The Trojan engine had a pair of cylinders connected at the blind end with the pistons on a V-shaped con-rod. It is that con-rod that has to bend each rev. to accommodate the geometry.
Jowett's use of horizontally-opposed engines included a Vintage flat-twin sidevalve, last seen in the Bradford vans, but the flat-four o.h.v. Javelin and Jupiter engine was not used in the commercials.
