Abstract
An electrically heated heating member (13) is arranged in a cavity formed in the top surface of the piston (2) and fuel is injected from the nozzle (9) of the fuel injector (8) toward the heating surface (15) of the heating member (13) in the form of a continuous fluid stream. This injected fuel strikes the heating surface (15) in the form of a continuous fluid stream and receives heat from the heating surface (15) to atomize and simultaneously disperses inside the cavity (7). Next, the atomized fuel is self-ignited.

A hot surface impact ignition type internal combustion engine, comprising:
- a piston positioned at a top center portion of a combustion chamber and having a top face in which a cavity is formed, the cavity having a central portion;
- and
- an electrically heated heating member arranged in the combustion chamber and positioned at the central portion of the cavity of the piston, the heating member having a heating surface which is formed substantially flat and which extends in a direction perpendicular to an axial line of injected fuel, wherein fuel is injected from a fuel injector toward the heating surface of the heating member in the form of a continuous fluid stream, the fuel striking the heating surface in the form of an unatomized fluid.
A hot surface impact ignition type internal combustion engine, comprising:
- a piston positioned at a top center portion of a combustion chamber and having a top face in which a cavity is formed, the cavity having a central portion;
- and
- an electrically heated disc-shaped heating member supported through a support member by a cylinder head and arranged in the combustion chamber and positioned at the central portion of the cavity of the piston, the heating member having a heating surface which extends in a direction perpendicular to an axial line of injected fuel, wherein fuel is injected from a fuel injector toward the heating surface of the heating member in the form of a continuous fluid stream, the fuel striking the heating surface in the form of an unatomized fluid.
