How exactly does running fuel-lean increase the temperature of ignition?

처리 내용

You have a qualitative description of what happens, but let's break it down to a smaller scale. When we talk about "temperature" of something, we are really talking about how fast the molecules are moving around and bouncing off each other. "Temperature" is really "kinetic energy". And it turns out that there are other types of energy besides moving around in space -- molecules can rotate, they can vibrate, and their electrons can get excited and move around relative to the nucleus. Each of these energies can also be a "temperature", so you can have translational temperature (what we normally think of), but you can have rotational temperature, vibrational temperature, and electronic temperatures. Molecules exchange energy with one another by colliding into each other. When they do this, they also distribute the energy between them. How often they collide determines how quickly the energy becomes uniform, and this defines how quickly they reach what is called equilibrium. When all of th
