The described empirical investigations deliver the input parameters for the simulation model, in which the exhaust gas flow rate, the exhaust gas temperature, and the N[O.sub.2]/N[O.sub.x] ratio at the entrance of the exhaust gas after treatment system represent the most important variables.
The engine experiments show that exhaust gas temperature and mass flow are increased by lower injection pressures and as expected the effect is slight and mostly noticeable at very low pressures below 50 bar.

The inlet to the rig exhaust network was attached several meters downstream of a natural gas burner capable of generating exhaust gas temperatures of up to 1000 [degrees]C and mass flow rates of up to 750 kg/hr.
Further, it is necessary to ensure the exhaust gas temperature out of the heat exchanger higher than 200[degrees]C in order to avoid the dew point corrosive phenomenon.
Water is the preferable working fluid for high exhaust gas temperature due to its high evaporation enthalpy and thus higher power output and thermal efficiency.
Many LTHW boilers are limited to a turndown of just 2:1 or 3:1 to ensure that the boiler exhaust gas temperatures are maintained above the 130-140[degrees]C required to avoid condensation.
The exhaust gas temperature and flow rate with increasing the engine load is increased.
Another problem can occur when an engine is shut down quickly after being operated at high speed and load where the exhaust gas temperature is maximized.
