A system for controlling engine vibration, noise, and temperature in a cab of a vehicle including a crankshaft rotated by and extending from an engine, the system comprising:
- a flywheel generator system operatively mounted on the engine, the flywheel generator system being configured to actively dampen crankshaft vibrations and to generate electricity;
- and
- a temperature control unit electrically coupled to the flywheel generator system, the temperature control unit being configured to control the temperature in the vehicle cab.
A system for controlling engine noise and temperature in a cab of a vehicle including a crankshaft rotatably connected to and driven by the engine, the system comprising:
- a temperature control unit configured to control the temperature in the cab of the vehicle;
- a power converter electrically connected to the temperature control unit to provide operating power to the temperature control unit;
- and
- a generator configured to generate power and supply the power to the power converter, the generator being operatively mounted on the crankshaft and configured to actively dampen vibrations of the crankshaft.
A vehicle including a cab for a vehicle operator, the vehicle comprising:
- a diesel powered, internal combustion engine;
- a crankshaft driveably rotated by the engine and extending from the engine;
- an HVAC system configured to control the temperature in the cab of the vehicle;
- a power converter electrically connected to the HVAC system to provide operating power to the HVAC system;
- and
- a generator configured to generate power and supply the power to the power converter, the generator being operatively mounted on the crankshaft and configured to actively dampen vibrations of the crankshaft.
