“Nicholas-Joseph Cugnot became the first automobile engineer when his steam powered Fardier (wheeled cart) became the first self-propelled vehicle. He had to design and build the first steam engine, where steam, at a higher pressure than atmospheric pressure, droimageve a piston in a cylinder. He also invented a rotary valve activated by the piston to let the steam in and out of the machine’s two cylinders. The vehicle was demonstrated in France in 1770, pulling a five-ton artillery cannon.
