METHODS AND SYSTEMS TO CONTROL AN ENGINE OF A TRANSPORT REFRIGERATION UNIT

摘要

Systems and methods to control a prime mover of a transport refrigeration system are disclosed. A controller may be configured to receive input from various information sources including a global satellite positioning system and/or a human machine interface. The controller can be configured to select a prime mover operation mode based on the input received. In some embodiment, the controller can select a noise reduction operation mode when the TRU is located in a noise regulated area, and can select a fuel efficient mode when the TRU is located outside of the noise regulated areas. In some embodiments, the noise reduction operation mode may include increasing a speed of the prime mover in a soft sloped ramp. In some embodiments, the operation modes can include prime mover operation instructions containing parameters of fuel injection of the prime mover. The operation instructions can be sent to an ECU to execute.

主权项

1. A method to control a prime mover of a refrigerated transport unit comprising:
obtaining information from an information source; determining a prime mover operation mode based on the information obtained from the information source; obtaining a prime mover operation instruction set that is calibrated for the prime mover operation mode; and operating the prime mover according to the prime mover operation instruction set; wherein the prime mover operation mode is selected from one or more of a fuel efficient mode in which the prime mover is operated at a minimal fuel consumption level, a noise reduction mode in which the prime mover is operated at a minimal noise operation level, and an emission modulation mode in which the prime mover is operated such that at least one of a carbon dioxide emission, an oxide of nitrogen emission and a particulate matter emission is reduced.
