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