Air intake configuration for an agricultural harvesting machine
First Claim
1. An agricultural work vehicle, comprising:
- a vehicle body;
an enclosed engine compartment within said vehicle body, said engine compartment having a top cover that extends between opposite sides of said vehicle body;
a vertically oriented air inlet in said vehicle body for intake of air into said engine compartment;
an intake housing configured over said air inlet, said intake housing having an inlet opening and an outlet opening in communication with said air inlet;
said inlet opening extending above said top cover and oriented relative to a vertical plane such that an angled air flow path is defined between said inlet opening and said outlet opening wherein air is drawn from an area above said top cover and directed into said air inlet; and
wherein said intake housing is mounted over said air inlet and has a bend between said inlet opening and said outlet opening such that the air is drawn substantially in a direction across said top cover from an opposite side of said top cover from an area above a portion of the vehicle body into said inlet opening.

Abstract
An agricultural work vehicle includes an enclosed engine compartment within the vehicle body, with the engine compartment having a top cover that extends generally between opposite sides of the vehicle body. A vertically oriented air inlet is defined in the vehicle body for intake of air into the engine compartment. An intake housing is configured over the air inlet and includes an inlet opening and an outlet opening in communication with the engine compartment air inlet. The inlet opening extends above the top cover and is oriented relative to a vertical plane such that an angled air flow path is defined between the inlet opening and the outlet opening wherein air is drawn from an area above the top cover of the engine compartment and is directed into the air inlet.

15. A method for supplying engine combustion and cooling air to an internal combustion engine of a work vehicle, wherein the engine is housed in an engine compartment having a top cover that extends between sides of a vehicle body, and wherein an air inlet is provided in the vehicle body for intake of air into the engine compartment, the method comprising:
-
configuring an intake housing over the air inlet and drawing air into the intake housing from an area above the top cover; and drawing air into the intake housing from above a portion of the vehicle wherein said intake housing is mounted to said vehicle body over said air inlet and has a bend between said inlet opening and said outlet opening such that the air is drawn substantially in a direction across said top cover from an opposite side of said top cover. - View Dependent Claims (16)
