Abstract
Se proporciona un inyector unitario diesel del tipo EMD, con una punta cuyo radio está centrado por debajo del centro del radio del saco que circunscribe, y el volumen del saco es minimizado. La cara inferior del cuerpo de la boquilla del inyector es rectificada, de manera tal que mantenga una fuerte seccion transversal de pared. Un sistema que utiliza un conjunto de asientos de resorte substitutos potenciales, se emplea para reajustar la presion de abertura, tal como al reconstruir, dentro de tolerancias estrechas. El cuerpo de boquilla está recortado y la jaula de válvula de retencion de manera correspondiente se alarga para reducir la longitud de la propia válvula de inyeccion. Se reduce el volumen atrapado consistentemente con los requerimientos de flujo de combustible.
