Abstract
A fuel injector, in particular for the direct injection of fuel into the combustion chamber of a mixture-compressing, externally fired internal combustion engine, comprising, upstream from a valve-seat surface, a swirl disk provided with swirl channels from which, given an open fuel injector, the fuel flows with a circumferential speed into a swirl chamber which is also located upstream from the valve-seat surface. Each point downstream from the swirl disk ( ) through which a flow is to pass has a larger extension in every spatial direction than the diameter of the swirl channels.
