exhaust flows out from engine 16 passing either to an egr cooler 24 or past turbocharger turbine 30 the exhaust gas flow past turbocharger turbine 30 causes it to rotate and drives turbocharger compressor 20 the exhaust gas flows by gas sensor 40 and then continues through diesel oxidization catalyst 32 and particulate filter 34 and the remaining gas is exhausted to the ambient atmosphere the exhaust gas that flows by gas sensor 40 has a particular nox and or oxygen content which is sensed by gas sensor 40 the exhaust gas that is diverted through the exhaust gas recirculation system first goes through a cooling process by egr cooler 24 and egr valve 26 is under the control of controller 36 which can moderate the flow or completely shut off the flow of the egr exhaust gas that is recirculated may enter directly into egr mixer 28 rather than into the flow as shown in fig2 controller 36 is communicatively connected to speed sensor 38 gas sensor 40 fuel metering device 42 and egr valve 26 now additionally referring to fig3 and 4 there is illustrated methods 100 and 150 that carry out the control steps of the present invention the steps may be carried out by way of hardware an algorithm stored in controller 36 or a combination of hardware and software at step 102 there is a detection of an increase in torque requirement for engine 16 that is sensed by speed sensor 38 and conveyed to controller 36 although schematically.
