A mobile refrigeration system that includes an engine that is operable at a first speed greater than zero and a second speed greater than zero. A compressor is operable in response to the engine at a first speed and a second speed. The system also includes an evaporator, a first temperature sensor positioned to measure a first temperature, and a second temperature sensor positioned to measure a second temperature. A controller is operable to transition the engine between the first speed and the second speed in response to the first temperature exceeding a first predetermined value and the second temperature falling below a second predetermined value.
