Abstract
La presente pretende reducir un desequilibrio giratorio de un árbol de levas que está causado por un sistema de descompresión y también perfeccionar la exactitud en la apertura y cierre de una válvula del motor efectuada por una válvula accionada por leva. Un motor de combustión interna incluye un sistema de descompresión que incluye un peso centrífugo y una leva de descompresión. El peso centrífugo está soportado de manera oscilante en un árbol de levas de un sistema de válvulas. La leva de descompresión está accionada por el peso centrífugo oscilante. La leva de descompresión ocupa una posición de descompresión donde la leva de descompresión abre la válvula del motor durante el tiempo de descompresión para que la presión en un espacio de combustión quede reducida en el momento de la puesta en marcha del motor cuando el peso centrífugo está posicionado del lado de la velocidad baja. La leva de descompresión ocupa una posición de liberación de descompresión donde la leva de descompresión no abre la válvula del motor después de la puesta en marcha del motor cuando el peso centrífugo se encuentra en la posición del lado de la velocidad alta. Un peso de equilibrado está provisto en el árbol de levas. El peso de equilibrado reduce un desequilibrio del árbol de levas que está causado por el peso centrífugo en la posición del lado de la velocidad alta. El peso de equilibrado incluye una pluralidad de partes del peso que están espaciadas, una de la otra, en la dirección axial del árbol de levas.This is intended to reduce a rotating imbalance of a camshaft that is caused by a decompression system and also to improve the accuracy in the opening and closing of a motor valve made by a cam-operated valve. An internal combustion engine includes a decompression system that includes a centrifugal weight and a decompression cam. The centrifugal weight is oscillatingly supported on a camshaft of a valve system. The decompression cam is driven by the oscillating centrifugal weight. The decompression cam occupies a decompression position where the decompression cam opens the engine valve during the decompression time so that the pressure in a combustion space is reduced at the time of starting the engine when the centrifugal weight is positioned on the low speed side. The decompression cam occupies a decompression release position where the decompression cam does not open the engine valve after engine start-up when the centrifugal weight is in the high speed side position. A balancing weight is provided on the camshaft. The balancing weight reduces an imbalance of the camshaft that is caused by the centrifugal weight in the high speed side position. The balancing weight includes a plurality of parts of the weight that are spaced, one from the other, in the axial direction of the camshaft.
