УСТРОЙСТВО ДЛЯ ИЗМЕРЕНИЯ НЕРАВНОМЕРНОСТИ ПОДАЧИ ТОПЛИВА

摘要

FIELD: engine engineering. ^ SUBSTANCE: device for measuring irregularity of fuel supply has case provided with measuring chamber which is formed by drain electromagnet valve. Valve is loaded with spring, burners and plunger; plunger has opposing spring. Unit for measuring level of signal has to be elastic plate with strain-gauge transducers glued on the top of the plate. Transducers are connected to each other to form bridge circuit. Analog-digital converter is connected to unit signal measuring unit through computer. Electronic unit is provided with transducer and connected to electromagnet valve. Device is additionally provided with fuel dump and relief valves mounted in series. ^ EFFECT: simplified design; improved precision of measurement; higher precision of evaluation of irregularity in fuel injection. ^ 4 cl, 4 dwg
