ABSTRACT:
A negative pressure air stream accelerator for a suction type air cooling mechanism for cooling an internal combustion engine produces negative pressure by accelerating the exhaust gas stream to form a strong negative pressure connected to the cooling device to draw cooling air therethrough, and accelerates the velocity of the exhaust gas by providing at least one stage of acceleration units for throttling by a reduced cross-sectional area of the exhaust gas passage having an outer casing connected to the cooling device, the accelerator having holes through the walls thereof communicating with the interior of the casing. A plurality of stages are provided in series for utilizing the air stream accelerated to a high velocity at the final negative pressure stream.
