Embodiment Construction
[0016] exist figure 1 , 2 , In the embodiment shown in 3, 4, this collision spray squish flow combustion system mainly has a combustion chamber 4 that is made up of cylinder head 1, cylinder liner 2 and piston 3, and fuel injection nozzle 5 uses multi-beam mode to inject high-pressure fuel It is sprayed into the combustion chamber 4 in the form of mist to form a combustible mixture, and a protrusion 8 is provided in the center of the piston 3 . The protrusion 8 is made up of fan surfaces radially and continuously distributed with the convex top 9 as the center, each fan surface forms an intersecting top edge 11 with the adjacent side folding fan surface, and forms an intersecting top edge 11 with the adjacent other side folding fan surface. The bottom edge 12; the fuel injection nozzle 5 is located above the convex top 9.
[0017] figure 1 , 2 An embodiment is shown, figure 2 yes figure 1 A three-dimensional schematic of the middle bump 8. The center of the piston 3 is...
