Method and system for predictive emission maintenance of an engine
First Claim
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 a notification based on the predicted engine emission maintenance.

Abstract
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.

10. An emission reduction system for a common rail diesel engine comprising:
-
an exhaust gas recirculation (EGR) valve component reducing emissions of the common rail diesel engine, the EGR valve component including a valve and a seat; a sensor configured to monitor an initial valve position of the valve of the EGR valve component with respect to the seat of the EGR valve component upon startup of a transport refrigeration unit (TRU) or a TRU generator set (GenSet); and a controller programmed to receive the initial valve position, programmed to predict engine emission maintenance based on the initial valve position, and programmed to generate and provide a notification to a user based on the predicted engine emission maintenance. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)
