Abstract: The invention relates to the technology of gasoline direct injection (GDI) in automotive engines. In this context, the invention provides a method for maximizing the formation of deposits in injector nozzles of GDI engines, said method including at least one test cycle, each test cycle including at least one testing step in which a predetermined condition of speed and load of the GDI engine is maintained for a specified period of time, wherein, in said cycle, in at least one testing step, the engine speed is maintained between 1300 and 3700 rpm, the engine load is maintained between 10 and 80% and the specified period of time is from 10 to 200 minutes. Thus, the method of the invention is able to reproduce severe conditions of deposition of material in a few days, so that, in a short period of time, the test fuel can be assessed for tendency to form deposits.

Abstract: A crowd-sourcing system performs a method that includes generating a request that a user provide candidate media data to the crowd-sourcing system. The candidate media is descriptive of a product, and the request includes information about the product. The crowd-sourcing system transmits the request to a user system and receives the candidate media data from the user system. The crowd-sourcing system selects the candidate media data as stock media data for the product. The selection of the candidate media data may be based on a selection criterion, such as a grade of the candidate media data determined by the crowd-sourcing system. The crowd-sourcing system provides a reward to the user based on the selecting of the candidate media data as the stock media data for the product.

Abstract: Methods and systems to generate product records in catalogs from divergent listings are provided. Example systems include a listings module to identify an immature product record corresponding to the item for sale. The listings module may determine, from one or more attributes of an item for sale described by the listing, that the item can be matched to an immature product record. A voting module may provide an interface including the first version of the immature product record and an option to select a first version or a second version of the immature product record matching the item. The voting module may further relate the selected version to the item for sale based on a selection by a user, and, in response, update a count of votes for the selected version. When the count of votes meets a threshold, the selected version may become the mature product record for inclusion in a catalog.
