Searching for data about the original engine is becoming a black hole for time.  What I've seen of the Benz 1886 patent just shows some detail about the car.  There are apparently a few full-scale operational copies of the car and it's engine in existence, so there must be some engineering drawings somewhere.  I'm still looking.

The original engine had a compression ratio of 2.7:1 (not much) and made about 3/4 hp at 400 rpm.
