摘要： A method is disclosed for controlling operation of an engine coupled to an exhaust treatment catalyst. Under predetermined conditions, such as after an engine cold start, the method operates an engine with a first group of cylinders having a first ignition timing, and a second group of cylinders having a second ignition timing more retarded than the first group. In addition, the engine control method also provides the following features in combination with the above-described split air/lean mode: idle speed control, sensor diagnostics, air/fuel ratio control, adaptive learning, fuel vapor purging, catalyst temperature estimation, default operation, and exhaust gas and emission control device temperature control. In addition, the engine control method also can change to combusting all cylinders at substantially the same ignition timing under preselected operating conditions such as fuel vapor purging, manifold vacuum control, and purging of stored oxidants in an emission control device.

摘要： An exhaust treatment device is provided for an internal combustion engine of a marine propulsion system. An outer chamber contains a first inner chamber within it and slidably supports the inner chamber. An exhaust inlet conduit directs a stream of exhaust gases from a cylinder of the internal combustion engine directly into the inner chamber. The inner and outer chambers are supported relative to each other to allow relative movement of these two components in response to changes in the differential temperature between the two components. A rail system slidably supports the inner chamber relative to the outer chamber. The exhaust treatment device comprises a liquid cooled housing surrounding the inner and outer chambers. Exhaust gas is directed through the inner chamber and then into the outer chamber at a closed end of the exhaust treatment device. Exhaust gases then flow through the outer chamber to an exhaust conduit of the marine propulsion system.

摘要： In an exhaust control valve having a valve housing and a valve body rotatably contained in the valve housing, a transmission member is fitted to an outer end of the valve shaft and protrudes from the outside of the valve housing. A bearing bushing for rotatably bearing an external circumferential surface of the valve shaft by its internal circumferential surface and rotatably bearing an end face of the valve body by its end face is mounted in the valve housing. The valve body is urged by load from a thrust spring for achieving a pressure contact seal condition between the opposed end faces of the bearing bush and the valve body.

摘要： In a catalyst body using a direct support, this invention provides a ceramic catalyst body capable of adjusting catalyst performance in accordance with intended objects such as prevention of deactivation of a main catalyst component when an sub catalyst component is used, or improvement of initial purification performance. When both main catalyst component and sub catalyst component are supported on a ceramic support capable of directly supporting the catalyst components, the invention first supports a catalyst metal as a main catalyst such as Pt, for example, and then supports the sub catalyst such as CeO2 on the main catalyst. The main catalyst is thus prevented from being involved in the grain growth of the sub catalyst, and becomes a catalyst body that does not easily undergo thermal deactivation. The ceramic support uses cordierite, a part of the constituent elements of which are replaced, so that the replacing elements so introduced can directly support the catalyst components. The bonding strength of the catalyst components can thus be improved and the thermal durability of the catalyst can also be improved.
摘要翻译：在使用直接载体的催化剂体中，本发明提供一种能够根据预期目的调节催化剂性能的陶瓷催化剂体，例如在使用副催化剂组分时防止主催化剂组分失活或提高初始纯化性能。当主催化剂组分和次催化剂组分两者负载在能够直接负载催化剂组分的陶瓷载体上时，本发明首先例如支持催化剂金属作为主要催化剂例如Pt，然后支持次催化剂如CeO 2 在主催化剂上。因此，可以防止主催化剂参与副催化剂的晶粒生长，成为不容易发生热失活的催化剂体。陶瓷载体使用堇青石，其组分的一部分被替换，使得如此引入的替代元素可直接支撑催化剂组分。因此可以提高催化剂成分的结合强度，也可以提高催化剂的耐久性。

摘要： A piston internal combustion engine with at least one gas exhaust valve (2) for each cylinder (1), which is actuated by an actuator (7), in particular an electromagnetic actuator, controlled by a fully variable engine control unit (15). Based on the predetermined operating cycle, the valve can close off the cylinder interior space against a gas exhaust channel (13) that follows the valve seat (3) of the exhaust valve. This channel is connected to an exhaust gas system and is provided with a means for example a constriction (14) for reducing the pressure gradient during the start of the opening of the gas exhaust valve (2). A specific pressure fluctuation is used for a further reduction in the pressure gradient behind the exhaust valves during the opening through a corresponding layout of the pipe geometry and the container volumes in the exhaust gas system or corresponding installed components.
