Highest engine compression ratio
Web23 de dez. de 2007 · I'm assuming you mean (regular) unleaded. That being the case I would say about 8.5:1 depending on timing. I did a bunch of research a few years back and the conclusion was that a good ballpark is to take the octane rating and directly correlate it to compression ratio. Example. 87 octane = 8.7:1, 89 octane = 8.9.1, 92 octane = 9.2:1, etc. WebThe image above shows how a jet engine would be situated in a modern military aircraft. In the basic jet engine, air enters the front intake and is compressed (we will see how later). Then the air is forced into combustion chambers where fuel is sprayed into it, and the mixture of air and fuel is ignited. Gases that form expand rapidly and are ...
