サイクルエンジンのトルク増幅排気システム。A high-output main chamber and sub-chamber provided in the exhaust passage, a valve that opens and closes the communication between the sub-chamber and the exhaust passage, and a guide shaft that rotates in synchronization with the crankshaft are slidably attached to the inside of the engine. - During low-speed rotation, the valve is biased in the direction of opening by the biasing force of the biasing member, and during high-speed rotation, the valve slides in the direction of closing against the biasing force due to the action of the centrifugal governor, and the outer surface a slide body provided with a rack; a spindle having a pinion that meshes with the rack of the slide body and rotates as the slide body slides; and a spindle configured to open and close the valve by rotation of the spindle. and a transmission mechanism that transmits the rotational force of the rotation force to the valve, and maintains the valve in the closed position during medium and low speed rotation and operates both the main chamber and the sub-chamber, thereby adjusting the rotation force suitable for the rotation. The exhaust pulsation is synthesized and the high-speed rotation valve is closed via the slide body, spindle, and transmission mechanism to operate only the main chamber, creating the optimal exhaust pulsation for generating peak power. In the torque amplification exhaust system for a two-stroke engine, the anti-slide body is configured to prevent rotational force of the spindle from being transmitted to the rack by interposing a bearing between the rack and the spindle.
