METHOD OF DIAGNOSING INTERNAL COMBUSTION ENGINE Russian patent published in 2012 - IPC G01M15/04

Abstract RU 2451276 C1

FIELD: engines and pumps.

SUBSTANCE: proposed method consists in measuring strains in studs or bolts that secure cylinder head by means of transducers with strain gages arranged under nut or bolt to plot cylinder indication pressures. Plotted magnitudes are compared with reference values. Washer made from material ruling out transducer penetration on cylinder head material is fitted under transducer. Strain gages are arranged on transducer after tightening stud or bolt nut. Obtained indirect diagrams are averaged in several cycles and compared with reference and averaged reference plots.

EFFECT: higher accuracy.
