Patent ID: 8225770

Claim:
A fuel injector assembly comprising: a modular fuel injector unit including a first fuel injector with a first seal, a second fuel injector with a second seal and a fuel distribution pipe fluidly communicating with the first and second fuel injectors to distribute a fuel to the first and second fuel injectors, with the first and second fuel injectors and the fuel distribution pipe being coupled together as a single installable unit; and a cylinder head side member including a first insertion hole with a first fitting section that receives the first seal and a second insertion hole with a second fitting section that receives the second seal; the first and second insertion holes of the cylinder head side member and the first and second seals of the first and second fuel injectors being arranged with respect to each other such that as the modular fuel injector unit is being mounted to the cylinder head side member by inserting the first and second fuel injectors into the first and second insertion holes formed in the cylinder head side member, respectively, 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.
