No, it had three crank throws. It's a normal 'boxer' engine, but having two crank throws and two con-rods on the outside of the first one, enabling a boxer engine with the two cylinders in line with each other.
Many years ago I read of a fanatic Citroen specialist who made special engines for 2CVs. They were flat 3 engines, with one normal cylinder and two small ones opposite, of half the piston area and having their big ends in line with each other. It was based on a similar idea to the ABC engine, eliminating the boxer twin rocking couple. I wish I could remember the name of the man making these special engines.
The ABC engine had a similar idea, but better because it used two narrow big ends and conrods to eliminate the problem without the complication of tiny cylinders. Also, there's a simpler way of dealing with it - fit a Citroen GS or Ami Super flat four engine. There have been a few Deuche built like that. There was a yellow one in 'The Spy Who Loved Me'.
