Abstract An internal combustion engine (30) comprising: a shaft (32); a multilobate central cam (80) fixed to the shaft (32), the central cam (80) comprising at least three lobes (83) which define a central cam surface (84); at least one cylinder module, each cylinder module comprising: a pair of cylinders, the cylinders being diametrically opposed with respect to the shaft (32) with the central cam (80) interposed therebetween; a piston (72) in each cylinder, each piston (72) comprising an associated engagement means (135) for engaging the central cam surface (84); and a connecting member (71) connecting the pistons (72), the connecting member (71) comprising an internal space (78) through which the central cam (80) extends; and wherein reciprocating motion of the pistons (72) in the cylinders in use imparts rotary motion to the shaft (32) via engagement of the engagement means (135) of the pistons (72) with the central cam surface (84) of the central cam (80). |
