Abstract: A filter element is disclosed. The filter element may include filter media extending circumferentially around and longitudinally along a longitudinal axis of the filter element. The filter element may also include pilot structure attached to the filter media and configured to locate the filter element. The pilot structure may include an axial cross-section that includes at least one of a noncircular feature or an asymmetrical feature relative to the longitudinal axis.

Abstract: Disclosed are various exemplary embodiments of an air cleaner assembly for a machine. The air cleaner assembly may include a filter housing and a filter element. The filter housing may include a mating surface extending in a first plane and defining a filter opening thereon. The filter housing also includes a filter engaging member associated with the mating surface. The filter element may include a filter frame extending generally in a second plane and defining an opening for receiving a filter medium. The filter element may also include a sealing member disposed in the filter frame around the opening and configured to seal around the opening when the filter frame is brought into contact with the mating surface. The filter element may further include a blade extending from the filter frame and configured to engage with the filter engaging member.

Abstract: Disclosed are various exemplary embodiments of a machine-readable code placed on an article and containing information relating to the article, where the code may be readable by a machine to retrieve the information. A portion of the code may be formed of a material that is reactive to a predetermined condition such that, when the article is subjected to the predetermined condition, the portion of the code may be changed to reflect in the information retrievable by the machine that the article has been subjected to the predetermined condition.

Abstract: A ventilation system for use with an internal combustion engine having a crankcase is disclosed. The ventilation system may have a breather housing connected to ventilate gases from the crankcase, and a filtration canister fluidly connected downstream of the breather housing. The filtration canister may have a filter housing, a filtering medium located within the filter housing to collect oil from the gases, and an oil collection container disposed within the filter housing and being configured to receive at least a portion of the filtering medium. The oil collection container may have a drain port in fluid communication with the crankcase. The filtration canister may also have at least one port configured to discharge the gases from the housing after the gases have passed through the filtering medium.
