FIELD: agricultural; agricultural instrumentation engineering. ^ SUBSTANCE: according to proposed method, under operating conditions first delivery of fuel is reduced to get minimum speed of engine crankshaft. Then fuel delivery is instantaneously increase to preset value corresponding to preset speed of engine crankshaft and control rack of fuel injection pump is fixed in this position. Then acceleration of engine crankshaft is measured and rack is released. Torque is determined as product of multiplication of acceleration value by corrected moment of inertia. Power is calculated by multiplying engine torque by preset speed of engine crankshaft. ^ EFFECT: improved accuracy of determination of engine power owing to elimination of oscillations of control rack of fuel injection pump. |
