the crank case, and reaches the other side in the left-right direction of the engine.
