Abstract
A hybrid drive having a load shaft; a motor/generator coupled to the load shaft; an internal combustion engine; an electromagnetic clutch, configured to disengageably couple the internal combustion engine to the load shaft, and located between the motor/generator and the internal combustion engine; and a power supply, coupled to the motor/generator and to the clutch.
Claims26
A hybrid drive comprising:
- a load shaft;
- a motor/generator coupled to the load shaft;
- an internal combustion engine;
- an electromagnetic clutch, configured to disengagably couple the internal combustion engine to the load shaft, and located between the motor/generator and the internal combustion engine;
- and
- a power supply, coupled to the motor/generator and to the clutch.

A hybrid drive comprising:
- a load shaft;
- a electric motor, coupled to the load shaft;
- an over-running one-way clutch, coupled to the load shaft;
- a motor/generator, disengageably coupled to the load shaft through the over-running one-way clutch;
- an internal combustion engine, coupled to the load shaft and the electric motor, so that the load shaft is driven by a source selected from the group consisting of the electric motor, the internal combustion engine in combination with the motor/generator, and the internal combustion engine in combination with the motor/generator and the electric motor;
- and
- a power supply, coupled to the electric motor and the motor/generator.
An improved fuel vaporizer, of the type coupled for use with an internal combustion engine, and including a body, a fuel inlet, an air inlet, an air/fuel outlet, and a heater that vaporizes the fuel, wherein the improvement is characterized in that the air inlet is disposed in a direction tangential to fuel flow so as to cause formation of an air vortex that mixes with fuel from the fuel inlet.
