PURPOSE: A ventilator for a vehicle is provided to simplify the structure of a combustion chamber and to reduce manufacturing costs by controlling the on/off of each path only through the rotation of control shafts for a suction port and an exhaust port. CONSTITUTION: A ventilator is composed of a suction port and an exhaust port. The suction port has a control shaft for controlling the suction of each cylinder by forming a suction hole for a mixer interlocked with a pulley for a crankshaft and to control the suction of two combustion chambers. The exhaust port includes a control shaft for controlling the exhaust of each cylinder by forming an exhaust hole for combustion gas interlocked with the pulley of the crankshaft and to control the exhaust of the two combustion chambers. |
