Abstract

The invention discloses a nozzle core component which comprises a spray head component, a valve seat and a valve core component; a first channel is formed in the spray head component, the valve seat is arranged in the first channel, a blocking channel and an outflow channel are formed in the valve seat, and at least part of the valve core component is located in the blocking channel and can move in the blocking channel to be close to or away from the outflow channel; the valve seat is further provided with a third channel, and the third channel communicates with the first channel and the blocking channel; and at least the extending direction of an outlet of the third channel is the tangential direction of the inner circle, and the circle center of the inner circle is collinear with the central axis of the blocking channel, so that when flowing out of the third channel from the outlet, fuel rushes to the inner wall, opposite to the outlet, of the blocking channel, and is guided by the inner wall of the blocking channel, the fuel rotates in the blocking channel to form rotational flow, and thus atomization of the fuel is promoted, and the atomization quality of the fuel is guaranteed. The invention further discloses the fuel injector which comprises the nozzle core component and further comprises an electromagnet and an elastic piece, and the fuel injector is good in spraying effect.

Description

technical field [0001] The application relates to the technical field of fuel injection equipment for internal combustion engines, in particular to a nozzle core component and a fuel injector. Background technique [0002] The function of the fuel injector is to inject fuel into the intake port or cylinder in the form of atomization. The quality of fuel atomization will affect the performance of the engine, so there is a high requirement for the quality of the fuel injected into the engine, that is, There is a need for fuel injectors with better performance. [0003] Conventional fuel atomizing injectors usually have an arc track at the output end, so that the fuel flows along the arc track during the output process, thereby enhancing the swirling effect of the fuel and facilitating fuel atomization. The output structure of this type of injector is complex and difficult to process. Contents of the invention [0004] The purpose of this application is to overcome the defi...
