The original Atkinson-cycle piston engine allows the intake, compression, power, and exhaust strokes of the four-stroke cycle to occur in a single turn of the crankshaft and was designed to bypass patents covering the existing Otto cycle engines.[1] Due to the unique crankshaft design of the Atkinson, the expansion ratio may differ from the compression ratio. By adjusting the linkage to allow a power stroke that is longer than the compression stroke, the engine can achieve greater efficiency than with the Otto cycle engine. While Atkinson’s original engine design is no more than a historical curiosity, the Atkinson cycle, where the power stroke is longer than the compression stroke, is increasing in popularity due to the increase in fuel economy it provides.
Figure:
The ideal Atkinson cycle consists of following operations:
1) Isentropic or reversible adiabatic compression (that is, compression with no transfer of heat).
2) Addition of heat at constant volume.
3) Isentropic expansion.
4) Rejection of heat at constant pressure.

I thought this had something to do with carbs.
Derp.
your post, it makes very little sense…I could click the link and find out, but i’m no very interested. Still runs on gas huh.
wut?
I was told there was no math….
I don’t understand.
huh?? o_O
What is with the shit quality of this post?
Its thermodynamics, its not worth the time it would take to learn, and its worth the time it takes to forget it.
There is always math. Always.
Not “Math”, its “Thermodynamics”!!!!!!!!!!
