Document Type and Number:
Japanese Patent JP2004519583
Kind Code:
A
Abstract:
The object of the invention is to provide an operating method of an internal combustion engine with critical water injection, in which the advantage of critical water is positively utilized to increase engine efficiency and output in addition to the reduction of the emission of nitrogen oxide and CO. It is characterized in that sub- or super-critical water of above 250° C. and above 10 MPa is injected during the compression or combustion stroke of the internal combustion engine by starting the injection before the fuel ignites in the compression stroke, particularly the injection is done so that said critical water interferes with the fuel spray injected into the combustion chamber, and the injection period is in the range of -90° C.~+30° C. from the top dead center crank position.
