Abstract

La válvula de émbolo alargado, junto con el sistema de levas conjugadas, es mecánicamente diferente al antiguo sistema de distribución.#La cabeza de la válvula de émbolo alargado en su retroceso por el cilindro de escape facilita el paso de los gases y a la vez hace de pantalla protectora de la pared en la que el segmento rascador ya antes ha retirado al desagüe la película de aceite, mientras las cabezas de la válvulas de émbolo alargado están en el tiempos de compresión y expansión, en su interior hay una gran renovación de aceite que las refrigera.#La leva cóncava el rodillo y la leva convexa, los tres siempre están en contacto y cuando el rodillo pasa por los perfiles circunferenciales de las válvulas de émbolo alargado indica que están cerradas, ya que el émbolo del motor está realizando seguidos los tiempos de compresión ignición y expansión.The elongated piston valve, together with the conjugate cam system, is mechanically different from the old distribution system. # The head of the elongated piston valve in its retraction by the exhaust cylinder facilitates the passage of gases and at the same time makes of protective screen of the wall in which the scraper segment has previously removed the oil film to the drain, while the heads of the elongated piston valves are in the times of compression and expansion, inside there is a great oil renewal that cools them. # The cam concave the roller and the convex cam, the three are always in contact and when the roller passes through the circumferential profiles of the elongated piston valves indicates that they are closed, since the engine piston is performing in a row Compression times ignition and expansion.
