<p>An exhaust gas-driven turbine (12) drives a compressor (14) to charge an internal combustion engine. An integral motor (56) is positioned on the turbocharging shaft (16) to add power to the turbocharging shaft (16), especially at low exhaust gas volume. Cooling for this motor (56) includes circulation of engine oil therearound and may include insulation to limit heat inflow from the turbine (12) and may include air flow through the motor (56) to carry away heat inflow from the turbine (12).</p> |
