Abstract
A vehicle system, includes an air intake assembly including an inlet through which air flows, a filter downstream of the inlet, and an outlet downstream of the filter through which air from the filter flows, a liquid source, a valve, a temperature indicator and a controller. The valve is electrically actuated and arranged to selectively permit liquid flow from the liquid source to the air intake assembly. The temperature indicator provides an indication of a temperature in the air intake assembly upstream of the filter. And the controller is communicated with the temperature indicator and the valve and operable to open the valve when the output of the temperature indicator indicates a temperature above a temperature threshold.
Claims20
A vehicle system, comprising:
- an air intake assembly including a housing having an interior and an inlet through which air flows into the interior, a filter is located downstream of the inlet, and an outlet is located downstream of the filter through which air from the filter flows;
- a liquid source;
- a passage arranged to receive liquid from the liquid source, the passage is in heat transfer relationship with the housing and the passage is outside of the interior;
- a valve that is electrically actuated and arranged to selectively permit liquid flow from the liquid source to the air intake assembly through the passage;
- a temperature indicator providing an indication of a temperature in the air intake assembly upstream of the filter;
- and
- a controller communicated with the temperature indicator and the valve and operable to open the valve when the output of the temperature indicator indicates a temperature above a temperature threshold.
A method of selectively decreasing the temperature within an air intake for an engine, comprising:
- determining a temperature indicative of a temperature in an air intake assembly;
- comparing the temperature to a temperature threshold;
- and
- providing, when the determined temperature does not satisfy the temperature threshold, flow of a liquid from a liquid source to an air intake assembly through which air is delivered to an engine to support combustion in the engine, wherein the liquid is maintained separate from the air flow through the air intake assembly and the liquid is routed outside of an interior of the air intake assembly.
