Embodiment Construction

[0010] in figure 1 In the illustrated embodiment, the cylinder head (1), the cylinder liner (2) and the piston (3) form an ω-type combustion chamber (4), and a fuel injector (8) is installed in the middle of the cylinder head (1). The outer side of the mouth (8) is a sleeve (5), and the lower end of the sleeve (5) is provided with an inner cone type guide cone. When the fuel injection nozzle (8) sprays an oil jet (6) toward the inner cone surface (5a) of the guide cone, the primary oil jet (6) expands into a more uniform circumferential direction under the guidance of the inner cone surface The secondary oil beam (7) forms a more homogeneous combustible mixture under the action of the air flow in the combustion chamber (4).

[0011] in figure 2 It shows that the inner cone guide cone is directly integrated with the cylinder head (1) and is located on the lower plane of the cylinder head (1) around the fuel injection nozzle (8).

[0012] In the above two embodiments, the same is t...

Abstract

The invention relates to an inner cone atomization system of an internal combustion engine which plays a guiding role and realizes secondary atomization, and belongs to the field of engine mixture gas formation and combustion. It is equipped with an inner cone guide cone directly above the fuel injector. When the oil beam ejected from the porous injector hits the guide cone, under the guidance of the inner cone surface, it forms a uniform distribution in the circumferential direction. The spray with good atomization and controllable penetration distance is very beneficial to the formation of combustible mixture, accelerates the combustion speed, and significantly improves the power, economy and emission indicators of the engine.

Description

Technical field [0001] The invention relates to an internal-cone atomization system of an internal combustion engine that plays a guiding role and realizes secondary atomization, and belongs to the field of engine mixture formation and combustion. Background technique [0002] At present, the excess air coefficient of diesel engines is large but it is easy to emit black smoke. The main reason is the unevenness of the porous spray in the circumferential direction and the excessively concentrated area at the point of spray. In order to solve this problem, the umbrella spray produced has good atomization performance and uniform distribution in the circumferential direction, but the penetration force is not strong. Therefore, the performance is better under medium and low working conditions. In high working conditions, the air around the combustion chamber cannot be used, and the black smoke increases more. Summary of the invention [0003] In order to solve the problems that the mi...
