Embodiment Construction

[0018] exist figure 1 , 2 In the shown embodiment, a main combustion chamber 4 is formed by the cylinder liner 1, the cylinder head 2 and the piston 3; a guide ring 5 is arranged on the periphery of the fuel injection nozzle 6, figure 1 The guide ring in is set separately, figure 2 The guide ring 5 is integrated with the cylinder head. The lower end of the guide ring 5 is provided with a planar guide surface 5a for the primary oil jet, and the planar guide surface 5a is located on the path of the primary oil jet 6a sprayed out by the fuel injection nozzle 6 . The fuel injection nozzle 6 ejects 6 primary oil jets 6a to the 6 planar guide surfaces 5a, and under the guidance of the planar guide surfaces 5a, 6 secondary oil jets 6b are formed, and the 6 secondary oil jets 6b can basically be Cover the whole main combustion chamber 4.

Abstract

The present invention relates to a guide collision combustion system of internal combustion engine, belonging to the field of engine mixed gas formation and combustion technology. It is characterized by that the lower end of guide ring placed on the periphery of fuel nozzle is equipped with a guide surface of primary fuel beam, and the moulding surface of the guide surface, circumferential included angle alpha and longitudinal included angle beta can be defined after copulation experiment. The primary fuel beam injected from fuel nozzle can be spread along the guide surface, and can be injected in the sector form so as to implement secondary atomization, so that it can greatly improve quality of engine combustible mixed gas and can make the combustion quick and complete.

Description

technical field [0001] The invention relates to a guided collision combustion system of an internal combustion engine, which belongs to the field of engine mixture gas formation and combustion. 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...
