摘要： A fuel injection nozzle for an internal combustion engine includes a hollow nozzle body and a valve member liftably disposed in the nozzle body. The nozzle body has an orifice extending from the inside to the outside thereof. The valve member closes and opens the inner end of the orifice in accordance with lift of the valve member. Fuel can flow through the orifice to be injected into the engine when the valve member opens the inner end of the orifice. A nozzle geometry causes the rate of fuel injection to increase through a plateau as the valve member is lifted.

摘要： A fuel injection nozzle for an internal combustion engine includes a hollow nozzle body and a valve member liftably disposed therein. The nozzle body and the valve member define a space therebetween through which fuel is supplied to an orifice in the nozzle body. The valve member contacts the nozzle body at a position to block communication between the space and the orifice when the valve member is in the unlifted position. Fuel enters the orifice from the space as the valve member lifts. The valve member and nozzle body have opposing surfaces establishing a gap between the space and orifice. The gap has a cross-sectional area smaller than that of the orifice that remains constant as the valve member lifts through a predetermined range so that the rate of fuel injection increases through a plateau as the valve member lifts to a position above the predetermined range.
摘要翻译： 一种用于内燃机的燃料喷射喷嘴包括中空喷嘴体和可升降地设置在其中的阀构件。 喷嘴体和阀构件在其间限定了一个空间，燃料通过该空间供应到喷嘴体中的孔口。 当阀构件处于未开启位置时，阀构件在一个位置处接触喷嘴体，以阻挡空间和孔口之间的连通。 当阀构件升起时，燃料从空间进入孔口。 阀构件和喷嘴体具有在空间和孔口之间建立间隙的相对表面。 间隙的截面面积小于孔口的横截面面积，其随着阀构件升高预定范围而保持恒定，使得当阀构件升高到高于预定范围的位置时，燃料喷射速率通过平台升高。

摘要： An exhaust purification apparatus includes a regenerative burner for repetitively regenerating a trap element located in the exhaust system of an internal combustion engine. The regenerative burner has a combustion chamber adapted to permit flow of exhaust gas from the engine exhaust conduit to the trap element. A hollow member is disposed within the combustion chamber to define an evaporation chamber therein. The hollow member has a side wall formed with a number of flame holes to permit fluid flow from the evaporation chamber into the combustion chamber. The evaporation chamber has a supply of air-fuel mixture through a mixture conduit having an end terminating in a discharge outlet opening into the evaporation chamber. The mixture conduit has a portion extending through the combustion chamber to promote fuel evaporation during a trap regeneration operation.

摘要： A fuel supply control device is disclosed wherein, as pressure of fuel from a fuel injection pump increases, a piston responsive to fuel pressure temporarily reduces or shuts off initial flow of fuel from the pump to a fuel injector through a series of fuel passageways. A second piston may be provided in a passageway to control movement of the first piston such that when the engine operates under relatively low loads at low speed, the second piston causes the first piston to restrict fuel flow. When the engine operates at relatively high speeds and high loads, the second piston cooperates with the first piston to feed fuel to the injector at high pressure.
