FIELD: mechanical engineering; internal combustion engines; testing facilities. SUBSTANCE: proposed fuel pump test stand contains housing with functional units - fuel pump mounting unit, fuel feed unit, metering unit with metering vessels and counterpressure unit, and measuring unit with linear and angular displacement sensors, all interconnected and mounted on common base. Fuel pump test stand has thermostatic control device of fuel feed unit, metering unit and counterpressure unit. Said device is made in form of outer envelopes enclosing working fuel container, outlet pipelines of pump under testing, metering vessels of metering unit and supply pipelines of counterpressure unit. EFFECT: improved accuracy of results of fuel pump tests owing to introduction of fuel thermostatic control device. 25 cl, 3 dwg
