Abstract
Perfeccionamientos en motores de combustión interna de dos tiempos regulados por lumbreras, caracterizados porque éstos tienen una cámara o espacio de combustión limitado en el interior del cilindro, entre una culata de éste y la cara superior de un pistón de movimiento alternativo en el cilindro, y en la pared de éste existe por lo menos una lubrera de escape y como mínimo una lumbrera principal de entrada para el aire de barrido; estas lumbreras están dispuestos de tal modo que empiezan a descubrirse primero por el pistón y a abrirse al espacio de combustión durante la última parte de la carrera de combustión durante la última parte de la carrera de combustión realizada por el pistón y la lumbrera principal de entrada se alimenta con aire de barrido a presión y se dispone además en la pared del cilindro, por los menos una lubrera adicional de entrada más alejada del cabezal del cilindro que la lumbrera de entrada principal y, por tanto, empieza a descubrirse primero por el pistón y a abrirse al espacio de combustión en un momento correspondientemente posterior, durante la carrera de combustión; la lubrera adicional de entrada se alimenta también con aire sometido a presión.
