Abstract
An amphibian motor vehicle comprises a watertight engine room formed in a lower part of a vehicle body, an air intake opening formed at a front part of the vehicle body such that the air intake opening is positioned above water level when the amphibian motor vehicle cruises on water, an air passage separated from the engine room and generally extending in a longitudinal direction of the vehicle body from the air intake opening and a radiator disposed in the air passage for air cooling a coolant flowing into the radiator from the engine.
Claims15
An Amphibian motor vehicle of the type having a radiator for air cooling a coolant flowing in the radiator from an engine but not having a fan for cooling the radiator, comprising:
- a watertight engine room formed in a lower part of a vehicle body and housing the engine;
- an air intake opening formed at a front part of the vehicle body such that the air intake opening is positioned above water level when the amphibian motor vehicle cruises on water;
- an air passage disposed above the engine room and extending to an air exit formed at an upper front part of the vehicle body, the air passage being separated from the engine room by a plate member and extending from the air intake opening generally horizontally or slightly downward in the longitudinal direction of the vehicle body such that an ambient air naturally flows into the air intake opening as the amphibian motor vehicle moves forward and a sufficient amount of air is guided by the air passage and directly introduced to the radiator to cool the radiator, the radiator being disposed in the air passage;
- and
- means for supporting the radiator means in a position inclined forward relatively close to horizontal.
An amphibian motor vehicle of the type having a radiator for air cooling a coolant flowing in the radiator from an engine but not having a fan for cooling the radiator, comprising:
- a watertight engine room formed in a lower part of a vehicle body and housing the engine;
- an air intake opening formed at a front part of the vehicle body such that the air intake opening is positioned above water level when the amphibian motor vehicle cruises on water;
- an air exit formed at a lateral part of the vehicle body, the air exit opening to the atmosphere at a position above and behind front wheels of the vehicle;
- and
- an air passage separated from the engine room by a plate member and extending generally horizontally or slightly downward in the longitudinal direction of the vehicle body from the air intake opening to the air exit, the radiator being located in the air passage such that an ambient air flows into the intake opening as the amphibian motor vehicle moves forward and a sufficient amount of air is guided by the air passage and directly introduced to the radiator to cool the radiator.
