    • PROBLEM TO BE SOLVED: To provide a pre-mixed compression self-firing combustion engine capable of realizing stabilization of combustion and reduction of noise even at high load operation. SOLUTION: A heat insulation part 15 is formed on a central part of an apex of a piston 4 constituting a partial wall surface of a combustion chamber 14. Cooing of a mixed gas is suppressed near the heat insulation part 15 when a pressure and a temperature of the mixed gas in the combustion chamber 14 are raised accompanying with ascending of the piston and a high temperature portion is formed here. Therefore, a predetermined temperature distribution that the temperature is not concentrated to a some temperature range is formed in the combustion chamber 14 and when firing occurs at the maximum temperature portion, combustion gradually occurs according to the temperature distribution, the mixed air in the combustion chamber 14 is not burned at a stretch and combustion of the mixed gas is relaxed. Further, the predetermined temperature distribution can be formed by arranging the heat insulation part 15 and the maximum temperature portion becoming the firing starting place can be spatially defined.

    • PURPOSE:To moderate shocks caused at the time of switching use of oxygen- enriched air and ordinary air supplied to a combustion chamber according to the operational conditions of an engine, by providing a control means for controlling switching of air to be use so that the switching speed is made slow, in an air intake apparatus for engine comprising an oxygen enriching means. CONSTITUTION:An oxygen enriching means 23 increases the rate of oxygen contained in air by passing much oxygen through an oxygen-permeable membrane 15 by the function of pressure difference on the opposite sides of the membrane 15 that is produced through operation of a feed pump 16 and a suction pump 17. The oxygen-enriched air thus obtained is supplied to a combustion chamber 1a via a supply passage 13 when an oxygen-density control valve 18 is opened and a relief valve 22 is closed. In such an arrangement, switching of the oxygen- enriched air and ordinary air supplied from a main intake passage 2 is achieved by controlling the control valve 18 and the relief valve 22 by means of a control circuit 8. Here, the switching speed is controlled to be slow by an operation control means consisting of an integration circuit, etc. in the control circuit 8.
