ENGINE

Japanese Patent JP2012211594

A

To provide an engine that has a degree of freedom in a layout position of an ignition plug, and can almost uniformly disperse flares injected from injection holes.

The ignition plug spark-ignites mixed air flowing from a combustion chamber 1 via a plurality of the injection holes 10 in an ignition point P and combusts it, the flares L formed by combustion are led to the plurality of injection holes 10, injected to the combustion chamber 1 and combust the mixed air in the combustion chamber 1, diameters of the plurality of injection holes 10 are set the same, the plurality of injection holes 10 are formed at a plurality of divided regions A to D, respectively, which are formed by dividing the combustion chamber 1 by a linear line with the ignition point P as a center in a cross section view orthogonal to the center axis of the combustion chamber 1, and the injection holes formed at the plurality of divided regions A to D, respectively, are set to be larger in an installation number as an area of the divided region becomes larger in the cross section view.
