EXHAUST VALVE ACTUATION SYSTEM FOR DIESEL PARTICULATE FILTER REGENERATION |
摘要 |
An exhaust valve actuation system (30) for initiating a regeneration event at a diesel particulate filter (24) includes an engine control module (42) associated with an engine (14). A plurality of exhaust valves (32) correspond to a plurality of engine cylinders (C1-C6). When either a predetermined amount of back pressure or a predetermined temperature, or both, are communicated to the engine control module (42), the engine control module actuates at least one exhaust valve (32) to open. Gas or gas-fuel mixture is compressed and heated inside of the cylinder (C1) corresponding to the opened exhaust valve (32). At least one exhaust valve (32) is not opened by the engine control module (42), which permits combustion inside the corresponding cylinder (C2).
