A method for operating a homogeneous-charge-compression-ignition (HCCI) engine at low speed includes the steps of monitoring the operating speed and load of the HCCI engine in a stable combustion condition. When the engine cylinder load drops below a predetermined value equal to the lowest allowed load at its current engine speed, at least one cylinder is deactivated to maintain the stable combustion in the remaining activated cylinders. When the cylinder load exceeds another predetermined value at its current engine operating speed, the cylinder is reactivated.

The tie-out system of claim 11, the base portion of the channeled base comprising a pair of opposing apertures configured to receive therethrough a pair of bolts so as to couple the tie-out system to the trailer. 13. The tie-out system of claim 11, the opposing sides of the channeled base each comprising at least one beveled corner portion configured to provide clearance for the flexible portion as the connector rotates in the receiver. 14. The tie-out system of claim 11, the upper portion of the connector comprising at least one face thereon, the first end portion of the flexible portion coupled to the at least one face. 15. The tie-out of claim 1, the receiver and the lower portion of the connector each comprising aligning apertures configured to removably receive a securing pin to removably couple the lower portion of the connector within the receiver. 16. The tie-out system of claim 15, the lower portion of the connector comprising a pair of aligning apertures. 17. The tie-out of claim 16, the pair of aligning apertures intersecting and oriented substantially perpendicular to one another. 18. The tie-out system of claim 11, the tie-out comprising a rigid portion having a first end portion and a second end portion, the first end portion of the rigid portion coupled to the second end portion of the flexible portion. 19. The tie-out system of claim 18, wherein the rigid portion is one of a bar and a pipe. 20. The tie-out system of claim 19, wherein the bar is cylindrical and the pipe is annularly cylindrical. 21. A tie-out system for use with a trailer, the tie-out system comprising: a channeled base configured to couple to the trailer, the channeled base comprising a base portion having opposing sides extending outwardly and substantially perpendicular therefrom, the base portion comprising a pair of opposing apertures configured to receive therethrough a pair of bolts so as to couple the tie-out system to the trailer, the opposing sides each comprising beveled corner portions configured to provide clearance for the flexible portion as the connector rotates in the receiver; an annularly cylindrical receiver configured to removably and rotatingly receive a connector, the receiver coupled to the opposing sides of the channeled base; the connector configured to rotate within the receiver and to removably couple the receiver to a tie-out, the connector comprising a cylindrical lower portion and a partially obround upper portion comprising at least one face thereon, the lower portion removably and rotatingly coupled within the receiver, the receiver and the lower portion of the connector each comprising aligning apertures configured to removably receive a securing pin to removably couple
