Abstract: PROBLEM TO BE SOLVED: To provide a technique which prevents peeling of melt-sprayed coating on an inner surface of a bore of a cylinder block. SOLUTION: A melt-spraying device 10 is provided with a melt-spraying gun 14 inserted in a bore 12 from one side of an opening of the bore 12 which penetrates a cylinder block 11, and a magnetic field generator 24 which generates in the inside of the bore 12 a magnetic field which gives an attracting action to unmolten particles toward the other side of the opening of the bore 12. When metal such as iron used for a melt-spraying particle 15 reaches a high temperature enough to melt, it has a property not to be attracted to a magnetic field. When a magnetic field which is sucked toward the opening of the bore 12 is generated and melt-sprayed in the inside of the bore 12, while the molten melt-spraying particles 15 are sprayed on the inner surface of the bore 12 affected by no influence of the magnetic field, unmolten melt-spraying particles 37 will be sucked to the opening side of the bore 12 and will not reach an inner surface of the bore 12 affected by the influence of the magnetic field. For this reason, the good melt-sprayed coating 17 is formed which is made of only spray particles 15, or of spray particles with a low mixing ratio of the unmolten particles 37 on the inner surface of the bore 12.

Abstract: PROBLEM TO BE SOLVED: To provide a piston structure for a direct injection type engine capable of reducing the emission of unburned hydrocarbon and a particulate matter. SOLUTION: A piston 10 includes an annular groove 14 having a bowl shape cross section between an inner circumference wall surface 12a and an inner bottom wall surface 12b of a concave part 12. The concave part 12 has different cross section shape at a plurality of first cross section zones positioned near a plurality of fuel spray axis lines 21c and a second cross section zone positioned near the center of the plurality of fuel spray axis lines 21c. First collision angles α1 in a direction in which the plurality of fuel spray axis lines 21c separate from a tangential line position passing on a collision point of a fuel spray and inner wall surfaces 12a, 12d of the concave part 12 in the first cross section zones are set larger than second collision angles α2 in a direction in which a cone surface 21c' including the plurality of fuel spray axis lines 21c separates from the inner wall surface 12a in the second cross section zone. The annular groove 14 having the bowl shape cross section is formed deep in the first cross section zones to enlarge the bowl shape cross section and shallow in the second cross section zone.
