Abstract
A heat storage cover is provided in an engine room. The heat storage cover covers an engine from above and surrounds the periphery of an upper portion of the engine to internally store, through the medium of air, heat dissipated from the engine and block upward heat dissipation. The engine includes an air inlet for introducing, into a combustion chamber, high temperature air obtained by the heat storage cover blocking the upward heat dissipation.
Claims11
An air intake device for an engine, the intake device comprising:
- an intake passage for introducing air in an engine room into a combustion chamber of the engine;
- and
- a heat storage cover provided in the engine room, which covers the engine from above and at least partially surrounds a periphery of the engine to internally store, through a medium of air, heat dissipated from the engine and at least partially block upward heat dissipation, wherein
- the intake passage comprises an intake duct that is disposed on the outside of the heat storage cover,
- the intake duct includes an outside air introduction duct portion for introducing outside air which is outside the engine room and an inside air introduction duct portion for introducing air which is inside the heat storage cover inside the engine room,
- the inside air introduction duct portion comprises an air inlet for introducing, into the combustion chamber, high temperature air obtained by the heat storage cover blocking the upward heat dissipation, and
- the air inlet of the inside air introduction duct portion faces an inside of the heat storage cover.

- the air inlet of the intake passage faces an inside of the heat storage cover,
- the engine room comprises a radiator that dissipates heat of cooling water of the engine toward the engine, and
- the air inlet of the intake passage is disposed between the engine and the radiator,
- the air intake device further comprising a shutter that, when the high temperature air obtained by the heat storage cover is introduced into the combustion chamber, blocks ventilation to the radiator.
