Abstract: Starting an internal combustion engine may be difficult as a consequence of the operating conditions of the engine. Even after the engine has started, it may take a long period of time for the engine to reach operating temperatures. In the present disclosure, when engine start difficulty is expected, before starting the engine a forced induction compressor arranged with the engine may be turned on to increase the engine intake air pressure before the engine is started.

Abstract: Starting an internal combustion engine may be difficult as a consequence of the operating conditions of the engine. Even after the engine has started, it may take a long period of time for the engine to reach operating temperatures. In the present disclosure, starting difficulty is expected for an engine with an exhaust gas recirculation system, before starting the engine an exhaust gas aftertreatment device is heated to warm residual air within the exhaust gas system.

Abstract: A turbocharger system comprises: a turbocharger having a rotatable shaft arranged to be driven by exhaust gases from an associated engine and coupled to a turbocharger electrical machine; and a controller configured to switch the turbocharger electrical machine between a first mode in which electrical energy is drawn from the turbocharger electrical machine acting as a generator and a second mode in which energy is provided to the turbocharger electrical machine to act as a motor. The controller may be configured to switch between the first mode and the second mode based upon the power factor for the electrical energy generated by or supplied to at least one of: the turbocharger electrical machine; and an engine electrical machine coupled to the associated engine.

Abstract: A Gen-Set (10) control system is disclosed. The control system has an engine (12) having a desired operating range and a generator (14) driven by the engine to produce an electrical power output. The control system also has an engine control module (30) communicatively coupled with the engine, and configured to change and operating parameter of the engine based on a load command before a load on the engine causes the engine to deviate from the desired operating range. The control system further has an automatic voltage regulator (32). The automatic voltage regulator is configured to monitor at least one of a voltage output, a current output, and a power factor of the generator and generate the load command based on a change in at least one of the voltage output, the current output, and the power factor. The automatic voltage regulator (32) is also configured to deliver the load command to the engine control module (30).
