    摘要: This invention is an exhaust gas recirculation apparatus such that exhaust gas recirculation master piston (12) is activated and acts to open exhaust valve (4) on the same cylinder (1) by driving a slave piston (14), thus recirculating exhaust gas into combustion chamber (2) from exhaust port (5) as a result of the pressure difference, thereby lowering the combustion temperature within combustion chamber (2) on the next power stroke and working to reduce NO x . Moreover, by selectively maintaining and releasing oil pressure in two types of passages (13) and (31), it can also be used as a compression pressure-release engine brake.
