Abstract: A locomotive consist includes a first locomotive unit that receives a power command from a throttle signal or a dynamic brake signal from MU trainlines, a second locomotive unit with an energy storage system electrically connected to one or more second unit traction motors, and a hybrid control system on the first locomotive unit. The hybrid control system intercepts the throttle signal or the dynamic brake signal from the MU trainlines, calculates first and second alternate power commands for the first and second locomotive units, respectively, that when added together equal the power command received on the MU trainlines, communicates the first power command to the first locomotive prime engine or dynamic braking system, and communicates the second power command to the second locomotive unit.

Abstract: An object is to prevent abrasion inside an addition valve and clogging of the addition valve due to an increase in the particle diameter of precipitates. A first control is performed by which a pump is caused to operate in such a way as to return urea solution contained in the addition valve and a urea solution channel to a tank by a predetermined quantity. After the lapse of a certain time after the end of the first control, a second control is performed by which the pump is caused to operate in such a way as to return the urea solution remaining in the addition valve and the urea solution channel thoroughly to the tank.

Abstract: In a method of operating an exhaust emission control device, the presence of an actual pressure loss of a particulate filter is determined, and a model pressure loss is determined as a function of a state variable. On the basis of the actual pressure loss and the model pressure loss a pressure quotient is determined and a condition of the particulate filter is ascertained in a diagnostic mode in response to the pressure quotient.

Abstract: A method for regenerating a lean NOx trap (LNT) of an exhaust purification system having the LNT and a selective catalytic reduction (SCR) catalyst includes determining whether a regeneration release condition of the LNT is satisfied; determining whether a regeneration demand condition of the LNT is satisfied; and performing regeneration of the LNT if the regeneration release condition of the LNT and the regeneration demand condition of the LNT are satisfied, wherein satisfaction of the regeneration release condition of the LNT is determined based on an NOx amount absorbed in the LNT, an NH3 amount stored in the SCR catalyst and temperature at an upstream of the SCR catalyst.

Abstract: In a method of reducing pollutants of a combustion engine, exhaust gas, generated by a cylinder of the combustion engine, is fed to an exhaust gas aftertreatment system as a function of a predefined condition solely via a first exhaust channel which communicates with a first one of first and second exhaust valves of the cylinder. The first exhaust channel is hereby coated, at least in part, by a thermally insulating layer selected such that a heat input is transmitted to the exhaust gas aftertreatment system which heat input is greater than a heat input in a second exhaust channel communicating with a second one of the first and second exhaust valves. The predefined condition is defined as a function of a coolant temperature of the combustion engine.

Abstract: A method and system for operating an aftertreatment system of an internal combustion engine is disclosed. A value of a storage efficiency for the lean nitrogen-oxide trap is determined. A value of an exhaust gas temperature is measured upstream of the lean nitrogen-oxide trap. An electric heated catalyst enabling condition may be fulfilled if the storage efficiency of the lean nitrogen-oxide trap is smaller than a threshold value thereof and the value of the exhaust gas temperature upstream of the lean nitrogen-oxide trap is greater than a lower threshold value and less than an upper threshold value. The electric heated catalyst is activated if the enabling condition is fulfilled. An inhibition enabling condition may be fulfilled if the value of storage efficiency is less than a second threshold value and the electric heated catalyst is deactivated and a denitrification of the lean nitrogen-oxides trap is started.

Abstract: A catalyst regeneration processing apparatus for an internal-combustion engine includes an electronic control unit. The electronic control unit is configured to determine whether a gap is equal to a predetermined degree or less, the gap being a difference between (a) a progress degree of heat deterioration of a NOx catalyst in a predetermined time in a case of assuming that a regeneration process is executed for the predetermined time and (b) a progress degree of heat deterioration of the NOx catalyst in the predetermined time in a case of assuming that the regeneration process is not executed. The electronic control unit is configured to execute the regeneration process in a case of determining that the gap is equal to the predetermined degree or less, even when a sulfur poisoning quantity does not exceed a permissible upper limit quantity.
