    Abstract: A traction loss warning system includes a warning controller configured to be disposed onboard a first vehicle and to determine a location on a route where a loss in traction of the first vehicle occurred and a vehicle controller configured to be disposed onboard a second vehicle, the vehicle controller configured to control movement of the second vehicle along the route. The warning controller also is configured to communicate a warning signal that notifies the second vehicle of the location where the loss in traction of the first vehicle occurred. The vehicle controller is configured to change the movement of second vehicle along the route during travel of the second vehicle over the location responsive to receiving the warning signal from the warning controller.

    Abstract: Fuel injector wear methodologies for use with internal combustion engines include a method that determines power of the engine and/or fuel flow of a fuel injector(s) associated with a cylinder the engine; obtains a duration of a fuel injection event from the injector(s) associated with the cylinder(s) of the engine; compares the power, the fuel flow, and/or the duration with a reference value; and then adjusts the fuel injection timing of the fuel injector(s), based on the comparison. Another method adjusts operation of an engine includes: comparing two (or more) engine models, wherein one model is related to a fuel injection event duration of the engine or a modeled fuel quantity being supplied to the engine and then adjusting the fuel injection timing of a fuel injector(s) of the engine, based on the comparison.

    Abstract: A method of controlling an engine includes injecting a first fuel and a second fuel to each of a donor cylinder group and a non-donor cylinder group of the engine. The method also includes injecting a higher fraction of the first fuel into the donor cylinder group in comparison to the first fuel being injected into the non-donor cylinder group. Further, the method includes injecting a lower fraction of the second fuel into the donor cylinder group in comparison to the second fuel being injected into the non-donor cylinder group. Furthermore, the method includes recirculating an exhaust emission from the donor cylinder group to the non-donor cylinder group and the donor cylinder group and combusting a mixture of air, the first fuel, the second fuel and the exhaust emission from the donor cylinder group in both the donor cylinder group and the non-donor cylinder group.
