摘要： A process of controlling operation in a multi-cylinder engine either during start of operation or low-load conditions is disclosed. The process may include skipping a supply of fuel in a first set of cylinders of the multi-cylinder engine for a pre-defined number of multiple working cycles. The process may further include supplying fuel-air mixture to a second set of cylinders of the multi-cylinder engine for the pre-defined number of multiple working cycles. The process may also include executing combustion of the fuel-air mixture supplied to the second set of cylinders for the pre-defined number of multiple working cycles. In addition the process may include either changing a selection of cylinders included in the first set of cylinders and the second set of cylinders respectively, or switching the supply of fuel, after the pre-defined number of multiple working cycles, from the second set of cylinders to the first set of cylinders.

摘要： A method of evaluating operability of a gaseous fuel admission valve of an internal combustion engine is disclosed. The method includes operating the internal combustion engine on gaseous fuel by repeatedly actuating the gaseous fuel admission valve. The method further includes measuring a sequence of temporal developments of an electrical operation parameter respectively associated with an actuation of the gaseous fuel admission valve. The sequence includes a first temporal development to be evaluated and a plurality of temporal developments preceding the first temporal development. The method also includes evaluating operability of the gaseous fuel admission valve based on the first temporal development of the measured sequence and at least one of the plurality of preceding temporal developments of the measured sequence.

摘要： A method for operating a spark ignited gaseous fuel internal combustion engine is disclosed. The engine may have at least one main combustion chamber and at least one ignition device configured to initiate an ignition event within an ignition region. The method may include supplying pressurized fuel to the ignition region at times between about 30° to about 0° crank angle before the ignition event is initiated by the ignition device for enriching the ignition region with fuel. The method may also include initiating an ignition event in the ignition region for combusting an enriched air/fuel mixture within the ignition region.

摘要： Directing exhaust gas around a catalyst may pre-heat the catalyst and may thereby bring the catalyst quickly in its operating temperature range. An exhaust gas treatment system for treating the exhaust gas may include a first flow path, a second flow path, and a control system. The first flow path may include a catalyst. The second flow path may be coaxially arranged in heat exchange relation with respect to the first flow path. The control system may be configured to control the flow of exhaust gas through the first flow path or the second flow path dependent upon the catalyst temperature.

摘要： A valve for a fuel supply of an internal combustion engine is disclosed. The valve may have a valve housing that defines a channel in fluid communication with an inert gas supply line at a first end of the valve housing. The valve housing may also have a first flange disposed at a second end distal to the first end. The valve may have a valve body that selectively allow the channel of the valve housing to communicate with an inner bore of a double-walled connecting element of the fuel supply system. The valve housing may also have a second flange disposed adjacent to the first flange. The first flange and the second flange define a detection gap therebetween. The second flange may have a passage in fluid communication with a detection space of the double-walled connecting element and the detection gap.

摘要： A control system is disclosed for operating an internal combustion engine. The control system includes a control unit configured for providing a part load mode that is optimized for slow operation of the engine at loads up to an upper part load limit in the range from 40% to 75% of a maximum engine load. The control unit is also configured for providing a high load mode for engine loads above the upper part load limit. In the part load mode, at least one inlet valve is closed at a closing angle later than in the high load mode.

摘要： A method to deliver natural gas (NG) to an internal combustion engine (ICE) via an fuel gas intake assembly is disclosed. The fuel gas intake assembly includes a gas intake manifold and at least one gas admission valve (GAV). The ICE is in fluid communication with the GAV. The method includes the provision of at least one lubrication introduction device, at least a portion of which is laden with a lubricant. The at least one lubrication introduction device is positioned downstream from the gas intake manifold and upstream from the GAV. A substantially pressurized NG is introduced into the gas intake manifold, which causes passage of the NG through the lubrication introduction device. This causes the NG to entrain lubricant from the lubrication introduction device, introduce the lubricant into the fuel gas intake assembly, and deposit the lubricant, at least partially, into the GAV.
