Engine Energy Science

Never mind all the fancy words. what it all boils down to is how efficiently air and fuel are converted into usable power

The conversion of chemical energy into mechanical energy is an interesting process. Typically, there is the requirement that some amount of fuel be mixed with some corresponding amount of air. Then the two [...]

More pressure on the piston, and for a longer period of time. If you had to reduce overall engine efficiency into a short sentence, it would probably include much of this thinking. And the event that creates “pressure on the piston” is related to combustion: a process of converting air and a fuel from an [...]

Originally called “mixing valves,” today’s carburetion and injection systems are still required to produce properly mixed air and fuel

In plain language, the combination of fuel with oxygen (during the conditions of combustion) is called oxidation. We could also call it, simply, combustion. But regardless of how this is accomplished, air and fuel must be combined [...]
