An apparatus for controlling a gasoline-diesel complex combustion engine includes an engine generating driving torque by burning gasoline fuel and diesel fuel, a driving information detector for detecting driving information of the engine, and a controller for controlling a diesel injector such that diesel fuel is injected as a single injection or a split injection based on a driving region and a knock intensity included within the driving information.

Apparatus for controlling gasoline-diesel complex combustion engine and method for controlling gasoline-diesel complex combustion engine

A method of controlling combustion of an engine improves unstable ignition and knocking which may be generated in an engine to which a diesel-gasoline mixed combustion mode and a gasoline mixed combustion mode are applied to low load and high load driving zones. The method includes: determining a combustion mode according to a current driving state of the engine; determining a compression ratio corresponding to the combustion mode; controlling a variable compression ratio device to control a compression ratio of a cylinder; determining whether the combustion state of the engine obtained during the combustion after the control to the compression ratio satisfies a set condition; and performing a compression ratio compensation such that the combustion state of the engine satisfies the set condition with taking a combustion pressure sensor signal as a feedback signal when the set condition is not satisfied.
