エンジンブレーキ力増大装置。[Claims for Utility Model Registration] 1. In a braking device that exhausts the atmosphere from the combustion chamber of an internal combustion engine for braking, a passage connected to the combustion chamber and from which the atmosphere is exhausted to the outside, and an opening/closing device for opening and closing the passage. an atmosphere compressed by the on-off valve, comprising: a valve; and on-off valve operating means for opening and closing the on-off valve in synchronization with the internal combustion engine so as to open the on-off valve from the end of the compression stroke to the expansion stroke of the internal combustion engine; An engine braking force increasing device characterized in that the internal combustion engine is braked by discharging the internal combustion engine from the combustion chamber to the outside through the passage. 2. The engine braking force increasing device according to claim 1, wherein the on-off valve is biased to a closed state so as to open the passage only during braking. 3. The opening/closing valve is formed of a rotating body to rotate once during the intake, compression and expansion, and exhaust strokes of the internal combustion engine, and is configured to open the passage when the internal combustion engine moves from the end of the compression stroke to the expansion stroke. The engine braking force increasing device according to claim 1 or 2, characterized in that it has a notch.
