为了节省能源,英国Lucas(鲁卡斯)-CAV公司,研制了一种柴油机用的微型喷油咀,已于1980年成批装用。它比传统的喷油咀结构要小得多,因而可以减小汽缸盖,以致于减轻发动机的重量。微型喷油咀总重52克,总长65毫米,没有排油管,更换简便。用φ14毫米的标准螺纹拧到汽缸盖上。由于制造公差很小,因而不需要改变压缩弹簧的预应力,就能 In order to save energy, Lucas (UK) -CAV company, developed a miniature diesel injector nozzle, which was put in bulk use in 1980. It is much smaller than the traditional nozzle structure, so you can reduce the cylinder head, so as to reduce the weight of the engine. Micro-nozzle total weight of 52 grams, a total length of 65 mm, there is no drain, easy to replace. Screw to cylinder head with standard φ 14 mm thread. Because of the small manufacturing tolerances, there is no need to change the prestressing force of the compression spring
