Abstract: PURPOSE: A diesel-gasoline complex fuel engine is provided to make a combustion chamber stratified into a high concentration EGR(Exhaust Gas Recirculation) space and a relatively low concentration EGR, thereby securing the ingnitionability in low-speed low-load area improves to improve combustion. CONSTITUTION: A diesel-gasoline complex fuel engine includes an EGR air intake port(10), an air intake valve(20), a gasoline injector and a diesel injector. The EGR air intake port comprises a tangential port(11) supplying the fuel-air mixture with low EGR rate and a helical port(12) supplying the fuel-air with high EGR rate. The air intake valve comprises a tangential valve(21) equipped on the tangential port and a helical valve(22) equipped on the helical port. The gasoline injector is equipped on an air intake manifold(30) and injects gasoline fuel into the air. The diesel injector injects diesel fuel directly into combustion chamber(3) instead of a spark plug. [Reference numerals] (AA) Exhaust gas;
