摘要： An engine system of the invention comprises an internal combustion engine; a carburetor; an exhaust gas recirculation system; an exhaust gas treatment device; and a source of secondary air, in which there is provided a fluid network which interconnects the source of secondary air, the engine exhaust system at a position upstream of the exhaust gas treatment device and the exhaust gas recirculation system at a position upstream of an exhaust gas recirculation valve and there is also provided an air injection control valve fluidly disposed in the fluid network intermediate the source of secondary air and the exhaust gas recirculation system. The air injection control valve is adapted to selectively permit and prevent the admission of air to the exhaust gas recirculation system. A controller for the air injection control valve is also disclosed which comprises a detector that generates as an output signal a first signal responsive to urban driving conditions which are empirically determined to occur when the motor vehicle is driven in urban areas and a second signal responsive to rural driving conditions which are empirically determined to occur when the motor vehicle is driven in rural areas. The controller causes the air injection valve to permit the admission of air to the EGR system when the detector detects the rural driving conditions.

摘要： In order to avoid the formation of smoke and HC when the compression ratio of a swirl chamber type Diesel engine is lowered either by design or by operation in rarified atmospheres, the fuel injector is located on one side of the center axis of the swirl chamber so as to maximize the distance for which the injected fuel can travel before contacting a wall of the chamber and the auxiliary transfer port through which a fraction of the injected fuel is fed to the main combution chamber is arranged so that the axis thereof intersects the axis of the fuel injector and therefore the trajectory along which fuel is injected, at a point defined within the swirl chamber per se and on the opposite side of the center axis with respect to the fuel injector.

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。
