Air intake system for an engine

摘要

An air intake system is disclosed. The air intake system may have an air box. The air box may be configured to receive air from an ambient. The air intake system may also have a filter assembly disposed within the air box. The filter assembly may be configured to clean the air. In addition, the air intake system may have a duct. The duct may have a first duct end configured to receive the air exiting the filter assembly. The duct may also have a second duct end configured to deliver the air to the engine. The second duct end may be located at a gravitationally higher position than the first duct end.

1. An air intake system for an engine, comprising,
an air box configured to receive air from an ambient, and including an air box front wall with an air box front outlet port, an air box first side wall with a first air box inlet port, an air box second side wall with a second air box inlet port, an air box rear wall, and a longitudinal axis through the air box from the air box rear wall to the air box front wall; a filter assembly disposed within the air box and configured to clean the air, including a first filter bank removably disposed at the first air box inlet port, and a second filter bank removeably disposed at the second air box inlet port; and an elongated duct including:
a duct bottom portion,a duct top portion,a duct front wall with a duct front outlet port at the duct top portion and a front wall curved portion adjacent the duct front outlet port,a duct rear wall with a duct rear inlet port at the duct bottom portion fluidly connected to the air box front outlet port,a duct bottom wall having a bottom wall curved portion adjacent the duct front wall, anda duct top wall having a top wall curved portion adjacent the duct rear wall; and a converging nozzle portion including a rear nozzle inlet port fluidly connected to the duct front outlet port, a first front nozzle outlet port, and a second front nozzle outlet port; and wherein the air intake system defines an air path through the first air box inlet port and the second air box inlet port, through the filter assembly, through the air box in the direction of the longitudinal axis, through the air box front outlet port and the duct rear inlet port, through the duct from the duct bottom portion to the duct top portion, through the duct front outlet port and the rear nozzle inlet port, through the converging nozzle portion, through the first front nozzle outlet port and the second front nozzle outlet port and to the engine.
