Internal combustion engine guide collision burning system

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.

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.
