Abstract

a presente invenção refere-se a um procedimento para minimizar nox durante variações de cargas de motores em um motor a diesel de 4 tempos compreendendo pelo menos um cilindro com uma cabeça de cilindro (1), um primeiro pistão alternativo (2) montado em uma haste de conexão (3) um atuador (4) montado na cabeça do cilindro e um do segundo pistão acionado pelo atuador (5) que pode ser travado através de um circuito hidráulico (6) em várias posições em uma câmara de combustão (7), pelo menos um dos cilindros pode direcionar válvulas de saída existentes (8) para evacuação de gases de escape, pelo menos uma na cabeça de cilindros existente (10) para o fornecimento de ar de combustão, pelo menos um para a câmara de combustão (7) ligada ao injetor (9) para injeção de combustível na referida câmara. o procedimento é caracterizado pelo segundo pistão (5), o mais tardar durante o curso de compressão atual, ser acionado pelo atuador (4) e ser travado pelo circuito hidráulico (6) em uma posição na câmara de combustão (7), onde pelo primeiro pistão (2) o ar introduzido é comprimido em uma taxa de compressão predeterminada para atender a uma carga de motor existente onde a válvula de entrada operada livremente (10) é levada para fechar o curso de entrada em uma posição de pistão onde o volume da combustão do ar introduzido no final do curso de compressão dá a taxa de compressão predeterminada e que o injetor (9) injeta a quantidade declarada de combustível.
