Abstract: A retention member is configured to be supported within a cylinder head of an engine and includes a body portion and a plurality of arms. The body portion has an opening configured to receive a fuel injector of the engine. Additionally, the plurality of arms extends from the body portion and is configured to be positioned over a portion of a cross-head of the engine. The plurality of arms is spaced apart from the cross-head during routine operation of the engine.

Abstract: Methods, apparatuses, and systems for determining a dynamic shift schedule for a system are provided. A method includes: determining, by a controller, a priority for a system based on data indicative of operation of the system; determining, by the controller, a shift point for the system based on the priority and at least one of a current gear, a current accelerator pedal position (APP), an acceleration vector, or a target gear; and taking, by the controller, an action based on the determined shift point.

Abstract: A system comprises a powertrain including an engine configured to output torque to a driveline, and an electronic control system operatively coupled with the powertrain. The electronic control system is configured to determine an engine torque value, and control a component of the driveline in response to the engine torque value. The engine torque value may account for an effect of air-fuel ratio (AFR) on engine torque. The engine torque value may account for an effect of charge transport delay on engine torque

Abstract: A vehicle system includes an engine, a transmission including a torque converter, a clutch configured to selectably couple and decouple the torque converter, and a gearset, a selective catalytic reduction (SCR) exhaust aftertreatment system. An electronic control system may be operatively coupled with the engine, the electronically controllable clutch, and the SCR exhaust aftertreatment system. The electronic control system is configured to evaluate whether an SCR catalyst temperature satisfies at least one minimum temperature criterion, in response to the SCR catalyst temperature satisfying the minimum temperature criterion, permit a neutral at stop operation wherein the electronically controllable clutch is controlled to selectably decouple the torque converter and the one or more gears at least in part in response to the vehicle system being in a stopped state, and in response to the SCR catalyst temperature not satisfying the minimum temperature criterion, prevent the neutral at stop operation.
