Automatic Shut-down/ Start-Up Systems (AESS)
An automatic engine shut-down/start-up system not only turns off the locomotive main engine while idling but can re-start the engine when necessary. Re-start of the main engine is typically based on a set time period, engine or ambient temperature, and other parameters (e.g., battery charge). SmartWay has only verified AESS systems for locomotives. Systems generally incorporate technologies that continuously monitor existing conditions against a preprogrammed set of values. These systems monitor the following operating conditions: reverser and throttle position, air brake cylinder pressure, engine coolant and ambient air temperature, battery voltage and charging amperage.
SmartWay has verified technologies among the product lines of the following company:
