Abstract

alternativa de ângulo de ignição antes da posição de ponto morto superior (tdc). a presente invenção se refere a métodos e dispositivos para regular a velocidade de um motor de combustão de dois tempos. assim, é provida uma disposição para alternar uma regulagem de ignição relativa a uma posição de ponto morto superior. para uma dada velocidade de motor, a regulagem de ignição pode ser ajustável de maneira escalonada. uma ou mais etapas podem ser usadas enquanto se alterna entre duas regulagens de ignição. a regulagem de ignição pode ser ajustada quando a velocidade do motor aumenta acima de uma velocidade limite do motor.
