In this paper is presented the calculus, designed by the authors, of the fuel supply scheme for a multipoint injection system. The calculated outputs are the fuel consumption and the injection duration depending on the rotational speed and on the environmental temperature. A a computer program was developed to determine the parameters of an SI engine in two cases: 1. the calculation of the injection parameters depending on the rotational speed (n) and on the air fuel ratio () for environmental temperatures t0=-35...+45 0C and environmental pressures p0=1·105 Pa; 2. the calculation of the injection parameters depending on the rotational speed (n) and on the environmental temperature t0 for an air-fuel ratio =1 and environmental pressures p0=1·105 Pa.
