    摘要： A rare earth magnet in which the amount used of a heavy rare earth element is more reduced while maintaining enhancement of the coercive force, and a producing method thereof are provided.
    The rare earth magnet of the present disclosure has a main phase (10) and a grain boundary phase (20). The main phase (10) has a composition represented by, in molar ratio, R 1 2 T 14 B (R 1 is a rare earth element, etc. and T is a predetermined transition element, etc.). The main phase (10) has a core part (12) and a shell part (14). Denoting the abundances of R 2 and Ce (R 2 is a predetermined heavy rare earth element) occupying 4f site of the shell part (14) as R 2 4f and Ce 4f , respectively, and denoting the abundances of R 2 and Ce occupying 4g site of the shell part (14) as R 2 4g and Ce 4g , respectively, the rare earth magnet satisfies 0.44≤R 2 4g /(R 2 4f +R 2 4g )≤0.70 and 0.04≤(Ce 4f +Ce 4g )/(R 2 4f +R 2 4g ). The rare earth magnet-producing method of the present disclosure uses a modifier containing at least R 2 and Ce.

    摘要： In a stratification operation, O 2 is injected from an oxygen injector 24 during valve opening of an intake valve 26. Therefore, the injected O 2 flows into a combustion chamber 14 immediately after the injection, and forms a layer having a constant spread in the combustion chamber 14 (A in Figure 5 ). Meanwhile, the working gas in the combustion chamber 14 forms such a layer as to cover the O 2 layer on a wall surface of the combustion chamber 14 in conjunction with formation of the O 2 layer (B in Figure 5 ). In other words, in the combustion chamber 14, an inner layer with a high O 2 concentration (A in Figure 5 ) and an outer layer with a high working gas concentration (B in Figure 5 ) are respectively formed.
