The study of the F-34 aviation fuel used to power a diesel engine requires an extensive testing programme be carried out in the steady and transient states of the engine operation. The researches of the engines are expensive therefore, the tests can be also performed on the non-engine-based stand at a lower price. The design of the non-engine-based test stand and the methodology of the engine injection system testing follow the AEP-5 qualifying test has been described in the paper. The measurement methods used on the stand and the selected measurement results are presented. The tests have included checking the changes of three basic sets of the injection systems that may be subject to wear during the operation of the system. This applies to the following assemblies: jet needle - injection nozzle body, delivery valve plug - carrier, injection pump plunger and barrel.
