Embodiment Construction
[0011] exist figure 1 In the shown embodiment, the cylinder head (1), the piston (2) and the cylinder liner (3) form an ω-shaped combustion chamber (2a), and the middle part of the cylinder head (1) is equipped with an oil injector (4), and the fuel injection The outside of the mouth (4) is a sleeve (5), and the lower end of the sleeve (5) is provided with a guide cone (5a) extending into the combustion chamber (2a). When the injector (4) sprays the primary oil jet (4a) toward the guide cone (5a), the primary oil jet (4a) expands into a more uniform circumferentially distributed secondary oil jet under the guidance of the guide cone (6), the secondary oil beam (6) forms a more homogeneous combustible mixture under the action of the airflow movement in the combustion chamber (2a).
[0012] exist figure 2 Showed that the guide cone (5a) is a structure that is connected with the conduit (5) by two connecting ribs (5b).
