Applied ignition internal combustion engine whose pistons have elliptical recesses |
摘要 |
The present invention relates to an applied ignition internal combustion engine having at least one cylinder in which a piston slides along the cylinder axis, with a cylinder head capping the cylinder and, together with the piston and cylinder, defining a combustion chamber. The piston has a recess open toward the cylinder head, the recess having several shapes of an ellipsoid section along a transverse plane of the piston, of which the main axis and generatrices are substantially parallel to the lengthwise axis of the piston in order to reduce the area-volume ratios in the combustion chamber and increase turbulence levels at the end of the compression cycle. The ellipse or ellipses is or are such that: 1) 0< lambda <0.6 with <IMAGE> where GR is the major radius of at least one of the spaces PR is the minor radius of the space or spaces.
