ANALYSER OF OPERATION OF INTERNAL COMBUSTION ENGINE SYSTEMS Russian patent published in 2014 - IPC G01M15/05 

FIELD: measurement equipment.

SUBSTANCE: invention relates to devices for measurement of parameters of internal combustion engine systems and can be used for diagnostics of internal combustion engines. An analyser includes a current detector of a starter, a pulse generator of an ignition point, a comparator, a frequency multiplier, a coincidence unit, an indicator of an average current value, an inverter, a direct-current voltmeter, an ampere-meter with a current sensor, the second, the third current sensors, an amplifier-shaper, the first and the second meters, a storage sample circuit, storage capacitors, an indicator of the state of ignition plugs and a control switch. In addition, to the device there introduced is a sine-wave oscillator, a double half-period rectifier, an amplifier cascade, a capacitor and the second voltmeter; with that, the outlet of the sine-wave oscillator is connected to the inlet of the double half-period rectifier, between the output terminals of which the amplifier cascade is connected, parallel to the output of which the capacitor and the second voltmeter is connected.

EFFECT: enlargement of the number of diagnosed engine parameters.
