상시 직결된 엔진과 모터를 포함하는 하이브리드 차량의 펌핑로스 저감 시스템 및 방법이 개시된다. 상기 하이브리드 차량의 펌핑로스 저감 시스템은, 상기 엔진의 흡기 측으로 공급되는 외부 공기량을 결정하는 스로틀 밸브; 상기 엔진의 배기 측에서 흡기 측으로 연소가스를 공급/차단하는 EGR 밸브; 및 상기 엔진이 퓨얼 컷 상태이고 상기 모터를 구동하는 운전 모드에서, 상기 스로틀 밸브 또는 상기 EGR 밸브를 개방하여 상기 엔진 내 부압을 저감시키는 컨트롤러를 포함한다.

    Disclosed are a system and method for reducing pumping loss of a hybrid vehicle that can reduce the pumping loss of an engine without adding hardware and include an engine and a motor directly connected. The system for reducing pumping loss of a hybrid vehicle comprises: a throttle valve for determining an amount of external air supplied to an intake side of the engine; an EGR valve for supplying/blocking combustion gas from an exhaust side of the engine to the intake side; and a controller configured to reduce the internal pressure of the engine by opening the throttle valve or the EGR valve in a driving mode in which the engine is in a fuel cut state and the motor is driven.
