Abstract: Conventional apparatus for testing fuel injectors are inconvenient, difficult to adapt to different injectors and are quite expensive. The subject apparatus overcomes these problems by providing a testing apparatus which has a fuel manifold with internal passages to an interchangeable adaptor. The interchangeable adapter provides for different sizes of fuel injectors and changes in access to their fuel ports. The apparatus includes visual inspection means that can readily changed to a measuring means for measuring the fuel being injected as well as to continuously observe the injection spray. The entire apparatus is self-contained in a manner that reduces external leakage of fuel during testing and is under control of an electronic controller that simulates engine operation of a fuel injector.

Abstract: Prepackaging the various components of an engine cylinder assembly as an exchange or overhaul kit is useful in servicing or overhauling a single cylinder of a multiple cylinder engine. The heretofore known devices for holding the components of the engine cylinder assembly together were primarily used with small engines where the weight of the components was sufficiently low so as to not cause any handling difficulties. The subject apparatus includes a pair of brackets which positively grippingly engage the flange of the cylinder liner and a lifting element which is releasably attached to the piston with bolts threaded into threaded holes in the piston such that a portion of the brackets is sandwiched between the lifting element and the piston. The apparatus is positively engaged with the components of the engine cylinder assembly and positively maintains the components in fixed relationship with one another.
