Abstract

An engine air intake system is provided which is formed by an engine compartment. A fan and a grille screen are used to remove a portion of debris from air external to the vehicle. After the air is partially cleaned via the grille screen, it moves toward a heat exchanger carrying a portion of the remaining debris with it. A portion of the debris may fall out of the air via gravitational effects. A portion of the air then moves up and into an entrance passage for an air intake duct that is integrated with the hood of the engine enclosure, this portion having been further cleaned via debris passage to and through the heat exchanger as well as gravitational effects. The air then travels through the air intake duct and passes through an air filter where a portion of the remaining debris is removed prior to the air being supplied to the engine intake.

Dependent claims

An air intake system for a vehicle comprising:

an engine enclosure, the engine enclosure comprising a hood and at least one side wall;
an engine;
a heat exchanger;
a screen;
a filter;
a filter supply duct;
and
a fan, the hood including an air intake duct along a length of the hood, the air channel integral to the hood and supplying intake air for the engine, the air intake duct having an entrance passage providing for air flow in a direction substantially orthogonal to a direction of the air intake duct, the entrance passage longitudinally located between the screen and the heat exchanger, the fan moving a first ambient air through the screen and a second ambient air into the engine enclosure, the fan moving the second ambient air through the heat exchanger, the engine moving a third ambient air through the entrance passage and into the air intake duct via an air intake duct pressure lower than a pressure of the second ambient air, the engine moving the third ambient air through the filter via a pressure in the filter supply duct to provide a fourth ambient air.
