Abstract
The electric energy generated by an electric generator driven by an engine on a motor vehicle is stored in a large-capacity capacitor when the rotational speed of the engine increases while the engine is idling, thereby imposing a load on the engine. At this time, the increase in the rotational speed of the engine is suppressed. The electric energy stored in the capacitor is supplied to a battery on the motor vehicle, charging the battery.
Claims3
An apparatus for reducing the vibration of an engine mounted on a motor vehicle while the engine is idling, comprising:
- an electric generator drivable by the engine;
- capacitor means adapted to be mounted on the motor vehicle, for storing electric energy;
- a battery adapted to be mounted on the motor vehicle;
- detecting means for detecting a variation in the rotational speed of the engine;
- capacitor charging control means for charging said capacitor means with electric energy generated by said electric generator when the rotational speed of the engine varies as detected by said detecting means;
- and
- battery charging control means for charging said battery with the electric energy stored in said capacitor means.
