[0062] refer to figure 1 and figure 2 , the first exemplary embodiment of the present invention will be described in detail.
[0063] figure 1 A system of a hydrogen-using internal combustion engine 2 (hereinafter simply referred to as "engine") constructed according to the first embodiment of the present invention is schematically shown. The engine 2 of the present embodiment includes a plurality of cylinders (in figure 1only one of the cylinders is shown). Each cylinder of the engine 2 has a piston 8 , and a combustion chamber 10 whose volume is repeatedly increased and decreased according to the vertical movement of the piston 8 is formed in each cylinder. An intake passage 4 and an exhaust passage 6 are connected to the engine 2 , air is supplied to the combustion chamber 10 of each cylinder through the intake passage 4 , and combustion gas (or exhaust gas) is discharged from the combustion chamber 10 through the exhaust passage 6 . In the engine 2, an intake valve 1...

[0089] refer to image 3 and Figure 4 , the second exemplary embodiment of the present invention will be described in detail.
[0090] image 3 A system of a hydrogen-using internal combustion engine (hereinafter simply referred to as "engine") constructed according to a second embodiment of the present invention is schematically shown. The engine of this embodiment has an engine 2 . The construction of the engine 2 is basically the same as that in the first embodiment, and thus will not be described here. exist image 3 in, with figure 1 The same reference numerals as used in are used to identify the same elements or components as in the engine of the first embodiment.
[0091] In the second embodiment, liquid hydrocarbon fuel such as gasoline is stored in the fuel tank 30 . The fuel supply passage 34 connects the fuel tank 30 and the in-cylinder injector 18 . The hydrocarbon fuel in the fuel tank 30 is sucked up by the fuel pump 32 arranged in the fuel supply passag...

[0109] refer to Figure 5 and Figure 6 , the third exemplary embodiment of the present invention will be described in detail.
[0110] Figure 5 A system of a hydrogen-using internal combustion engine (hereinafter simply referred to as "engine") constructed according to a third embodiment of the present invention is schematically shown. The engine of this embodiment has an engine 2 . The construction of the engine 2 is basically the same as that in the first embodiment, and thus will not be described here. exist Figure 5 in, with figure 1 and image 3 The same reference numerals used in are used to identify the same elements or components as in the engine system of the first and second embodiments.
[0111] In the third embodiment, hydrogen-mixed fuel in which hydrogen gas is contained in the form of fine bubbles in liquid hydrocarbon fuel such as gasoline is stored in the fuel tank 30 . However, the third embodiment differs from the first embodiment in that the hydrog...
