Title: Eddy-current chamber type diesel engine
Inventor: TANAKA TOSHIAKI
IPC: F02M61/18
Filed: 1981-09-16
Abstract: PURPOSE:To reduce NOX and HC in the exhaust gas in such a way that one injection port of a multiple-injection port nozzle is directed to the axial line of an auxiliary communicating port, fuel jetted in an eddy-current chamber is diffused, and at the initial stage of combustion, rarefied combustion gas is jetted through a main communicating port into a main combustion chamber. CONSTITUTION:Spray jetted through two auxiliary inspection ports 13, 14 to the plane Y among fuel spray jetted through a three-injection port nozzle 11 into an eddy-current chamber 7 is diffused on both sides in the eddy-current chamber 7, and most of the spray which has been jetted through a main injection port 12 toward an auxiliary communicating port 6 comes into a main combustion chamber 4 within a cycle for ignition lag. In consequence, the inside of the eddy-current chamber 7 becomes a fuel rarefying zone 15 in which there is more air rate than fuel, and its both sides become fuel super- condensed zone 16. Subsequently, fuel in the main combustion chamber 4 and in the eddy-current chamber 7 is ignited, and initial combustion starts. As a piston 2 is coming down, combustion gas in the rarefying zone 15 comes through a main communicating port 5 into the combustion chamber 4. Since the gas is involved in high temperature, it makes combustion in the main combustion chamber 4 favorable, and can reduce NOX and HC in the exhaust gas.

Abstract: PURPOSE:To enhance the dispersion stability of semiconductor minute particles by making said particles hydrophobic by dispersing the semiconductor minute particles in a cyclic organosiloxane solution and irradiating the formed dispersion with light having a specific wavelength. CONSTITUTION:Semiconductor minute particles such as TiO2 minute particles are dispersed in a solution of cyclic organosiloxane represented by formula I (wherein R1 and R2 are H, an alkyl group, a phenyl group, an alkoxyl group or a phenyl group and n is 3 - 5). Next, the obtained dispersion is irradiated with light of a wavelength having energy equal to or more than the band gap of the semiconductor to coat the surfaces of the semiconductor minute particles with a siloxane polymer. As cyclic organosiloxane, 1, 3, 5-tetramethylsiloxane is especially pref. used from the aspect of reactivity. By this method, the surfaces of the minute particles are made hydrophobic and the dispersed state of the minute particles is stabilized. Further, the specific gravity of the minute particles is made apparently low and the sedimentation of the minute particles having high specific gravity is suppressed.
