Abstract: An example method for training a machine learning (ML) model in a server-client ML scenario includes determining by a ML service provider a set of rules for preparing input data, and preparing by a client input data according to the received set of rules based on raw data from an associated terminal device. The method further includes training a ML model by the ML service provider based on the prepared input data provided by the client.

Abstract: An injector sleeve adapted to be mounted in a cylinder head of an internal combustion engine, where the injector sleeve comprises a tapered inner surface which constitutes a sealing surface for an injector, where the hardness of the tapered inner surface is higher than the hardness of the outer surface of the injector sleeve. The injector sleeve is produced in a cold forming process. The advantage of the invention is that the injector sleeve is provided with a sealing surface for an injector which is harder than the outer surface of the injector sleeve. In this way, a sealing surface for an injector having small tolerances is obtained without further machining, where the outer surface may be turned to the desired dimensions.
