(1) Through the accumulation of many researches during 1974∼94 done by the authors [8∼12,15], as like temperature measurement or the calculation of it by normal flame propagation model, it was clarified the difficulty of explanation for the captioned theme shown in the title by the conventional past concept. (2) To conquer these issued problems a new hypothesis in which the burned gas jet from pre-chamber has mixed with premixed gas in the main-chamber and acted as same as internal EGR was proposed. (3) The calculated result of this hypothesis coincided qualitatively and quantitatively with the measured flame temperature and others that the appropriateness of this was verified. (4) The result of the state in combustion at A/F=18 has been in 7% of low oxygen concentration, 2350°K of high temperature and strong turbulent condition. (5) This paper suggests a new guideline for the target to lower NOx, lower fuel consumption by low oxygen, high temperature and strong turbulent combustion.
