DEVICE FOR SERVICEABILITY CHECK OF IGNITION AND FUEL EQUIPMENT ADJUSTMENT SYSTEM OF GAS-TURBINE ENGINE Russian patent published in 2004 - IPC

FIELD: electric measurement technology; measuring spark discharge parameters of spark plugs.

SUBSTANCE: device has series-connected voltage divider, signal amplitude limiter, rectifier, delay circuit, first comparator, counter, register, arithmetic multiplication unit, and display unit. Delay circuit output is also connected to inputs of second comparator and pulse repetition rate meter whose outputs are connected to inputs of AND gate and arithmetic multiplication unit, respectively. Second input of AND gate is connected to output of monostable multivibrator whose input is connected to first comparator output. AND gate output is connected to counter and register inputs. Output of fuel feed sensor is connected to counter reset input.

EFFECT: provision for adjusting fuel equipment due to measuring delay time of fuel jumping the discharge gap of spark plug.
