Document Type and Number:
WIPO Patent Application WO/2023/084747
Kind Code:
A1
Abstract:
An internal combustion engine (10) comprises a combustion chamber (28), a spark plug (43), an intake port (30), and an exhaust port (31). A tip (43a) of the spark plug (43) is positioned between the intake port (30) and the exhaust port (31) and to the side thereof. Where the side of the combustion chamber (28) where the tip (43a) of the spark plug (43) is disposed, in a plan view of the combustion chamber (28), is an R-side space (SR), and the side opposite to the R-side space (SR) is an L-side space (SL), an air current (F) traveling from the R-side space (SR) to the L-side space (SR) is generated in the combustion chamber (28), and a fuel-air mixture is supplied to the combustion chamber (28) such that the concentration of ethanol-containing fuel in the fuel-air mixture included in the L-side space (SL) is higher than the concentration of the ethanol-containing fuel in the fuel-air mixture included in the R-side space (SR).
