ことを特徴とする排気ブレーキ。[Scope of utility model registration claim] Interposed in the middle of the exhaust pipe of an automobile engine,
A butterfly valve that opens and closes the exhaust passage, an actuator that drives the butterfly valve to three opening positions: fully open, small opening, and slight opening; and a selected opening for the actuator. and a controller to which a detection signal of the engine rotational speed is input, and the input rotational speed is in the low speed range (or medium speed range or high speed range). An exhaust brake characterized in that a controller is formed to control the operation of the activation means to a fully open position (or a slightly opened position, a small opening position).
