Embodiment Construction

[0012] exist figure 1 , 2 In the shown embodiment, an ω-shaped combustion chamber (4) is formed by the cylinder head (1), the cylinder liner (2) and the piston (3). The oil injector (9) sprays 6 primary oil beams (7) to the 6 guide vanes (6), and under the guidance of the guide surface of the guide vanes (6), 6 secondary oil beams (8) are formed, and the 6 The secondary oil beam (8) can basically cover the entire combustion chamber (4). The guide vanes (6) are fixed on the casing (5) installed in the cylinder head (1) through connecting ribs (5a).

[0013] exist image 3 , 4 In another embodiment shown, an ω-shaped combustion chamber (4) composed of a cylinder head (1), a cylinder liner (2) and a piston (3), guide vanes (6) are connected together to form an annular body (10), the annular body (10) is fixed on the sleeve pipe (5) installed in the cylinder head (1) by 3 connecting ribs (5a). The oil injector (9) sprays 6 primary oil beams (7), and under the guidance of the...

Abstract

A combustion system with guide blade for IC engine features that the guide blades are arranged under the oil nozzle. When the oil beam is sprayed onto the guide blades, its surface can quickly spreadit for realizing secondary atomizing. Its advantages are uniform high-quality atomizing, and high combustion speed.

Description

technical field [0001] The invention relates to a combustion system of guide blades of an internal combustion engine, which belongs to the field of formation and combustion of engine mixed gas. Background technique [0002] At present, the excess air coefficient of the diesel engine is relatively large, but it is easy to emit black smoke. The main reason is that the porous spray is not uniform in the circumferential direction, and an over-concentrated area is generated at the spray point. In order to solve this problem, although the umbrella-shaped spray produced has good atomization performance and uniform distribution in the circumferential direction, the penetrating force is not strong. Therefore, the performance is better under medium and low working conditions, and the black smoke increases more under high working conditions because the surrounding air of the combustion chamber cannot be used. Contents of the invention [0003] In order to solve the problems of too t...
