Abstract: A control system (12) for an engine (10) having a combustion chamber (22) is disclosed. The control system may have a fuel injector (40) configured to selectively inject fuel into the combustion chamber, and a controller (54) in communication with the fuel injector. The controller may be configured to activate the fuel injector during a first compression stroke to initiate fuel injection in an amount and at a timing that results in a stratified lean air/fuel mixture within the combustion chamber during a first combustion event of a six-stroke cycle. The controller may also be configured to activate the fuel injector during a first power stroke to initiate fuel injection in an amount and at a timing that results in a homogenous lean air/fuel mixture within the combustion chamber during a second combustion event of the same six-stroke cycle.

Abstract: A method and apparatus for authenticating entities to use an intelligent interactive Electronic Document Code stored in an RFID tag attached to a document as a means for third parties to ascertain a document is not counterfeit and has not been revoked or changed. In addition, such intelligent RFID tags can uniquely identify a particular document and data related to the document. The authenticating agency can utilize a public or private Electronic Document Code database as a means for the authenticating agency and third parties to authenticate documents and data in documents. The intelligent interactive Electronic Document Code can be used as an anti counterfeit mechanism enabling third parties requested to provide services, benefits or monetary payments to authenticate documents and or the data associated with the document is not counterfeit.

Abstract: A lubrication pump coupled to the engine is sized such that the it can supply the engine with a predetermined flow volume as soon as the engine reaches a peak torque engine speed. In engines that operate predominately at speeds above the peak torque engine speed, the lubrication pump is often producing lubrication fluid in excess of the predetermined flow volume that is bypassed back to a lubrication fluid source. This arguably results in wasted power. In order to more efficiently lubricate an engine, a lubrication circuit includes a lubrication pump and a variable delivery pump. The lubrication pump is operably coupled to the engine, and the variable delivery pump is in communication with a pump output controller that is operable to vary a lubrication fluid output from the variable delivery pump as a function of at least one of engine speed and lubrication flow volume or system pressure.
