FIELD: diesel engine diagnostics during operation and inspection. SUBSTANCE: during working cycle of engine pressure sensors record moment of pressure pulse origin in space above plunger of fuel injection pump corresponding to commencement of fuel injection and moment of pressure pulse origin in fuel pump head corresponding to end of fuel injection. Cyclic fuel delivery value is determined by directly measured phase shift between mentioned time moments. EFFECT: improved accuracy of determining cyclic fuel delivery. 1 dwg
