An apparatus for an internal combustion engine controls engine timing as a function of engine load, speed and air intake temperature to reduce engine NOx emissions and/or engine fuel consumption. The apparatus is particularly beneficial to a large, aftercooled turbocharged engine which utilizes a cooling system having a liquid cooled, separate circuit aftercooler (SCAC) to cool the pressurized intake air. By routing the aftercooler circuit and engine coolant circuit through a common or single core radiator, the aftercooler cooling circuit temperature and associated engine air intake temperature are reduced to further reduce engine NOx emissions and/or engine fuel consumption.
