Abstract

The engine consists of a gearbox (1) and four crankshafts (3) connected to the main drive shaft (5) through bevel gears, and an auxiliary shaft (7) in line with the drive shaft. The bevel gears (11, 12) drive the camshafts, and the cylinder block (13) is adjacent to the gearbox. The cylinder heads (16) are separate for each cylinder. The ignition circuit is mounted on a plate (19) and driven by the auxiliary shaft at engine speed. The cam shaft and auxiliary shaft are driven at engine speed.
