摘要： An accumulator fuel injection apparatus for an internal combustion engine is provided which includes a solenoid-operated fuel injector. The fuel injector includes a solenoid valve and a needle valve. The solenoid valve establishes and blocks fluid communication between a pressure control chamber supplied with fuel pressure from a fuel inlet and a drain passage formed in a valve body to change fuel pressure within the pressure control chamber, thereby bringing the needle valve into engagement with and disengagement from a spray hole. The fuel injector also has a first orifice disc and a second orifice disc installed within the valve body. The first orifice disc has formed therein a first orifice which provides a first flow resistance to fuel flowing from the fuel inlet into the pressure control chamber. Similarly, the second orifice disc has formed therein a second orifice which provides a second flow resistance smaller than the first flow resistance to the fuel flowing out of the pressure control chamber into the drain passage. The second orifice disc is disposed on the first orifice disc so that thicknesswise directions thereof coincide with each other.

摘要： A fuel injector is provided which has an improved structure capable of adjusting fuel jet characteristics such as the quantity of fuel to be injected to an engine and a fuel injection time lag after the fuel injector is assembled. The fuel injector includes an air gap adjusting screw and a spring pressure adjusting screw. The air gap adjusting screw serves to change an air gap between a stator and an armature of a solenoid valve to adjust the quantity of fuel to a target one. The spring pressure adjusting screw serves to change a spring pressure urging a valve in a spray hole-closing direction to regulate a spray hole open duration, thereby adjusting the fuel injection time lag or the quantity of fuel.

摘要： In a metal catalyst converter configured of the metal catalyst carrier that holds the catalyst into the honeycomb body created by alternately winding flat sheet and corrugated sheet, a plurality of slit matrix that extend in the direction perpendicular to the exhaust gas direction were arranged on at least one part of the upstream side of the exhaust gas passage. By that a low heat capacity and high heat transfer area in regard to the downstream side of the exhaust gas passage was formed. The upstream portion of the metal catalyst converter on which slit matrix was formed was configured to be covered by outer casing having an air insulation layer. The upstream side of this outer casing was held and fixed to the exhaust gas passage.
