Abstract
An intake system for an engine including a first air filter assembly in fluidic communication with an intake manifold and a second air filter assembly spaced away from the first air filter assembly and in fluidic communication with the intake manifold.
Claims21
An intake system for an engine comprising:
- a first air filter assembly in fluidic communication with an intake manifold;
- and
- a second air filter assembly spaced away from the first air filter assembly and in fluidic communication with the intake manifold in parallel with the first air filter assembly, an inlet face of the first air filter assembly facing downward, and an inlet face of the second air filter assembly facing approximately horizontal and perpendicular to the inlet face of the first air filter assembly, where the first air filter assembly and the second air filter assembly do not share a common filter mount.
A method for operation of an intake system for an engine comprising:
- flowing intake air through a first air filter assembly including porous foam positioned upstream of a filter element, the first air filter assembly spaced away from a second air filter assembly having a filter of a different material than the first air filter and in fluidic communication with an intake manifold;
- and
- flowing filtered intake air from the first air filter assembly to the intake manifold, wherein the first air filter assembly and the second air filter assembly do not share a common housing, do not share a common housing body, and do not share a common filter mount, where the first air filter assembly is positioned external to an engine compartment, and where the second air filter assembly is positioned within the engine compartment.
An intake system for an engine, comprising:
- a first air filter assembly in fluidic communication with an intake manifold;
- a second air filter assembly spaced away from the first air filter assembly and in fluidic communication with the intake manifold, an inlet face of the first air filter assembly facing downward, and an inlet face of the second air filter assembly facing approximately horizontal and perpendicular to the inlet face of the first air filter assembly;
- a connector duct in direct fluidic communication with the first air filter assembly;
- and
- a filtered air compartment included in the second air filter assembly downstream of a filter element in the second air filter assembly, where the first air filter assembly and the second air filter assembly do not share a common filter mount.
