Abstract

A diesel-gasoline dual fuel powered combustion engine system is provided with spark-assisted fouling free EGR system in which gasoline and air are homogeneously combined and supplied to cylinders and then a diesel fuel is injected and combusted together. The system may include: a plurality of cylinders (11, 12, 13, 14) each having a fuel injector (11a, 12a, 13a, 14a) ; and an exhaust line (20) through which flows an exhaust gas discharged as a fuel from each cylinder is combusted; wherein gasoline fuel combustion type is adapted to one or more cylinder (14) of the plurality of the cylinders, and diesel-gasoline fuel pre-mixed combustion type is adapted to the other cylinders (11, 12, 13).

Description

[0001] Cross References to Related Applications [0002] This application claims priority from Korean Patent Application No. 10-2011-0136614 filed on December 16, 2011, the entire contents of which are hereby incorporated by reference for all purposes. technical field [0003] The present invention relates to a diesel-gasoline dual-fuel internal combustion engine system with a spark-assisted combustion non-fouling EGR system, in particular to an exhaust gas regeneration control system for a homogeneous charge compression ignition engine combining gasoline and diesel fuel and its A method that makes it possible to suppress the generation of deposits generated in an EGR system by controlling the ignition timing of an HCCI engine combining gasoline and diesel fuel. Background technique [0004] Exhaust gas recirculation (EGR) systems are widely installed in vehicles to reduce NOx by recirculating exhaust gas from an engine and introducing it into cylinder interiors. The EGR sy...
