118: 127: 85: 109: 96:, which replaced clumsy gear shifting with a smooth, highly efficient, continuously variable transmission. The transmission ratio was determined by the oscillation of a pendulum, the extent of the oscillations being determined by the pendulum's mass, ingenious attachment, and dimensions in combination with the torque and speed of the engine and the road wheels. An oscillating masses torque converter was used to eliminate the need for a complex geared automotive transmissions which were heavy, required shifting gears, and could be inefficient. Compared to a similar car with a gear based transmission, Constantinesco's needed a substantially smaller engine, was lighter overall, and was more fuel efficient. In the car, the mechanical torque converter was embodied in a 494 cc twin-cylinder 31: 162:
signed a "lucrative" royalty agreement to manufacture the torque converters, giving Constantinesco a $ 100,000 advance on royalties, but didn't make any, leaving the inventor deeply in debt and the mechanical torque converter sidelined.
