Abstract

La invencion se relaciona a dispositivos mejorados que entran en contacto con levas para usarse en motores de combustion interna y de preferencia para usarse en motores de combustion interna que tienen temporizacion de valvula variable. En particular, el uso de ceramicas incluyen nitruro de silicio y carburo de silicio que han demostrado que proporcionan superficies de contacto de levas efectivas que permiten que un eje de levas que se desplaza axialmente que tenga una leva de perfil variable trabaje con mejoras resultantes en la velocidad en vacio y en la eficiencia volumetrica.
