Embodiment Construction

[0060] The following description relates to embodiments of a system and / or an exhaust gas recirculation (EGR) system for managing condensate that may accumulate in an engine intake. Specifically, the EGR system may include an EGR cooler that accumulates acid condensation caused by the presence of sulfur in fuel combusted in the engine, and the condensation management system includes a mechanism for preventing the acid condensation from corroding the EGR cooler and / or the engine. Such mechanisms may include storage tanks located on or remote from the EGR cooler to collect condensate, heaters that raise the temperature of the EGR cooler to prevent condensation from forming, and / or provide Corrosion resistant material.

[0061] engine systems such as figure 1 The engine system shown in may include a condensation management system. The condensate management system may include draining condensate from the one or more intercoolers, from the mixing zone / zones, and from the EGR cool...

Abstract

The invention discloses a method and systems for managing a condensate. Various methods and systems are provided for managing condensation. In one example, a system comprises an engine; an intercooler positioned in an intake passage downstream of a first turbocharger compressor; an exhaust gas recirculation (EGR) system including an EGR cooler defining at least a portion of an EGR passage and communicating with a mixing region where exhaust gas mixes with the compressed intake air; a condensate collector fluidly coupled to the EGR cooler to collect condensate from the EGR cooler, the condensate collector positioned within the EGR cooler; and a drain line coupled to the condensate collector, the drain line having an outlet fluidically coupled to a turbocharger turbine outlet.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to U.S. Provisional Application No. 62 / 147,072, filed April 14, 2015, entitled "METHOD AND SYSTEMS FOR MANAGING CONDENSATE," which is hereby incorporated by reference in its entirety for all purposes. technical field [0003] Embodiments of the subject matter disclosed herein relate to engine systems. Background technique [0004] To meet emission standards issued by various emission control agencies, internal combustion engines can be configured with various aftertreatment devices, such as selective catalytic reduction systems, and / or with exhaust gas recirculation (EGR) to reduce emission generation and removal from exhaust Emissions. Furthermore, despite widespread recognition of the environmental risks of sulfur in fuels, regulations limiting the amount of sulfur in fuels are not enforced globally. When fuel containing sulfur is burned in the combustion chamber of an engine, it fo...
