AB - To increase the torque and power of an engine one needs to carry out form modifications and material distribution. This has been studied through different methods and especially holography. A study of the relative mouvements in the area of the helved throws of the multi-parts crankshaft, bearing on two supports in V and submitted to a deflecting force, was obtained by measuring point by point in the real image field of a double exposure hologram. The crankshaft being positioned in a cylinder-block equipped with one cylinder and one cylinder head, the gas pressure is simulated by an oil pressure slowly increasing. Real time holograms have been performed on three different cylinder-blocks and a 16 mm film (duration 10') shows how interference fringes appear in the virtual image when the oil pressure varies. This film has permitted to the motor me chanical engineer to remedy to the cylinder-block breakings during preseries.
