Title: (EN) Arrangement in a two cycle combustion engine with internal combustion
Abstract: front page image
(EN) A combustion engine (10) has a number of engine cylinders (21-1 - 21-5) arranged in an annular series around a common middle drive shaft (11) with the cylinder axes running parallel to the drive shaft. Each cylinder includes a pair of pistons (44, 45) movable towards and away from each other, which work in a common, intermediate working chamber (K). Each piston (44, 45) forms - via a piston rod (48, 49) with associated support roll (53) - support and control via a 'sine' - plane ('sine' - curve (8a, 8b)) in a cam guide device. The two pistons (44, 45) in each cylinder (21; 21-1 - 21-5) have mutually differing piston phases, which are controlled by mutually differing cam guide devices. The cam guide devices are designed with equivalent mutually differing 'sine' - planes ('sine' - curves (8a, 8b)).
