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.

摘要: The present invention is directed to an exhaust gas recirculation apparatus in which an exhaust-gas-recirculation master piston (12) is actuated by a suction rocker arm (10) to drive a slave piston (14) which in turn opens an exhaust valve (4) on the same cylinder (1) during a suction stroke. As a result, owing to pressure difference, the exhaust gas is recirculated from an exhaust port (5) into a combustion chamber (2) to lower the combustion temperature in the combustion chamber (2) during a next power stroke and to promote decrease of NO x .
