A system and method for removing condensate water of an intercooler for a hybrid vehicle are configured to improve combustion efficiency of an engine by supercharging intake air to a combustion chamber of the engine using an electronic compressor instead of an existing turbocharger and configured to backward drive the electronic compressor to distribute and capture the condensate water generated in the intercooler, especially, when the engine is turned off.

System and method for removing condensate water of an intercooler for a hybrid vehicle

The present disclosure provides a boosting control method of an engine for cylinder de-activation (CDA). The method includes: a CDA operable area confirming step of determining, by a controller based on a driving state of the engine, whether the CDA is in an operable area after the engine starts; an actual boosting deriving step of deriving a total target boosting from the controller and calculating the desired actual boosting; a supercharger operable area confirming step of determining, by the controller, whether the supercharger is in the operable area; a supercharger target rotation speed deriving step of deriving, by the controller, a target rotation speed of the supercharger; and a supercharger passage opening step of closing a bypass valve to open a supercharger passage.

Boosting control method of engine for CDA

A control method of a boosting apparatus includes: driving the boosting apparatus according to driving maps pre-input to a controller, judging driving conditions of an engine, selecting a driving map pre-input to the controller and reflecting the driving conditions in the selected driving map, correcting the driving maps of the boosting apparatus based on the selected driving map and driving the boosting apparatus based on the corrected driving maps, and confirming whether variations in operating amounts of the boosting apparatus are generated and, when the variations are confirmed, correcting the operating amounts of the boosting apparatus and reflecting the corrected operating amounts in the driving maps. In particular, the controller controls an EGR valve according to driving conditions through operation of the boosting apparatus and thus controls the amount of EGR gas supplied to the engine.

Control method of boosting apparatus

The present disclosure relates to an exhaust purification apparatus and a method of controlling the apparatus. The exhaust purification apparatus includes: an injector for injecting urea solution into an exhaust pipe; a driving unit to provide driving force for adjusting an injection angle of the injector; and a control unit to determine the injection angle of the injector based on values of a spatial velocity, flow rate, pressure and temperature of exhaust gas and to drive the driving unit so as to control the injection angle of the injector. In particular, the injection angle of the injector is adjusted by pivotal movement of the injector.
