Abstract
Perfeccionamientos introducidos en motores diesel, de cuatro tiempos y de dos válvulas por cilindro, cada uno de cuyos inyectores está alojado en la culata en forma tal que proyecta, al menos, tres chorros de carburante en la dirección de una cámara de combustión, integrada a la cabeza del pistón correspondiente, caracterizado porque la excentricidad de cada inyector en su cilindro es, al menos, igual a cero con quince veces el diámetro de calibrado del citado cilindro, mientras que la altura de la cámara de combustión integrada a la cabeza de cada pistón es, como máximo, igual a cero con cincuenta y cinco veces el diámetro máximo de la citada cámara; estando la excentricidad del inyector definida como la longitud que separa al punto de intersección del eje de simetría del cilindro con el plano que contiene la cara inferior plana de la culata, con respecto al punto de intersección del eje de simetría del inyector con este mismo plano; estando la altura de la cámara definida como la mayor profundidad de la cámara, medida paralelamente al eje de simetría del cilindro; y siendo el diámetro máximo de la cámara igual al mayor de los diámetros medidos paralelamente a la cara inferior de la culata.
