Abstract
The present invention relates to an optical engine comprising a cylinder head of an industrial engine and a transparent cylinder. According to the invention, the transparent cylinder is tightly applied to the cylinder head by pneumatic means, a jack for example, allowing easy dismantling and cleaning of the cylinder. Furthermore, the industrial cylinder head is mounted on a support secured to the frame of the <<engine bottom>> by jacks or equivalent means, at least one of these means being pneumatic for opening the engine.
Claims5
An optical test engine comprising a cylinder (20) made of a transparent material, a piston (8) cooperating with said cylinder, a cylinder head (11) containing said cylinder so as to form a sealed combustion chamber, characterized in that said cylinder is applied to the plane of said cylinder head by an annular jack (17) whose travel allows access to the inside of said chamber and in that said cylinder head is secured to a frame by means of a support (12) mounted on four columns (14) consisting of guides that slide longitudinally.
