An engine control unit performs homogeneous charge combustion with a rich air-fuel ratio when a NOx absorption material has absorbed a specified amount of NOx absorption so as to purge NOx and to reduce the NOx with HC and CO in an exhaust gas, thereby purifying the exhaust gas. During execution of
An engine control unit performs homogeneous charge combustion with a rich air-fuel ratio when a NOx absorption material has absorbed a specified amount of NOx absorption so as to purge NOx and to reduce the NOx with HC and CO in an exhaust gas, thereby purifying the exhaust gas. During execution of the homogeneous charge combustion, a pressure of fuel with which a fuel injector sprays fuel is held at a pressure level for stratified charge combustion immediately before an alteration to the homogeneous charge combustion so as thereby to eliminate an occurrence of a time delay in changing the pressure of fuel upon resumption of the stratified charge combustion from the homogeneous charge combustion executed for NOx purge with an effect of preventing a fuel mixture from falling into the difficulty that the fuel mixture is hard to concentrate locally around a spark plug.

A drum assembly for a window regulator comprising: a drum including an axial bore and including a circumference with a cable aperture; a biasing assembly having a resilient member coacting with said bore and generating a force on said bore to expand said circumference; and wherein said drum includes a plurality of radial grooves defining a plurality of sectors with said sectors movable relative to one another in response to said resilient member forcing said mandrel into said bore to expand said circumference. 14. A method of taking up slack in a window regulator assembly comprising the steps of: a) providing a window regulator assembly with a drum and cable; b) expanding a circumference of the drum by urging a mandrel into a bore in the drum; and c) wrapping the cable around the drum. 15. The method according to claim 14, wherein step b) forcing a plurality of radial drum sectors away from one another.
