摘要： A fuel injector assembly includes a modular fuel injector unit and a cylinder head side member. The modular fuel injector unit includes a first fuel injector with a first seal, a second fuel injector with a second seal and a fuel distribution pipe coupled together as a single installable unit. The cylinder head side member includes a first insertion hole with a first fitting section and a second insertion hole with a second fitting section. The first and second insertion holes and the first and second seals of the first and second fuel injectors are arranged such that as the modular fuel injector unit is being mounted to the cylinder head side member, the first seal undergoes a maximum compressive deformation in the first fitting section at a time that does not coincide with a time that the second seal undergoes a maximum compressive deformation in the second fitting section.
