Abstract

In systems in which there is insufficient pressure difference between the intake and the exhaust to drive the EGR, an EGR pump is provided. In a dual-engine system, disclosed herein, the EGR system, i.e., the EGR cooler and EGR pump, is shared to obviate the need for two of each. Shutoff valves may be provided between the EGR system and a secondary of the two engines to isolate the secondary engine when it is not operating. When the engines are OPOC engines, exhaust aftertreatment devices, such as diesel oxidation catalysts and / or diesel particulate filters, may be placed upstream of where the EGR gases tee off from the engine's exhaust to thereby maintain a high pressure ratio across an exhaust turbine located downstream in the engine's exhaust.

Description

technical field [0001] The present invention relates to an EGR and aftertreatment system for an engine system having multiple engines, and also to a method of controlling the system. Background technique [0002] An engine system with two internal combustion engines has the potential to provide higher fuel burn efficiency. When the torque demand is small, only one of the two engines is run. However, operation of both engines may be permitted to meet high torque demands. One challenge was to avoid completely duplicating all engine accessories. Contents of the invention [0003] An internal combustion engine system is disclosed that includes a first internal combustion engine and a second internal combustion engine. The system also includes: a first exhaust aftertreatment device disposed in the engine exhaust port downstream of the first engine, a second exhaust aftertreatment device disposed in the engine exhaust port downstream of the second engine, disposed in the firs...
