Abstract
Various methods and systems are provided for an air induction system for an engine. In one example, the air induction system includes an intake conduit and an assembly coupled to the intake conduit which includes a water spray for removing particulates from, and for cooling, intake air flowing through the water spray.
Claims23
An air induction system for an engine, comprising:
- an intake conduit;
- and
- an assembly coupled to the intake conduit including a water spray for removing particulates from, and for cooling, intake air flowing through the water spray, the water spray being delivered by at least one conduit, the at least one conduit including a plurality of upstream conduits fluidically coupled to an upstream header and a plurality of downstream conduits fluidically coupled to a downstream header, the upstream conduits delivering a higher pressure water spray than the downstream conduits.
An air induction system for an engine, comprising:
- an intake conduit;
- and
- an assembly coupled to the intake conduit including a water spray for removing particulates from, and for cooling, intake air flowing through the water spray, the assembly further including one or more curved slats traversing the assembly in a direction perpendicular to a flow direction of the intake air, the one or more curved slats changing the flow direction of, and generating turbulence in, the intake air flow, wherein at least one of the one or more curved slats is positioned upstream of a conduit that delivers the water spray to the assembly.
A method for an air intake system, comprising:
- inducting a flow of intake air through an assembly;
- generating turbulence in the flow of intake air in the assembly;
- removing particulates from the flow of intake air via a plurality of water sprays in the assembly including an upstream water spray from a plurality of upstream conduits and a downstream water spray from a plurality of downstream conduits by operating a high pressure water pump to deliver the upstream water spray to an interior of the assembly, the upstream water spray delivering a higher pressure water spray than the downstream water spray and spanning a cross-section from top to bottom of the interior of the assembly;
- cooling the flow of intake air via the plurality of water sprays in the assembly;
- and
- directing the flow of intake air from the assembly to an engine.

An article of manufacture, comprising:
- a water spray region through which particulate-laden intake air can flow;
- a plurality of turbulence-generating slats traversing the water spray region in a direction perpendicular to a flow direction of the intake air;
- a high pressure water assembly with one or more first water delivery conduits traversing the water spray region for removing particulate from the intake air;
- a low pressure water assembly with one or more second water delivery conduits traversing the water spray region for cooling the intake air;
- and
- a water circuit fluidically coupled to the high pressure water assembly and the low pressure water assembly including a high pressure pump for the high pressure water assembly and a low pressure pump for the low pressure water assembly.
3 more elements
An air induction system for an engine, comprising:
- an intake conduit having an ingress and an egress, the ingress for receiving intake air from external to the engine and the egress for delivering the intake air to an intake of the engine;
- and
- an assembly coupled to the intake conduit between the ingress and egress, the assembly including a water spray for removing particulates from, and for cooling, the intake air flowing through the water spray and one or more curved slats transversing the assembly in a direction perpendicular to a flow direction of the intake air, at least one of the one or more curved slats being positioned upstream of a conduit that delivers the water spray;
- wherein the assembly includes an unimpeded airflow path, at a macro level, the airflow path extending from the ingress to the egress, whereby the intake air flowing through the assembly encounters only the water spray for particulate filtration.
