INTERNAL COMBUSTION ENGINE Russian patent published in 2001 - IPC

Abstract RU 2173400 C2

FIELD: mechanical engineering; internal combustion engines. SUBSTANCE: invention relates to engines operating with partial bypassing of exhaust gases into intake system. Proposed internal combustion furnished with exhaust gas recirculation system has intake pipe 2 in assembly with receiver 3 secured on cylinder head 1 and channel 4 to let out exhaust gases made in cylinder head 1. Space of channel 4 communicates through gas duct with receiver space 7. Recirculation valve 5 with shutoff element is installed in gas duct. Intake pipe 2 in its joint 8 with cylinder head 1, and receiver 3 are provided with flanges 9 and 10, respectively. Flanges are rigidly and hermetically connected to each other. Gas duct is formed by mated channels 11 in cylinder head 1 and channel 12 in flange 9 of intake pipe 2, channels 13 and 14 in flange 10 of receiver 3. Recirculation valve 5 is mounted on flange 10 of receiver 3 in geodesically upper point of gas duct. EFFECT: provision of simple and compart design of exhaust gas recirculation system, optimum arrangement of recirculation system elements in internal combustion engine. 2 cl, 2 dwg
