摘要： Hydrogen gas from a hydrogen generator which creates hydrogen gas by the electrolysis of water or water vapor is supplied at the entrance to a catalyzer provided in an exhaust line. The catalyzer performs a catalytic reaction between hydrogen gas and nitrogen oxides to achieve decomposition into nitrogen gas and water vapor in the exhaust from an internal combustion engine. The nitrogen oxides are directly reduced with said hydrogen gas in a low temperature atmosphere not higher than 350.degree. C. to achieve efficient reduction in the nitrogen oxides. The improved method and apparatus provide a catalytic system with which the nitrogen oxides in the exhaust from a lean burnt engine or a diesel engine can be effectively reduced irrespective of the concentration of oxygen gas in the exhaust without impairing the good fuel economy of those engines.

摘要： An apparatus for efficiently purifying NOx in the exhaust gas or soluble organic substance in the exhaust gas from a diesel engine. A plurality of purification units are arranged in a housing, each of which is composed of a catalytic layer for reducing NOx and a cooling core for cooling the exhaust gas admitted through the catalytic layer. The multi-staged purification units are so constructed to admit the exhaust gas to flow therethrough. The catalytic layer in the form of a porous carrier such as a honeycomb structure carries catalytic components. Upon purifying soluble organic substance in the exhaust gas from a diesel engine, the catalytic components carried on the catalytic layer serve to efficiently purify such substance, as well as inhibiting the reaction to form sulfate.

摘要： A direct injection type internal combustion engine has a piston reciprocatably fitted in the bore of a cylinder block defining a combustion chamber together with the cylinder block and a cylinder head. A main recess is formed in the combustion chamber for accelerating the swirl of intake air which is prepared and introduced by an intake device. At least one auxiliary recess is formed in the main recess and is arranged in the direction of the intake air swirl and in the direction of the fuel injection of a fuel injector for generating a secondary swirl different from the intake air swirl and for generating turbulence between the two swirls. Thus, the introduction of air into the fuel droplets fed from the fuel injector is promoted by the intake air swirl and the secondary swirl so that the combustion efficiency of the internal combustion engine is improved.

摘要： An intermittent type swirl injection nozzle providing substantially improved spray characteristics while being easy to manufacture and install. The nozzle includes a nozzle body and a needle valve slidably disposed in a guide hole of the nozzle body with a spray hole communicating a body seat formed inside the nozzle body and the forward end of the needle valve. A swirl passage is provided around the needle valve for giving a swirl flow influence around the axis of the needle valve to fuel when the needle valve is lifted from the body seat. A straight passage is provided in a portion where the inner wall of the guide hole and the needle valve make sliding contact for giving the fuel a straight flow influence in the axial direction of the needle valve. The two flows are joined prior to passing through the spray hole.

摘要： Disclosed are a turbulence generating method for an internal combustion engine and an internal combustion engine for carrying out that method. Main and auxiliary recesses communicating with each other are formed by at least two projections in the combustion chamber of a reciprocating internal combustion engine, which is defined by a piston, a cylinder head and a cylinder block. A swirling mechanism for swirling the intake air is disposed in an intake mechanism for supplying the intake air into the combustion chamber. A swirl of intake air is generated in the main recess by the swirling mechanism and is accelerated and introduced into the main recess as the piston rises. A turbulent layer is formed while the swirl is converted occasionally into turbulences by the projections. Secondary swirls other than the main swirl are generated in the auxiliary recesses. Turbulences are further generated between the swirl and the secondary swirls thereby to improve combustion efficiency.
