Abstract: A piston for an opposed-piston engine has a thermal barrier coating on at least the piston crown. The piston, at least the piston crown, is made of titanium or a titanium alloy. The thermal barrier coating includes a bonding material and a ceramic material. The bonding material can be present in the thermal barrier coating at an interface of the thermal barrier coating and the bulk of the piston material. The ceramic material can be a high R-Value material. In particular, the piston with a thermal barrier coating can be an exhaust piston for an opposed-piston engine.

Abstract: An apparatus includes a control circuit. The control circuit is structured to interpret condition data indicative of an external operating condition of a vehicle, determine an operating parameter of the vehicle based on an actuator response of an actuator of the vehicle, compare the operating parameter to an operating parameter threshold where the operating parameter threshold is based on the external operating condition, and remap an actuator response map of the actuator based on the comparison indicating that the operating parameter does not satisfy the operating parameter threshold. The operating parameter includes at least one of a fuel economy value, an emissions value, an acceleration value, a braking value, or a wear value.

Abstract: A computing system is disposed remote from a vehicle and communicably coupled to the vehicle over a network. The computing system includes a communications interface, one or more processors, and memory storing instructions that when executed by the one or more processors, cause the one or more processors to receive a first emissions data packet from a vehicle controller, the first emissions data packet including a plurality of emissions values regarding operation of a vehicle; determine whether a first cumulative emissions value is greater than a threshold value; and responsive to determining that the first cumulative emissions value is greater than the threshold, performing, by the remote computing system, corrective operations.

Abstract: System, apparatus, and methods are disclosed for identifying passing opportunities for a vehicle and controlling the vehicle in response to the passing opportunities. For example, operation of one or more components of the vehicle can be changed in advance of attempting the pass to better prepare the vehicle for acceleration to initiate and complete the pass attempt. Operation of one or more components of the vehicle can be changed during passing to assist the vehicle in completing the pass.

Abstract: In some implementations, a method may include obtaining target fault data indicating a preselected fault for a vehicle having a hydrogen source. In addition, the method may include obtaining vehicle fault data indicating a fault of the vehicle. The method may include identifying a match between the fault and the preselected fault. Moreover, the method may include purging, in response to the identifying the match, hydrogen from the hydrogen source so as to reduce consequences of a battery thermal event by reducing the likelihood of a hydrogen-fueled fire.

Abstract: A method for delaying cylinder reactivation in a vehicle includes identifying, by a controller, a request to exit a cylinder deactivation state. The controller determines if the request is due to a transient condition. If the request is due to the transient condition, the controller analyzes at least one of the transient condition and a condition of the vehicle. The controller determines a first adjustment to the vehicle based on analyzing at least one of the transient condition and the condition of the vehicle. The first adjustment is configured to mitigate the transient condition. The controller implements the first adjustment.

Abstract: A method includes operating a spark ignition engine and flowing low pressure exhaust gas recirculation (EGR) from an exhaust to an inlet of the spark ignition engine. The method includes interpreting a parameter affecting an operation of the spark ignition engine, and determining a knock index value in response to the parameter. The method further includes reducing a likelihood of engine knock in response to the knock index value exceeding a knock threshold value.
