One billionth of one and one third of micro ,to be precise 10-9m. Nanotechnology is the manipulation of matter on an atomic and molecular scale. Nano technology in mechanical field is the internal combustion engine on a nano scale.The Nano is a A0.1cc compression ignition engine - most frequently, if somewhat inaccurately, referred to as a "diesel". It was designed by Richard Gordon and the plans were included as a supplement with the British Magazine Model Engineer in the early 1990's.
When it is fired, it run briefly, oscillating back and forth about TDC like over compressed diesels with small mass fly wheels But spring starters are the only way to start ultra small diesels , hand propping just won't work.
