Abstract

método e dispositivo para controle funcional de uma bomba de combustível de alta pressão é realizado um método para controle da função de uma bomba de alta pressão (5) de um sistema para injeção de combustível de um motor de combustão, durante condições operacionais estacionárias do motor de combustão, com um valor de referência constantemente solicitado para a pressão de combustível em um tanque acumulador (6). assim, uma bomba de alimentação (2), de uma parte de baixa pressão (3) do sistema, é controlada de modo que a pressão de combustível na parte de baixa pressão, na entrada para a bomba de alta pressão, caia e, ao mesmo tempo, esta pressão de combustível seja medida, bem como a pressão de combustível no tanque acumulador. o desenvolvimento da pressão de combustível medida no tanque acumulador é comparado com dito valor de referência durante a redução da pressão na parte de baixa pressão, para geração de informação acerca da funcionalidade da bomba de alta pressão.
