摘要： A vibration isolation fuel rail mounting arrangement is configured for in-plane shear type damping by spacing the mid-width points of the elastomer compression areas of two stacked-layer isolators away from the central fastener axis by a distance between about 1.5 times the bolt diameter and about 3.0 times the bolt diameter.

摘要： In a mould (13) a corrosion-resistant first alloy (10) is arranged at least in an outer area which is to constitute the outer surface of a nozzle around the nozzle bores (4). A second alloy (11) is used in another area of the nozzle. The materials in the mould are treated by isostatic pressing into a consolidated material. The boundary area between the two alloys (10, 11) is free of cracks.

摘要： A coating structure (1, E) for a metal member (10) includes a surface-smoothing layer (11, 13, 14) formed on the metal member (10) for smoothing a surface of the metal member (10), and a fluorine-based film (12) formed on the surface-smoothing layer (11, 13, 14). The fluorine-based film (12) can be formed by applying a fluorine-containing solution (120) on the surface-smoothing layer (11, 13, 14), and by drying the fluorine-containing solution (120). The coating structure (1, E) can be suitably used for a fuel injection nozzle (7).

摘要： The disclosed valve has an injector plate (23) arranged downstream of a valve seat (29). The injector plate (23) is characterised in that it has a plurality of narrow fuel discharge slots (40) that are arranged in a star shape in the radial direction but have no common contact point. This arrangement allows fuel to be finely sprayed without requiring additional energy. The breaking down into smallest droplets also results in a further reduction of the exhaust gas emission of an internal combustion engine and in a reduction of fuel consumption. This valve is particularly useful for fuel injection systems spark-ignited internal combustion engines with high compression ratio of the mixture.

摘要： The invention relates to a method for producing a valve piece (108) for a fuel injector (100), having a region on the valve piece (108) which forms a valve seat (115), wherein the valve piece (108) has, as its basic material (119), a preferably hardened steel, of which the surface, in the region forming the valve seat (115), is coated with a carbon layer (130) of greater hardness than the basic material (119). The invention makes provision for a supporting layer (120) to be formed between the basic material (119) and the carbon layer (130), wherein the hardness of the supporting layer (120) is at least equal to that of the basic material (119).

摘要： The present invention relates to a structure and method for coating a nozzle for a fuel injection valve. The structure for coating a nozzle for a fuel injection valve, said coating reducing the frictional resistance of a nozzle needle contacting a sheet part of a nozzle body having an injection hole, includes: a Cr coating layer deposited on the outer surface of the nozzle needle of the fuel injection valve; a CrN coating layer deposited on the outer surface of the Cr coating layer; and a WCC coating layer deposited on the outer surface of the CrN coating layer. Here, the hardness of the CrN coating layer is relatively greater than that of the WCC coating layer. According to the present invention, wear resistance and impact resistance may be improved by means of the coating layer being formed on the outer surface of the nozzle needle so as to prevent impacts, resulting from collisions between a front end of the nozzle needle and a sheet part, from being transferred to the nozzle needle. Also, the hardness of the CrN coating layer is greater than that of the WCC coating layer so as to further improve wear resistance and impact resistance. Thus, changes in the fuel injection properties of the fuel injection valve over time may be reduced so as to improve the fuel injection valve.
摘要翻译：本发明涉及一种涂覆燃料喷射阀喷嘴的结构和方法。用于涂覆燃料喷射阀喷嘴的结构，所述涂层降低与具有喷射孔的喷嘴体的片部分接触的喷嘴针的摩擦阻力，包括：沉积在喷嘴针的外表面上的Cr涂层的燃料喷射阀; 沉积在Cr涂层的外表面上的CrN涂层; 以及沉积在CrN涂层的外表面上的WCC涂层。这里，CrN涂层的硬度比WCC涂层的硬度要大。根据本发明，可以通过形成在喷嘴针的外表面上的涂层来改善耐磨性和耐冲击性，从而防止由喷嘴针的前端与片之间的碰撞引起的冲击部分，从转移到喷嘴针。此外，CrN涂层的硬度大于WCC涂层的硬度，从而进一步提高耐磨性和耐冲击性。因此，可以减少燃料喷射阀的燃料喷射特性随时间的变化，从而改善燃料喷射阀。
