1. A method for controlling combustion in a multi-cylinder engine, comprising: injecting fuel into at least one cylinder of the multi-cylinder engine;for each cylinder, separately controlling at least one fuel injection parameter to produce a desired exhaust composition for that cylinder, andcontrolling the at least one fuel injection parameter as a function of at least one engine operating condition, the at least one engine operating condition comprising at least one of atmospheric pressure, atmospheric temperature, engine load, and engine speed. 2. The method for controlling combustion as set forth in claim 1, wherein the at least one fuel injection parameter includes fuel injection timing. 3. The method for controlling combustion as set forth in claim 1, wherein the at least one fuel injection parameter includes fuel injection quantity. 4. The method for controlling combustion as set forth in claim 1, wherein the at least one fuel injection parameter includes fuel injection pressure. 5. The method for controlling combustion as set forth in claim 1, comprising introducing intake air into at least one cylinder. 6. The method for controlling combustion set forth in claim 5, comprising introducing EGR gas into at least one cylinder. 7. The method for controlling combustion as set forth in claim 1, comprising introducing EGR gas into at least one cylinder. 8. The method for controlling combustion as set forth in claim 1, comprising directing exhaust from at least one cylinder to a different location than exhaust from another cylinder. 9. The method for controlling combustion as set forth in claim 8, comprising directing exhaust from at least one cylinder to an EGR system so that it is introduced to at least one cylinder. 10. The method for controlling combustion as set forth in claim 9, comprising directing exhaust from at least one cylinder to an exhaust after-treatment system. 11. The method for controlling combustion as set forth in claim 1, comprising directing exhaust front at least one cylinder to an exhaust after-treatment system. 12. The method for controlling combustion as set forth in claim 1, comprising controlling the at least one fuel injection parameter for at least two of the cylinders to reduce exhaust composition variability between the at least two cylinders. 13. The method for controlling combustion as set forth in claim 1, comprising mixing exhaust from at least two of the cylinders and controlling the at least one fuel injection parameter for the at least two cylinders to achieve a desired exhaust composition of the exhaust mixture. 14. The method for controlling combustion as set forth in claim 1, comprising, for each cylinder, separately adjusting timing for at least one of an intake valve and an exhaust valve for the cylinder. 15. The method for controlling combustion as set forth in claim 1, comprising controlling the at least one fuel injection parameter as a function of at least a ratio of EGR gas and fresh intake air introduced into the cylinder to produce the desired exhaust composition for that cylinder. 16. The method for controlling combustion as set forth in claim 1, comprising controlling the at least one fuel injection parameter so that, for at least one cylinder, the at least one fuel injection parameter is different than the at least one fuel injection parameter for another cylinder. 17. A multi-cylinder engine, comprising: a plurality of cylinders;a fuel injector associated with each cylinder of the plurality of cylinders; anda controller arranged to separately control at least one fuel injection parameter for each cylinder to produce a desired exhaust composition for that cylinder as a function of at least one engine operating condition, the at least one engine operating condition comprising at least one of atmospheric pressure, atmospheric temperature, engine load, and engine speed. 18. The multi-cylinder engine as set forth in claim 17, comprising an intake air line for introducing intake air into at least one of the cylinders. 19. The multi-cylinder engine as set forth in claim 18, comprising an EGR system for introducing exhaust gas into at least one of the cylinders. 20. The multi-cylinder engine as set forth in claim 17, comprising an EGR system for introducing exhaust gas into at least one of the cylinders. 21. The multi-cylinder engine as set forth in claim 17, comprising an intake valve and an exhaust valve for each cylinder, the controller being arranged to separately adjust timing for at least one of the intake valve and the exhaust valve. 22. The multi-cylinder engine as set forth in claim 17, wherein the controller is arranged to control the at least one fuel injection parameter as a function of at least a ratio of EGR gas and fresh intake air introduced into the cylinder to produce the desired exhaust composition for that cylinder. 23. The multi-cylinder engine as set forth in claim 17, wherein the controller is arranged to control the at least one fuel injection parameter so that, for at least one cylinder, the at least one fuel injection parameter is different than the at least one fuel injection parameter for another cylinder.
