Abstract: A powertrain system includes an engine coupled to a turbocharger and a timer, a motor generator coupled to the engine and a battery, and a controller. The controller is structured to receive data indicative of a state of charge from the battery, determine whether the state of charge is at or below a high predefined threshold, modulate control on the engine and the timer in response to determining the state of charge is above the high predefined threshold, determine whether the state of charge is above a low predefined threshold in response to the state of charge being at or below the high predefined threshold, and modulate control of the engine and the timer in response to determining the state of charge is at or below the low predefined threshold.

Abstract: An internal combustion engine system includes an engine with a plurality of pistons housed in respective ones of a plurality of cylinders, an air intake system to provide air to the plurality of cylinders through respective ones of a plurality of intake valves, an exhaust system to release exhaust gas from the plurality of cylinders through respective one of a plurality of exhaust valves. The internal combustion engine uses vacuum braking and/or compression release braking in response to one or more braking conditions.

Abstract: A system for diagnosing engine braking performance of an engine comprising a plurality of cylinders comprises an exhaust manifold pressure sensor configured to detect an exhaust manifold pressure corresponding to exhaust gas emitted from a plurality of cylinders. A controller is configured to determine an exhaust manifold pressure value corresponding to at least one cylinder of the plurality of cylinders that is being used for engine braking, from an exhaust manifold pressure sensor signal received from the exhaust manifold pressure sensor. The controller is also configured to determine an engine braking value based on the exhaust manifold pressure value.

Abstract: An intake air circuit is structured to transmit intake air from a turbocharger compressor to an intake manifold of an engine. A charge air cooler (“CAC”), a bypass line, and a bypass heater are each positioned along the intake air circuit in parallel with each other. A first control valve is structured to controllably divert the intake air around the CAC. A second control valve is structured to controllably divert the intake air around at least one of the bypass line and the bypass heater. A controller operatively coupled to each of the engine, and the first and second control valves is structured to control each of the first and second control valves to cause the intake air to flow along a determined desired flow path based on each of measured ambient temperature and measured engine load.
