Abstract

An ignition plug 26 is attached on a cylinder head 14 at a position shifted from a center of the combustion chamber 19 and corresponding to an air inlet port 20 of a parallel direction one end side of a plurality of the air inlet ports 20, 21 arranged in parallel, and a guide wall 142 guiding intake air flowing in the combustion chamber 19 from the inlet air port 20 on the one end side to bypass the ignition plug 26 is provided on a ceiling wall 19a of the combustion chamber 19 around an opening end of the inlet air port 20 of the one end side to the combustion chamber 19.

Description

technical field [0001] The present invention relates to a four-stroke engine in which a spark plug facing the combustion chamber is mounted on a cylinder head provided with a plurality of intake ports opening to the combustion chamber. Background technique [0002] Conventionally, such a four-stroke engine is known, for example, from Patent Document 1 and the like. [0003] (Patent Document 1) [0004] Japanese Patent Publication No. 5-71767. [0005] In the above-mentioned four-stroke engine of the prior art, since the intake air flowing into the combustion chamber from at least one of the plurality of air inlets collides with the spark plug and disperses in the combustion chamber, the mixed gas in the combustion chamber is stirred, and it is difficult to achieve lean combustion. Possibility of big fuel bill. Contents of the invention [0006] The present invention is proposed in view of this situation, and the purpose is to provide a four-stroke engine capable of perf...
