    • A cooling apparatus for the internal combustion engine of a motor vehicle includes a cooling-air fan (10), a radiator assembly (2) and a fan shroud (18) which extends from a fan ring (9), enclosing the cooling-air fan, as far as the radiator assembly. In order, with given dimensioning of the radiator assembly (2) and cooling-air fan (10), to increase the cooling capacity, the fan shroud (18) forms, in the part (12) which projects laterally beyond the projection of the cooling-air fan (10), a vertical flow duct (23) and, in the part (11) which projects beyond the radiator assembly (2), a collecting chamber (22) which is in flow connection with the vertical flow duct (23).

    • A fuel injection nozzle for internal combustion engines comprises a nozzle body (1) and a nozzle needle (5) guided therein. The nozzle body (1) terminates in a nozzle cap (3) in which ejection bores (4) are provided and which forms at the inside a conical valve seat (6) against which the nozzle needle (5) is pressed. The nozzle needle (5) lifts under the pressure of the fuel supplied in a first lifting phase against the force of a spring (8) off the valve seat (6) and bears on a stop (19). This stop (19) is limitedly displaceable in a second lifting phase against the force of a further spring (9). To reduce the hydrocarbon emissions in the exhaust gases of the internal combustion engine and diminish ignition noise, the generated surface (M) of the imaginary cylinder formed in extension of the ejection bore (4) between the inner edge (R) thereof and the surface of the nozzle needle (5) lifted off the valve seat in the first lifting phase is made smaller than the cross-section of the ejection bore (4).
    • 一种用于内燃机的燃料喷嘴,包括在其中引导的喷嘴体(1)和喷嘴针(5)。 喷嘴主体(1)终止于其中设置有喷射孔(4)的喷嘴盖(3),并且在内侧形成锥形阀座(6),喷嘴针(5)被挤压到该锥形阀座。 喷嘴针(5)在第一提升阶段供应的燃料的压力下抵抗离开阀座(6)的弹簧(8)的力提升,并承载在止动件(19)上。 该止挡件(19)在第二提升阶段中有可能抵抗另一弹簧(9)的力而移位。 为了减少内燃机的废气中的碳氢化合物排放并降低点火噪声,在喷射孔(4)的内边缘(R)与表面的内表面(R)之间形成的假想气缸的产生表面(M) 在第一提升阶段中离开阀座的喷嘴针(5)的尺寸小于喷射孔(4)的横截面。
