Front end structure for vehicle

A front end structure for a vehicle, comprising:

• a fascia member defining a forward end of an engine compartment of the vehicle;
• a radiator disposed in the engine compartment rearwardly spaced from the fascia member;
• a duct member interposed between the fascia member and the radiator, the duct member at least partially blocking airflow to the radiator and defining a duct passage extending from an underside opening of the vehicle to the radiator,
• a grill opening defined in the fascia member to admit and direct airflow to a front side of the radiator and over the duct member, the duct member at least partially blocking the airflow from the grill opening from passing to the radiator;
• at least one duct opening defined in the duct member to supplement airflow to the radiator from the underside opening;
• at least one auxiliary opening defined in the fascia member and fluidly connected to the at least one duct opening defined in the duct member,
• wherein the at least one auxiliary opening includes first and second auxiliary openings that are laterally spaced apart below the grill opening and the at least one duct opening includes first and second duct openings, the first auxiliary opening fluidly connected to the first duct opening and the second auxiliary opening fluidly connected to the second duct opening.

A front end structure for a vehicle, comprising:

• a fascia member defining a forward end of an engine compartment of the vehicle;
• a radiator disposed in the engine compartment rearwardly spaced from the fascia member;
• a duct member interposed between the fascia member and the radiator, the duct member at least partially blocking the radiator and defining a duct passage extending from an underside opening of the vehicle to the radiator;
• at least one duct opening defined in the duct member for supplementing airflow to the radiator from the underside opening;
• and
• at least one auxiliary opening defined in the fascia and fluidly connected by a sealed passageway to the at least one duct opening defined in the duct, the sealed passageway defined by an auxiliary duct member extending between the at least one auxiliary opening and the at least one duct opening.

A vehicle front end, comprising:

• a fascia member defining a forward end of an engine compartment of a vehicle;
• a radiator disposed in the engine compartment rearwardly of the fascia member;
• an underside air inlet opening defined in an underside of the vehicle;
• a duct member extending upward from a leading edge of the underside air inlet opening and directing airflow entering the underside air inlet opening toward the radiator;
• a duct opening defined in the duct member that allows a supplemental airflow to pass through the duct member to the radiator;
• and
• an auxiliary duct member extending between an auxiliary opening defined in the fascia member and the duct opening defined in the duct member, the auxiliary duct member defining a sealed duct passageway between the auxiliary opening defined in the fascia member and the duct opening defined in the duct member.

A method for supplying airflow to a radiator inside an engine compartment of a vehicle, comprising:

• directing airflow from an underside air inlet opening of the vehicle along an underside airflow path to the radiator with a duct member, the duct member at least partially blocking airflow to the radiator;
• directing supplemental airflow along a supplemental airflow path extending from an auxiliary opening defined in a fascia member through a duct opening defined in the duct member to the radiator to supplement airflow from the underside air inlet opening, wherein the underside airflow path converges with the supplemental airflow path;
• and
• directing airflow from a grill opening defined in the fascia member above the auxiliary opening to a front side of the radiator by passing over the duct member.
