ABSTRACT:
The invention provides an in-cylinder injection type internal combustion engine that is capable of controlling gas flow velocity in the vicinity of an ignition part of a spark plug and maintaining an air-fuel mixture suitable for ignition for a long time. The engine includes deflecting parts28that have a passage25located on a wall face of a combustion chamber between an injection part11and an ignition part17, and deflect a portion of the fuel injected from the injection part11to indirectly direct the fuel to the vicinity of the ignition part. Due to the above construction, there is a difference in reaching timing between direct and indirect routes, and moreover a flow velocity of gas that reaches the ignition part is reduced by fuel deflection. An air-fuel mixture suitable for ignition therefore remains in the vicinity of the ignition part for a long time.
