AIR COOLING SYSTEM OF AUTOMOTIVE ENGINE
First Claim
1. An engine cooling arrangement for a motor vehicle having a front engine compartment and an engine disposed in the engine compartment with its crankcase being transverse with respect to the longitudinal direction of the vehicle, comprising in combination:
- a radiator for the engine coolant disposed in the front plane of the engine compartment for directly receiving ambient fresh air, said radiator partially covering the front plane of the engine compartment for forming an aerodynamic air intake at the uncovered front plane to allow fresh air to directly flow into the engine compartment while the vehicle is running at high speed;
a duct disposed in the engine compartment downstream of said radiator for receiving heated air converted from the fresh air passing through said radiator and having an outlet substantially sideways of the engine compartment, said duct having a vent formed in a position opposite and behind with respect to said outlet thereof, said vent opening into the engine compartment; and
a fan having a rotary shaft arranged substantially in parallel with the crankcase of the engine and having a propeller disposed adjacent to said outlet of said duct so as to forcibly convey said heated air in said duct to the outside of the vehicle through said outlet and so as to forcibly remove stagnant hot air from the engine compartment through said vent and said outlet of said duct to the outside of the vehicle when the vehicle is running at low speed.

Abstract
A cooling arrangement for an automotive internal combustion engine having a crankshaft oriented rectangular to the longitudinal direction of the motor vehicle, which system includes a radiator positioned in front of the engine compartment and vented from the open air, a duct communicating at one end with the radiator and opened at the other to the open air in a direction rectangular to the longitudinal direction of the vehicle, and a fan provided in the duct and driven by the crankshaft of the engine. The radiator may cover an either total or partial front area of the engine compartment and the duct may have a branch duct communicating with the occupants'"'"''"'"' room.
