Title:
INTERNAL COMBUSTION ENGINE
Document Type and Number:
WIPO Patent Application WO/2005/047668
Kind Code:
A1
Abstract:
An internal combustion engine capable of generating a tumble flow and adjusting the formation of a tumble flow by using a simple arrangement. An internal combustion engine (100) has a suction pipe (22) for introducing air into a combustion chamber (10) wherein in the suction pipe (22), a throttle valve (30) for adjusting the amount of inflow of air (50) introduced into the combustion chamber (10) is disposed. The throttle valve (30) has a first end (30a) and a second end (30b). At upstream (51) of the throttle valve (30), the inner surface of the suction pipe (22) is provided with a level difference (40) for strengthening the air flow (50b) toward the second end (30b) more than the air flow (50a) toward the first end (30a) of the throttle valve (30).
