FIELD: engine manufacturing; internal combustion engines. ^ SUBSTANCE: invention relates to testing facilities of internal combustion engines. Proposed device contains unit for fastening nozzles with injection detectors and two groups of nozzles communicating independently through hydraulic distributors, and filters with two metering chambers with common piston connected with linear displacement converter connected to control and indicator unit connected with injection detector and coils of hydraulic distributors. Device is furnished additionally with pneumohydraulic accumulator with fuel level transmitter and shutoff valve with contracting device. Pneumohydraulic accumulator is connected by common hydraulic line through hydraulic distributors with both metering chambers and, through contracting device and shutoff valve, to drain main line. Level transmitter and coil of shutoff valve are connected with control and indicator unit. ^ EFFECT: reduced errors in measuring fuel pump cyclic deliveries. ^ 2 cl, 2 dwg |
