Abstract: An engine system that delivers torque to a driveline of a vehicle includes an internal combustion engine (ICE), a manifold, an engine phaser (ePhaser), an electric turbine (eTurbine) and a controller. The ICE includes intake valves and exhaust valves. The ePhaser is configured to adjust timing of the intake and exhaust valves. The eTurbine is driven by an electric motor and is configured to deliver air toward and away from the manifold. The controller determines an ICE start request and, sends a signal to the ePhaser to open identified valves of the intake valves and the exhaust valves creating a pathway through the ICE. The controller further sends a signal to the electric motor to rotate the eTurbine in a direction that moves air out of the manifold. The eTurbine is used to deplete air in the manifold before starting the ICE and reduce emissions at startup.

Abstract: An exhaust system for a vehicle having an internal combustion engine includes an exhaust pipe having a central axis and configured to receive an exhaust gas flow from the engine, a catalytic converter disposed within the exhaust pipe, and an exhaust gas burner assembly having a burner unit configured to generate and supply a heated burner flow to a supply pipe. An outlet end of the supply pipe is disposed within the exhaust pipe and extends substantially parallel to the exhaust pipe central axis such that the exhaust gas flows around the supply pipe outlet end. A plurality of mixing apertures are formed in the supply pipe outlet end and configured to promote mixing of the heated burner flow and the exhaust gas flow to disperse heat over the catalytic converter for rapid heating thereof.

Abstract: Electrified powertrain control techniques include, in response to a detected cold start request for an engine, controlling one or more electric motors to generate drive torque to physically power an engine for a period to increase a temperature within a primary combustion chamber of a cylinder of the engine, and after the period, starting the engine by combusting a primary charge of fuel/air within the primary combustion chamber using a turbulent jet ignition (TJI) system to combust a pre-charge of fuel/air in a respective pre-chamber of the cylinder using a respective first spark plug and expelling heat energy therefrom into the primary combustion chamber of the cylinder, thereby eliminating a need for a respective second park plug of the TJI system that is associated with the cylinder and configured to heat and promote combustion within the primary combustion chamber.
