Title: Cycle engine for preserving various kinds of energy
Inventor: TANIGAWA HIROYASU
IPC: F01N3/04
Filed: 2001-04-02
Abstract: PROBLEM TO BE SOLVED: To solve such a problem that present reciprocating internal combustion engines are not usable for automobiles though the ratio of thermal energy radiated at a top dead center is maximum for the present reciprocating internal combustion engines, minimum at approx. 15% for a small-sized gasoline engine with a radiation thermal energy loss of approx. 50% when the engine is not rotated, and maximum at a radiation thermal energy loss of approx. 20% when the engine is not rotated and a thermal efficiency of 55% for a marine large-sized diesel engine with maximally delayed combustion. SOLUTION: A combustion is formed with two stages. A first stage reduced diameter main combustion chamber superheated steam water injection NOx non-separation combustion is completed by a generally closed container stoichiometric air/fuel ratio to super-lean perfect combustion, and the maximum combustion pressure is moved closely to eight times a compression pressure. Only the timing of discharge of thermal energy is delayed, and condensed water is allowed to dynamically pressure react with the minimum frictional loss so as to increase a thermal efficiency to approx. 70%. The unburned amount is moved closely to zero by the increased diameter combustion chamber super-high speed agitating two-stage combustion, and the temperature of the exhaust gas as the combustion gas of a high-pressure and low temperature large mass is lowered remarkably.  The generally all exhaust of the combustion gas such as CO2 is improved so as to be dissolved into a condensed water before discharge to minimize the exhaustion of the combustion gas such as CO2.
