The bolometric light curve of the peculiar type I supernova (SN I) SN 1983n and of the normal SN I SN 1972e have been calculated. The optical depth of the envelope for gamma-quanta in the case of SN 1983n is shown to be approximately 2.6 times larger than in the case of SN 1972e. The restrictions on the values of the mass and expansion velocity of the envelope of a peculiar SN I relative to the values for a normal SN I are obtained. In particular the expansion velocity on the edge of the incineration zone in a peculiar SN I is 2 - 3 times smaller than in a normal SN I. The author predicts the appearance of the strong emission lines from the unburnt matter of a supernova in the spectra of a peculiar SN I on the late time t > 40d. These lines must contain about 40% of the overall optical luminosity of the supernova.
