エンジンの可変圧縮比機構。 In a swirl chamber type diesel engine equipped with a glow plug, a flange integrally formed with the glow plug, a first compression spring disposed between the flange and a bottom wall of a storage hole housing the glow plug; a second compression spring facing the first compression spring and disposed between the flange and the upper wall of the storage hole, at least one of the first compression spring and the second compression spring; By making one of the springs a shape memory alloy spring with temperature load characteristics, the glow plug can be moved in the axial direction depending on whether the temperature is low or high, and its tip can be moved into or out of the vortex chamber. Variable compression ratio mechanism for swirl chamber type diesel engines.
