An engine system that delivers torque to a driveline of a vehicle includes an internal combustion engine (ICE), a manifold, an exhaust gas recirculation (EGR) circuit, an electric turbine (eTurbine) and a controller. The EGR circuit has an EGR valve that selectively moves between open and closed positions. The eTurbine is driven by an electric motor and is configured to deliver air away from the manifold. The controller determines an ICE start request and, based on the ICE start request, sends a signal to the EGR valve to open thereby fluidly connecting the manifold and the eTurbine. The controller sends a signal to the eTurbine to rotate and move air out of the manifold through the EGR circuit. The eTurbine is used to deplete air in the manifold before starting the ICE. As a result, a reduction in fuel used and therefore a reduction in emissions at startup is achieved.

Electronic turbine and engine exhaust gas recirculation for reduction of cold start emissions and noise vibration and harshness

An engine system that delivers torque to a driveline of a vehicle includes an internal combustion engine (ICE), a manifold, a compressor and a controller. The manifold selectively communicates air into the ICE. The compressor 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, based on the ICE start request, sends a signal to the electric motor to rotate the compressor in a direction that moves air out of the manifold. The eCompressor is used to deplete air in the manifold before starting the ICE. As a result, a reduction in fuel used and therefore a reduction in emissions at startup is achieved.

Electronic compressor for reduction of cold start emission and noise vibration and harshness

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.
