Abstract: The present disclosure provides a technology of determining an engine friction torque even when idling of an engine is not performed, by providing a certain engine Revolutions per Minute (RPM) in stop state of the engine using Hybrid Starter & Generator (HSG) connected to an engine pulley. The present disclosure provides a technology of determining an accurate engine friction torque using a torque provided from the outside of an engine instead of a torque generated the engine itself.

Abstract: A system for treating blow-by gas in a PCV (positive crankcase ventilation) system of an internal combustion engine is provided, which comprises a cut-off valve assembly for selectively opening or closing an air duct, a blow-by gas collecting assembly for collecting blow-by gas inside an air intake passageway and ejecting the collected blow-by gas into an intake manifold such that the blow-by gas is re-burned in a combustion chamber, and a controller for controlling operations of the cut-off valve assembly and the blow-by gas collecting assembly.

Abstract: An apparatus for treating the exhaust gas of internal combustion engine comprises an injector, a valve for shutting off the cooling water which flows into a cylinder head, an exhaust manifold increasing the fluidity of the exhaust gas, a close-coupled catalyst (CCC) increasing the activation of a catalyst with high loading operation in case of low temperate, an HC-absorber catalyst including an HC absorber and a TWC catalyst component for removing the HC component in the exhaust gas, and a electrically heated catalyst and a light off catalyst for removing the HC component at high temperate.
