Abstract

The present invention discloses an apparatus for reducing a pumping loss and an engine including the same. The apparatus for reducing the pumping loss may include an auxiliary runner formed in an air-intake unit supplying air to a cylinder, wherein intake air may be temporarily stored in the auxiliary runner by using a flow of an exhaust gas during an exhaust stroke, and the intake air stored in the auxiliary runner may be supplied to the cylinder together with the air introduced to the air-intake unit during an intake stroke.

Description

[0001] Cross References to Related Applications [0002] This application claims priority from Korean Patent Application No. 10-2012-0104197 filed on Sep. 19, 2012, the entire contents of which are hereby incorporated by reference for all purposes. technical field [0003] The present invention relates to a device for reducing pumping losses and an engine comprising the same, more particularly, the present application relates to a device for reducing pumping losses generated between intake strokes, and an engine comprising the same engine of the device. Background technique [0004] Internal combustion engines, especially four-stroke engines, obtain their driving force through the intake, compression, expansion or work, and exhaust strokes in each cylinder. [0005] However, during the closing of the intake valve between intake strokes, an idle interval is created in each cylinder, resulting in pumping losses and reduced performance. [0006] In particular, this phenomenon...
