description systems for measuring pressure and evaluating controlled parameters in diagnostic equipment for internal combustion engine, heating equipment and piston-cylinder groups. SUBSTANCE: system includes pressure pickup, analog-to-digital converter having clock pulse generator connected in series, resistor matrix, operational amplifier and register. Apparatus includes in addition code converter, decoder, two digital indicators and three light-emitting diode based indicators of engine condition. Gate-pulse input of register is connected with output of operational amplifier; two other inputs of register - with outputs of pulse counters; direct input of operational amplifier is connected though resistor matrix with outputs of pulse counters; other input of operational amplifier is connected with output of pressure pickup. Code converter is in the form of two microcircuits having read only memory and comparator. Input of code converter is connected with output of register; its outputs - with input of decoder and digital indicator. Light emitting diodes are connected with output of decoder. Apparatus provides pressure measuring at final stage of compression cycle and evaluation of state of cylinder-piston group and controlled parameters. EFFECT: enhanced accuracy and reliability of controlled parameter evaluation. 2 dwg
