METHOD AND SYSTEM FOR PREDICTIVE EMISSION MAINTENANCE OF AN ENGINE

摘要

Methods and systems for predictive emission maintenance of an engine. In one embodiment, a method for predictive emission maintenance of an engine is provided. The method can include a controller obtaining operational status information of the engine upon startup of a transport refrigeration unit (TRU) or a TRU generator set (GenSet). The method also includes the controller predicting engine emission maintenance based on the operational status information. Also, the method includes the controller providing an advanced notification warning based on whether the controller predicts engine emission maintenance.

1. A method for predictive emission maintenance of a common rail diesel engine having an emissions reduction system that includes an exhaust gas recirculation (EGR) valve component, the method comprising:
a controller obtaining an initial valve position of a valve of the EGR valve component with respect to a seat of the EGR valve component upon startup of a transport refrigeration unit (TRU) or a TRU generator set (GenSet); the controller predicting engine emission maintenance based on the initial valve position of the valve of the EGR valve component; the controller providing an advanced notification warning based on whether the controller predicts engine emission maintenance.
