摘要： A mechanical system that forms a cam follower or a rocker arm. The mechanical system includes a support element, a pin extending between two opposite ends along a first axis, and a roller mounted on the pin, movable in rotation relative to the pin around the first axis and adapted to roll on a cam. The support element further comprises an insert having holding members supporting the pin ends, provided with cut-outs having a shape complementary to the shape of the pin-ends, for assembling pin with insert by quarter-turn around the first axis. The pin ends each have a flat surface and an external surface. A first dimension of each pin end, measured perpendicularly to the flat surface, between the flat surface and the external surface of the pin end, is higher than half the outer diameter of the pin ends.

摘要： A fuel injector assembly for an emissions-based EMD 710 locomotive dieselengine. The fuel injector assembly includes a needle slidably positioned within a bore of a valve body of the injector assembly, where fuel pressure introduced into a bore chamber causes the needle to open a spray tip. A spring mounted within the bore forces the needle to close the spray tip when the fuel is not being applied. The spring is a dead coil spring including inactive coils where at least portions of the coils at both ends of the spring are in intimate contact with each other so as to reduce spring wear during operation of the assembly. Because the dead coil spring has reduced wear, the VOP set point of the fuel injector assembly can be reduced, which reduces NOx emissions.
摘要翻译：一种用于基于排放物的EMD 710机车柴油发动机的燃料喷射器组件。燃料喷射器组件包括可滑动地定位在喷射器组件的阀体的孔内的针，其中引入孔腔的燃料压力导致针打开喷嘴。安装在孔内的弹簧迫使针头在燃料未被施加时关闭喷嘴。弹簧是包括惰性线圈的死螺旋弹簧，其中弹簧两端的线圈的至少部分彼此紧密接触，以便在组件的操作期间减少弹簧磨损。因为死螺旋弹簧具有减少的磨损，所以可以减少燃料喷射器组件的VOP设定点，这降低了NOx排放。
