Abstract: A disinfection apparatus for disinfecting an object is disclosed. The disinfection apparatus comprises at least one disinfection unit operable to perform a disinfection operation on the object to be disinfected, an outer casing and at least one actuating door. The outer casing and the at least one actuating door define a disinfection compartment. The apparatus includes at least one position sensor for detecting the presence of an object to be disinfected having been positioned within the disinfection compartment, at least one obstruction sensor operable to detect whether at least a first safety zone is clear, and a central control unit, the central control unit being operable to control operation of the at least one actuating door, the at least one position sensor, the at least one obstruction sensor, and the at least one disinfection unit.

Abstract: A method of operating a combustion apparatus (10) having an engine (12) and an air processing unit (14) comprises: separating inlet air in the air processing unit (14) into oxygen enriched air and nitrogen enriched air; delivering oxygen enriched air to the engine (12) and initiating homogeneous charge compression ignition combustion, and then reducing the mass of oxygen enriched air being delivered to the engine (12) and maintaining homogeneous charge compression ignition combustion.

Abstract: An air intake system for a combustion apparatus is described. The system comprises an air separator (16, 116, 216, 316) having an inlet for receiving air and an outlet, the outlet adapted to be coupled to an air intake of a combustion apparatus, wherein the air separator comprises a zeolite material adapted to absorb a portion of nitrogen from air received therein. In one embodiment the combustion apparatus is an internal combustion engine (14, 114, 214, 314).
