A system for providing air to an internal combustion engine comprises a crankcase ventilation unit that receives unrefined blowby gas from a crankcase, separates oil from the unrefined blowby gas, and discharges refined blowby gas. A conduit delivers the refined blowby gas to an air cleaner housing. The air cleaner housing comprises a first chamber that receives intake air through a first port, a second chamber that receives intake air from the first chamber and refined blowby gas from the conduit through a second port, and a third chamber that receives a mixture of intake air and refined blowby gas from the second chamber and discharges the mixture through a third port. A primary filter element filters the intake air as it passes from the first chamber to the second chamber. A secondary filter element filters the mixture as it passes from the second chamber to the third chamber.

Currency bills are transported past an image scanner to one or more output receptacles. Each of the bills is imaged to produce image data from which a visually readable image of each bill can be reproduced. The serial number, denomination, and/or secondary identifiers of a bill is attempted to be extracted and/or determined from the image data associated with the bill. The serial number of the bill has an integer number, X, of characters. One or more of the X characters of the serial number of the currency bill is not extracted with a predetermined confidence. In response to failing to extract all of the X characters of the serial number of the bill with the predetermined confidence, a serial number field in an electronic record associated with the bill is populated with a serial number snippet image. The electronic record is stored in a non-transitory memory.

This project will demonstrate a novel cost effective compact diesel electric propulsion system initially for bus vehicle application that fits within the current space envelope of a diesel engine and, due to its wide application (as it is suitable for retrofit as well as new build), will deliver significant reductions in CO2 emissions compared to current best in class technologies. The consortium assembled (Cummins; Dynex; Castlet and the University of Nottingham) along with involvement from key UK bus vehicle manufacturers provides strong supply chain representation to support the UK automotive industry realise the global potential associated with the demand for lower-carbon transportation. It is anticipated the propulsion system will deliver significant bus vehicle CO2 emission reduction compared to current best-in class at a negligible cost increment over current diesel variants. Cummins will build on research undertaken to date to develop, demonstrate and commercialise the propulsion system through its global network (Cummins currently has ~20% of the global bus engine market).
