A fuel injector includes a nozzle body to be inserted into a fuel injector receiving bore along a nozzle body axis; a valve housing; and a locating pin extending from the valve housing along a locating pin axis. The locating pin axis is eccentric to the nozzle body axis. The locating pin has a width in a first direction radially relative to the nozzle body axis and through the locating pin axis and a length in a second direction perpendicular to the width such that the width is less than the length. The locating pin includes a first crush rib and a second crush rib which are diametrically opposed at the length of the locating pin and such that the first crush rib and the second crush rib plastically deform when inserted into the locating bore, thereby preventing rotational movement of the fuel injector about the nozzle body axis.

A fuel injector includes a nozzle body configured to be inserted into a fuel injector receiving bore of the internal combustion engine along a nozzle body axis; a valve housing held in fixed relationship to the nozzle body; and a first locating pin and a second locating pin each extending from the valve housing. The first locating pin extends from a first locating pin fixed end which is fixed to the valve housing to a first locating pin free end. The second locating pin extends from a second locating pin fixed end which is fixed to the valve housing to a second locating pin free end. The first locating pin and the second locating pin elastically deform when inserted into the bore, thereby preventing rotational movement of the fuel injector about the nozzle body axis.

A method for forming a fuel cell assembly including the pre-final-assembly step of forming a plurality of fuel cell sub-assembly modules, each module including a predetermined number of individual fuel cell repeating units, for example, ten. Each module may be leak and performance tested and certified prior to inclusion in the final fuel cell stack, thus limiting potential rework to only an individual module and only before assembly of the final stack. Preferably, each module is assembled on an assembly fixture having alignment rods, using a combination of resilient gasketing and RTV to seal between the elements. The assembled module is then placed under compression while the silicone is cured.

A fastening arrangement for connecting a first member to a second member which has a threaded bore is provided which includes a bolt having a head on one end and an attached shank with a threaded portion, a flange connected with the first member, the flange having a support surface for supporting the bolt head, and a bore intersecting the support surface allowing for penetration of the bolt shank, the bore also having at least two radially inward protruding guides for centering the bolt shank within the bore, and at least one compliant finger integrally formed and connected with the flange which by insertion of the bolt is deformed to a position to compliantly bias the bolt shank against at least one of the guides and to also retain the bolt shank within the bore.

A direct acting hydraulic valve lifter features in a preferred embodiment a follower assembled with a thin wall metal shell and a light plastic baffle to support a lash adjusting hydraulic element assembly. An inlet riser chamber has sufficient cross section to minimize oil flow restriction in cold oil conditions. Dead space between the shell and baffle is filled with a strong lightweight foam to support and retain the baffle and displace oil for low mass.
