I have this thermodynamics question.

Keep in mind I could honestly not care less about engines. It's not exactly pertinent toward my major.

I calculated the kW an engine produces per cycle. The engine is running at 1600 RPM. I converted that to RPS, and multiplied that by the number of cylinders.

W (total) = W (per cycle) * RPS * cylinders

This doesn't get me close to the answer. It's about one fourth. This is a four stroke engine. Wouldn't a 4 stroke engine only make power once every two revolutions?

Or am I thinking backwards?
