Abstract
a presente invenção se refere a um método para determinar a constante de gás específica e a razão estequiométrica entre ar e combustível de um gás combustível para um motor a gás. o método compreende a etapa de manter a pressão essencialmente constante em uma tubulação de admissão do motor a gás, de modo que a pressão não varie mais que um limite predeterminado. um primeiro valor ¿ é determinado a jusante do motor a gás. o período de tempo de injeção de gás na tubulação de admissão é, então, alterado. um segundo valor ¿ a jusante do motor a gás é determinado após a alteração do período de tempo de injeção de gás na tubulação de admissão. a constante de gás específica e a razão estequiométrica entre ar e combustível do gás combustível são, então, determinadas com base no primeiro e no segundo valores ¿ determinados. a presente invenção também se refere a um sistema para determinar a constante de gás específica e a razão estequiométrica entre ar e combustível de um gás combustível para um motor a gás, um veículo, um programa de computador e um produto de programa de computador.
