Abstract
An object of the present invention is to produce a difference in the pressure produced in a plurality of holes formed in a side part of a shield by a fuel injected from a fuel injection valve toward the side part, thereby the fuel flows easily into the shield by way of the holes as a result of this pressure difference. The present invention is a device comprising a heater G/P provided in a cylinder head C/H so as to be exposed to the inside of a cylinder, wherein the heater G/P is continuously heated and serves as an ignition assist source, a shield S whose side part SS is formed in a cylindrical shape covering the heater G/P at a specified interval from the surface of the heater G/P, a plurality of holes S/H formed in the side part SS of the shield S to afford connection between the inside and the outside thereof, a fuel injection valve IN provided in the cylinder head C/H, wherein the fuel injection valve IN has an injection hole IN/H for injecting the fuel toward the side part SS, and an axis line Lof the injection hole IN/H inclined relative to a perpendicular line Lperpendicularly extending from the side part SS to the injection hole IN/H.
