摘要：Problem to be solved: to achieve the sufficient recirculation of exhaust gas incold mode after cold start and the compatibility of combustion stability are realizedwhile avoiding the large increase in equipment cost. Solution: the master piston 12 isoperated in the vicinity of the compression top dead center, and the master piston 12 isoperated to generate oil pressure in the oil passage 13, and the hydraulic piston 4 isdriven by this hydraulic pressure to open the exhaust valve 4 of the cylinder 1 to openthe compression pressure to obtain the braking force As for the compression pressureopen type engine brake, the oil passage 13 of the cylinder 1 which is an intake strokewhen the one is near the compression top dead center is connected by the
communication passage 26, and the operation of the master pistonA path switchingmeans (oil passage shut-off valve 27, communication passage shut-off valve 28) forswitching the path of the working oil 18 to open the exhaust valve 4 by operating the oilpassage 13 of another cylinder 1 in the intake stroke through the communicationpassage 26 is provided.
