Abstract

The present invention relates to a replaceable fluid container for an engine comprising: a first reservoir for holding a fluid; a second reservoir for holding a composition to be added to the fluid; a fluid coupling adapted to provide fluidic communication between the first reservoir and a fluid circulation system of the engine; and a dose controller to provide a dose of the composition into the fluid for circulation in a fluid circulation system of the engine.

Claims

1. A replaceable fluid container comprising:

a first reservoir for holding a fluid, wherein the first reservoir is in a housing of the replaceable fluid container;

a second reservoir for holding a composition to be added to the fluid, wherein the second reservoir is in the housing;

a dose controller to provide a dose of the composition into the fluid for circulation in the fluid circulation system of the engine, wherein the dose controller comprises a processor and a driver, wherein the driver is configured to drive opening or closing the valve based on a control signal, and wherein the dose controller is in the housing.

2. The replaceable fluid container of claim 1 wherein the dose controller comprises a communication interface for obtaining data from an operational controller associated with the engine, wherein the dose controller is configured to select at least one of a timing, dose quantity and number of doses based on the data obtained from the operational controller.

3. The replaceable fluid container of claim 2 wherein the dose controller is configured to select the at least one of the timing, dose quantity and number of doses based on a control signal received from the operational controller.

4. The replaceable fluid container of claim 2 wherein the dose controller is configured to select the at least one of the timing, dose quantity and number of doses based on at least one of the timing, dose quantity and number of doses of a previous dose.

5. The replaceable fluid container of claim 2 wherein the communication interface is arranged such that positioning the replaceable fluid container to permit fluidic communication between the first reservoir and the fluid circulation system of the engine arranges the communication interface for obtaining the data.

6. The replaceable fluid container of claim 2 wherein the dose controller is configured to inhibit the dosing of the composition into the fluid for circulation unless the communication interface is able to obtain data from the operational controller.

7. The replaceable fluid container of claim 6 wherein the dose controller is configured to select at least one property of a dose of the composition to be added into the fluid for circulation based on data obtained from the engine.

8. The replaceable fluid container claim 2 further comprising a sensor adapted to sense at least one property of a fluid of the first reservoir of the container, wherein the data obtained from the operational controller comprises data based on the sensed property of the fluid.

9. The replaceable fluid container of claim 8 in which the property of the fluid is at least one property selected from the group consisting of:

the amount of fluid, the temperature of fluid, the pressure of fluid, the viscosity of fluid, the density of fluid, the electrical resistance of fluid, the dielectric constant of fluid, the opacity of fluid, and the chemical composition of fluid.

10. The replaceable fluid container of claim 9 in which the property of the fluid is at least one property selected from the group consisting of:

the viscosity of fluid, the density of fluid, the opacity of fluid, and the chemical composition of fluid.

11. The replaceable fluid container of claim 1 comprising at least one further reservoir for holding a second composition to be added to the fluid, wherein the at least one further reservoir is in the housing, and wherein the dose controller is configured to provide a dose of the second composition from the at least one further reservoir into the fluid.

12. The replaceable fluid container of claim 11 wherein the dose controller is configured to select at least one of the timing, dose quantity and number of doses of the second composition of the at least one further reservoir based on at least one of the timing, dose quantity and number of doses of the composition of the second reservoir.

13. The replaceable fluid container of claim 11 wherein the second composition of the at least one further reservoir is different from the composition of the second reservoir.

14. The replaceable fluid container of claim 11 wherein the second composition of the at least one further reservoir is the same as the composition of the second reservoir.

15. The replaceable fluid container of claim 1 wherein the dose controller comprises a communication interface for obtaining a signal from a controller area network of the engine, and wherein the dose controller is configured to select at least one of the timing, dose quantity and number of doses based on the signal obtained from the controller area network of the engine.

16. The replaceable fluid container of claim 1 wherein the dose controller comprises a data store configured to store data describing the composition of a dose to be provided for circulation in the fluid system of the engine.

17. The replaceable fluid container of claim 16 wherein the data store is further configured to store an association between the data describing a dose and data obtained from the operational controller.

18. The replaceable fluid container of claim 17 wherein the data comprises data obtained from a controller area network of the engine.

19. The replaceable fluid container of claim 16 wherein the data store is removable with the replaceable fluid container.
