Indiscope-A New Combustion Pressure Indicator with Washer Transducers

As the New Pressure Indicator is easily installed on running cars, without altering any part of the engines in question, one can observe the real working behaviour of the engines, transient as well as steady-state, and not only in laboratories but also on open roads.

Some examples of indicator diagrams, unfamiliar and unexpected as well as normal, and also the interesting sequence of them, are shown.
