Title: Internal combustion engine using hydrogen as fuel
Inventor: INOUE SOKICHI
IPC: F02M21/02
Filed: 1994-06-08
Abstract: PURPOSE:To prevent atmosphere pollution ad restrict the waste of natural resources by mixingly injecting necessary amount of oxygen and gaseous hydrogen picked in an engine from a nozzle to a rotor combustion chamber, igniting by means of a ignition plug to convert the heat energy generated into torque by means of a rotor. CONSTITUTION:Gaseous hydrogen is formed by hydrolyzing and pyrolyzing methanol utilizing the exhaust of an internal combustion engine and a necessary amount of oxygen occupying about 30% of air is picked by means of a picking filter. The hydrogen and oxygen obtained (picked in the internal combustion engine) are mixedly injected from a nozzle to a rotor combustion chamber and ignited and burned by means of an ignition plug, and the generated heat energy is converted into torque by means of a rotor to be taken out as power. Since it is considered that water exists as steam in the exhaust, this is utilized to form hydrogen from methanol. This gas is cooled by water to be condensed, becoming pure water, which is electrolyzed to be reused.

Filed: 1997-06-19
Abstract: PROBLEM TO BE SOLVED: To improve the driving efficiency of an ultrasonic motor. SOLUTION: The side which comes into contact with the rotor 8 of an oscillator 6 is separated in its circumferential direction by a plurality of radial slits 12, for which a plurality of protruding small oscillating pieces 11 are disposed in an annular shape.
