A system includes a hybrid power train comprising an internal combustion engine and electrical system, which includes a first and second electrical torque provider, and an electrical energy storage device electrically coupled to first and second electrical torque provider. The system further includes a controller structured to perform operations including determining a power surplus value of the electrical system; determining a machine power demand change value; in response to the power surplus value of the electrical system being greater than or equal to the machine power demand change value, operating an optimum cost controller to determine a power division for the engine, first electrical torque provider, and second electrical torque provider; and in response to the power surplus value of the electrical system being less than the machine power demand change value, operating a rule-based controller to determine the power division for the engine, first, and second electrical torque provider.

An apparatus remotely provides refueling management instructions for a vehicle. One or more initial vehicle parameters are determined, including an initial quantity of fuel, a plurality of route parameters including a starting point, an ending point and an estimated average fuel efficiency of the vehicle, and a plurality of refueling parameters including one or more refueling locations. The sufficiency of an initial quantity of fuel is evaluated in relation to the estimated average fuel efficiency and a distance to be traveled by the vehicle equal to a difference between the ending point and the starting point. One or more current vehicle parameters are interpreted at a first predetermined time, a refueling agenda is created, and an associated predetermined refueling amount at each of the identified one or more refueling locations is determined.

A combustion engine and a method of operating the combustion engine are disclosed. The method comprises supplying a charge gas to the combustion chamber through an intake port; discharging a cryogenic fuel in a liquid state from a fuel injector in fluid communication with the combustion chamber; closing an intake valve to close the combustion chamber; and actuating a piston during a compression cycle to compress the charge gas and the cryogenic fuel. At least a portion of the cryogenic fuel evaporates in the closed combustion chamber.

Systems, methods and techniques for exhaust gas recirculation are provided. The system includes mixing exhaust flow from at least one cylinder of an engine with air in an air intake system prior to combustion. The exhaust flow from the at least one cylinder is accumulated prior to mixing and distributed into the intake air system in a controlled manner.

Controls for improved drivability of a vehicle equipped with start/stop logic are disclosed. One exemplary embodiment is a method comprising stopping an internal combustion engine of the vehicle to achieve a target speed profile during slowing of the engine to reduce noise, vibration and harshness, and/or to achieve a target engine stop position. Another embodiment is a method for selecting between a nominal re-start mode and a delayed re-start mode where launching of the vehicle after a stop is delayed relative to the nominal start mode in response to a vehicle input.
