Abstract

sistema de determinação de propriedade de combustível para motor de combustão interna. a presente invenção refere-se a uma pressão de injeção de combustível (per) em um tempo no qual uma concentração de nox (temperatura de combustão) indica um valor máximo, sob a condição que um tempo de injeção de combustível (injt) seja fixo a um primeiro tempo de injeção (int1) e seja gravado como uma primeira pressão de injeção de pico de nox (per1). similarmente, uma segunda pressão de injeção de pico de nox (pcr2) é gravada sob a condição que o tempo de injeção de combustível (injt) seja fixo a um segundo tempo de injeção (int2). um número de cetanos (cn) e uma propriedade de destilação (t90) do combustível são determinados com base nestas pressões de injeção de pico de nox (per1 e pcr2).
