Document Type and Number:
Japanese Patent JP7112998
Kind Code:
B2
Abstract:
The utility model provides an internal combustion engine which can inhibit turbulence of airflow in an air suction hole and reduce adhesion of spray fuel. The internal combustion engine includes a cylinder head. The cylinder head includes: an intake hole connected to the combustion chamber and guiding air flowing into the combustion chamber; a fuel injection valve which extends from the valve body in the axial direction with a diameter smaller than that of the valve body and injects fuel from a nozzle at the front end into a space in the intake hole; an annular body which receives the valve body in the axial direction and forms a through hole for the nozzle; and a recess which is recessed from the inner surface of the suction hole, forms a space in the outer periphery of the nozzle in front of the annular body, and partially accommodates the nozzle. The internal combustion engine includes a bulging portion that expands from the inner surface of the intake hole upstream of the recessed portion based on the annular body.
