Experiment-calculated estimation of derating level influence upon resource of converted B-2 type diesel engine

A physical-statistical mathematical model of consumption of recourse of converted B-2 type diesel engine is developed. Equations to define the relative speed of damage accumulation depending upon constructive and adjusting parameters, modes of application objects load are offered. Recommendations on choice of nominal values of rotation frequency and power of converted B-2 type diesel engine which provide the required life ratio are formulated.
