The efficiency of energy transformation of overdamped Brownian particles in a tilted periodic sawtooth potential driven by a nonequilibrium three‐level noise and an additive thermal noise is considered analytically. All the physical results are computed by means of exact formulas. It is established that in certain parameter region the dependence of the efficiency of energy transformation on noise parameters exhibits a bell‐shaped form. Thus, in such parameters regions an increase of values of noise characteristics (temperature, noise flatness, correlation time, and noise amplitude) can facilitate conversion of noise energy into mechanical work. A connection such as resonance‐like behavior of efficiency at multiple current reversals is also discussed.
