ABSTRACT:
An engine structure (12) wherein a fuel injector nozzle (11) is retained in accurate preselected association with the cylinder head (16) by an improved clamp (20). The clamp is associated with a force-applying device (24) and the nozzle head (13) so as to provide an accurate transfer of force from the force-applying device (24) to the nozzle parallel to the longitudinal axis (20) of the nozzle and in a manner accurately positioning the nozzle about its longitudinal axis. The clamp is associated with the force-applying device and the nozzle head so as to have non-surface engagement between the force transfer portions (21,28, 31,19, and 34,35) and in the illustrated form, utilizes line contact force transfers therebetween. The line contacts are preselected so as to be parallel to each other in providing the desirable accurate force transfer.
