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.
Claims23
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.
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 in fluidic communication with an intake manifold;
- and
- flowing filtered intake air from the first air filter assembly to the intake manifold.
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;
- and
- 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.
