Otto's cycle

Kork

I have made an Ottos Cycle graph and found the area W_net and W₁₂. I now have to find the efficiency η = W_net/W₁₂ I have found that to be 0,20 but I have no idea what this tells me about the work or anything.

I need help.

If [itex]\eta[/itex]=.2 then the system is 20% efficient, that is, if you put some energy into the system, only 20% of that energy is converted into work, and the other 80 percent is lost as heat.
