In this question, we look at a gasoline engine, right? so it's a gasoline, gasoline engine.
00:10
So this gasoline engine has compression ratio, compression ratio, right? equals six, and use a gas for which gamma, which is the adibatic constant, of course, 1 .4, right? so you asked what is the efficient engine if it operates in adelast auto -soaker? well, the answer is, the calculation is very simple.
00:39
Let me just go through it.
00:41
So the efficiency of a, i'll call it eo of the art circle, is simply given by 1 minus 1 over v1 over v2 gamma minus 1.
00:53
All right.
00:55
Now, the compression, the compression ratio is 6.
01:01
So that means v1 over v2 is 6...
