FIELD: engines and pumps.
SUBSTANCE: invention proposes an injector test and adjustment bench containing counter pressure device (8) allowing to create variable counter pressure to fuel injector, which varies similar to pressure of gases in an engine cylinder during injection, which differs by the fact that the counter pressure device consists of two plungers (10, 11), adjustment sleeves (12, 13) with counter pressure springs (14, 15) and bypass valve (19).
EFFECT: cheaper and simpler design of a bench.
