Patent ID: 7654233

Claim:
An engine device for an oxyhydrogen vehicle, comprising: an oxyhydrogen generator for electrolytically converting an electrolyte into oxyhydrogen gas; a fuel tank for storing combustible fuel; a first pipe unit connected to said oxyhydrogen generator; a second pipe unit connected to said fuel tank; an engine unit including a cylinder block, an intake manifold that is connected to said cylinder block, that is provided with passages, and that is further connected to said first pipe unit such that the oxyhydrogen gas generated by said oxyhydrogen generator is fed into said passages, and fuel injectors that are connected to said intake manifold, that are further connected to said second pipe unit, and that serve to inject the combustible fuel in said fuel tank into said passages, the oxyhydrogen gas from said first pipe unit being mixed with the combustible fuel from said fuel injectors in said passages to result in hybrid fuel that is supplied to said cylinder block; wherein said engine unit further includes an exhaust pipe connected to said cylinder block, and an oxygen content sensor for detecting oxygen content in exhaust gas from said cylinder block and flowing through said exhaust pipe; a gas flow sensor provided on said first pipe unit; a throttle provided on said first pipe unit; and a computer unit connected electrically to said gas flow sensor and operable so as to determine amount of the oxyhydrogen gas flowing through said first pipe unit; said computer unit being further connected electrically to said oxygen content sensor and being further operable so as to determine combustion state of said engine unit based on the oxygen content detected by said oxygen content sensor; and said computer unit being connected electrically to said throttle and controlling said throttle based on output of at least one of said gas flow sensor and said oxygen content sensor so as to regulate flow of the oxyhydrogen gas through said first pipe unit.
