摘要

The apparatus for measuring the parameters of a work diagram of piston machines comprises, connected to one another, a current crankshaft rotation angle counter having inputs coupled, via a crankshaft angular position pulse former and a top dead centre pulse former, to an angular mark sensor, and a decoder decocing top dead centre signals. To the latter is coupled an input of a flip-flop of an analysis and control. This has a counter having an input coupled, via a main coincidence gate, to one of several pressure sensors in cylinders of piston machines, in accordance with the cylinder selected for indication, and a logical circuit having an input coupled to a reversible counter connected to a flip-flop. The apparatus also comprises a series circuit including a decoder for decoding bottom dead centre signals coupled to the reversible counter and flip-flop. A cycle length counter and a main flip-flop are coupled to the bottom dead centre decoder and to an AND gate.
