Abstract
A fouling free clean EGR system for a diesel-gasoline dual fuel powered engine allows re-circulation of an exhaust gas of a certain cylinder among a plurality of cylinders. The fouling free clean exhaust gas recirculation (EGR) system for a diesel-gasoline dual fuel powered engine in which gasoline and air are pre-mixed and supplied to cylinders and then a diesel fuel is injected and combusted together comprises a directly-exhaust cylinder of which an exhaust valve of the cylinder is connected to an exhaust manifold directly connected to a after treatment device; and an EGR cylinder of which an exhaust valve of the cylinder is connected to an EGR line and which supplies the EGR gas to the diesel-gasoline dual fuel powered engine.
