A four stroke quantum engine which alternately interacts with a measurement\napparatus and a single heat bath is discussed in detail with respect to the\naverage work and heat as well as to the fluctuations of work and heat. The\nefficiency and the reliability of such an engine with a harmonic oscillator as\nworking substance are analyzed under different conditions such as different\nspeeds of the work strokes, different temperatures of the heat bath and various\nstrengths of the energy supplying measurement. For imperfect thermalization\nstrokes of finite duration also the power of the engine is analyzed. A\ncomparison with a two-temperature Otto engine is provided in the particular\ncase of adiabatic work and ideal thermalization strokes.\n
