An integrated and modular air and lighting plenum that is the primary directional lighting mounting apparatus and laminar flow diffuser of an HVAC system in a healthcare setting. The plenum provides laminar air flow from the ceiling to the room in which it is located in accordance with HVAC requirements for healthcare environment settings, by using a plurality of cylindrical airflow outlets. The use of cylindrical airflow outlets promotes laminar airflow by reducing sharp boundaries that induce turbulence (e.g., the corners of rectangular or square outlets) and creates a highly sterile environment around the patient and staff in the operating room. The surgical lights used in the integrated air and lighting plenum allow the beam direction, spot size, focal point, brightness, and color temperature of the emitted light to be controlled.

An internal combustion engine control device includes a NOx adsorber catalyst disposed in an exhaust passage, an EGR passage, a reducing agent adding device, a torque fluctuation reducing device, and a fuel injection device. The EGR passage draws a portion of exhaust gas from the exhaust passage downstream of the NOx adsorber catalyst and recirculates the exhaust gas into the intake passage. The reducing agent adding device adds a reducing agent to exhaust gas upstream of the NOx adsorber catalyst to reduce substances adsorbed by the NOx adsorber catalyst. When or after the reducing agent adding device adds the reducing agent, the torque fluctuation reducing device advances the timing of the fuel injection device or carries out a pilot injection to reduce a fluctuation in engine torque.
