Abstract

One example aspect of the present disclosure is directed to a method for measuring engine performance. The method includes receiving a plurality of parameters related to engine performance. The method includes receiving an indication of an engine wash event. The method includes determining an effectiveness of the engine wash event based on the plurality of parameters. The method includes performing a comparison of the effectiveness of the engine wash event with an expected effectiveness of the engine wash event. The method includes performing a control action based on the comparison.

First claim

What is claimed is:

1 . A system comprising:
one or more memory devices; and one or more processors configured to:
receive a plurality of parameters related to engine performance;
receive an indication of an engine wash event;
determine an effectiveness of the engine wash event based on the plurality of parameters;
perform a comparison of the effectiveness of the engine wash event with an expected effectiveness of the engine wash event; and
perform a control action based on the comparison.

2 . The system of claim 1 , wherein the control action comprises scheduling a new engine wash event based on the comparison.

3 . The system of claim 1 , wherein the control action comprises scheduling a service based on the comparison.

4 . The system of claim 1 , wherein the control action comprises scheduling a maintenance action based on the comparison.

5 . The system of claim 1 , wherein the one or more processors are further configured to:
receive a second plurality of parameters related to engine performance; receive an indication of a second engine wash event; determine an effectiveness of the second engine wash event based on the second plurality of parameters; and perform a second comparison, wherein the second comparison is a comparison of the effectiveness of the second engine wash event with an expected effectiveness of the second engine wash event.

6 . The system of claim 5 , wherein the expected effectiveness of the first engine wash event is the same as and the expected effectiveness of the second engine wash event.

7 . The system of claim 5 , wherein the expected effectiveness of the second engine wash event is influenced by at least the expected effectiveness of the first engine wash event and the effectiveness of the first engine wash event.

8 . The system of claim 5 , wherein the one or more processors are further configured to model the effectiveness of engine wash events based, at least in part, on the effectiveness of the first engine wash event and the effectiveness of the second engine wash event.

9 . The system of claim 5 , wherein the one or more processors are further configured to create a model of the effectiveness of engine wash events based, at least in part, on the effectiveness of the first engine wash event.

10 . The system of claim 9 , wherein the one or more processors are further configured to revise the model based, at least in part, on the effectiveness of the second engine wash event.

11 . The system of claim 10 , wherein the one or more processors are further configured to:
predict a need for a third engine wash event based on the model; and notify a user of the need.

12 . The system of claim 1 , wherein receiving an indication of an engine wash event further comprises receiving one or more engine wash event attributes.

13 . The system of claim 12 , wherein determining an effectiveness of the engine wash event further comprises categorizing the engine wash event into at least one category based, at least in part, on the received one or more engine wash event attributes.

14 . The system of claim 12 , wherein the one or more engine wash event attributes comprises one or more of the following: a wash date, a wash time, a wash station, a washer, a washer skill level, a worker experience level, a worker training level, a number of washers, an engine, a fleet, a number of wash cycles, a total dissolved solvents measurement at each cycle, a total suspended solvents measurement at each cycle, a number of rinses, a total dissolved solids, or an equipment type.

15 . A method for measuring engine performance comprising:
receiving, by one or more computing devices, a plurality of parameters related to engine performance; receiving, by the one or more computing devices, an indication of an engine wash event; determining, by the one or more computing devices, an effectiveness of the engine wash event based on the plurality of parameters; performing, by the one or more computing devices, a comparison of the effectiveness of the engine wash event with an expected effectiveness of the engine wash event; and performing, by the one or more computing devices, a control action based on the comparison.

16 . The method of claim 15 , wherein the control action comprises scheduling, by the one or more computing devices, a new engine wash event based on the comparison.

17 . The method of claim 15 , wherein the control action comprises scheduling, by the one or more computing devices, a service based on the comparison.

18 . The method of claim 15 , wherein the control action comprises scheduling, by the one or more computing devices, a maintenance action based on the comparison.

19 . The method of claim 15 , further comprising:
receiving, by the one or more computing devices, a second plurality of parameters related to engine performance; receiving, by the one or more computing devices, an indication of a second engine wash event; determining, by the one or more computing devices, an effectiveness of the second engine wash event based on the second plurality of parameters; and performing, by the one or more computing devices, a second comparison, wherein the second comparison is a comparison of the effectiveness of the second engine wash event with an expected effectiveness of the second engine wash event.

20 . An aerial vehicle comprising:
one or more memory devices; and one or more processors configured to:
receive a plurality of parameters related to engine performance;
receive an indication of an engine wash event;
determine an effectiveness of the engine wash event based on the plurality of parameters;
perform a comparison of the effectiveness of the engine wash event with an expected effectiveness of the engine wash event; and
perform a control action based on the comparison.
