Definitions
- It relates more precisely to a method for adjusting the distribution of the recirculation rate of the exhaust gases at the intake of a diesel engine between, on the one hand, a partial recirculation rate at low pressure and, on the other hand , a rate of partial recirculation at high pressure of said exhaust gases.
- step 700 the volume flow rate of exhaust gas Qech, vol at the inlet of the first depollution device is calculated, from the (mass) flow rate Qech calculated in step 500, using the ideal gas equation and from the pressure and temperature at the inlet or in said device.
