    Abstract: An ECU corrects a fuel addition interval, based on an amount of change between an exhaust gas temperature at present and a basic exhaust gas temperature obtained when a basic addition interval is set, to reduce the fuel addition interval with an increase in the amount of change in the exhaust gas temperature. With such correction of the addition interval, when the exhaust gas temperature is increased in a highland region or the like, the fuel addition interval is corrected to be reduced and an fuel addition amount is corrected to be increased according to the increase in the exhaust gas temperature. Thereby, an increase in a temperature at a tip portion of a fuel addition valve can be suppressed, and thus clogging of an ejection hole of the fuel addition valve with deposits can be avoided.

    Abstract: An exhaust gas purification system for a hybrid vehicle is disclosed. An internal combustion engine and an electric motor are each arranged for providing power output for the vehicle. An exhaust gas purification device is provided in an exhaust gas passage of the engine to treat exhaust gas components contained in the exhaust gas from the engine. A controller is arranged and configured to selectively perform a regeneration operation of the exhaust gas purification device to burn and remove deposits accumulated in the exhaust gas purification device. The controller is further arranged and configured to control the internal combustion engine and the electric motor such that the exhaust gas purification device is restrained from reaching an excessive temperature during the regeneration operation of the exhaust gas purification device.

    Abstract: A hood assembly for a machine includes an enclosure within which at least one exhaust aftertreatment device is mounted. The engine hood assembly may be preassembled so that the exhaust aftertreatment system is integrated into the enclosure. This may allow the hood assembly to be assembled to the machine and the exhaust aftertreatment system mated to an exhaust pipe from the engine as a unit while the machine is being built on an assembly line. The engine hood assembly may include ventilation openings to assist in heat rejection from the engine compartment and from the exhaust aftertreatment devices. The hood assembly of the present disclosure finds particular application in assisting large track type tractors in meeting ever more stringent exhaust emission requirements without extensive and expensive redesign alternatives.

    Abstract: A method of dosing a reagent into an exhaust gas stream of an internal combustion engine having an SCR catalyst, the method comprising injecting reagent from a reagent tank into the exhaust gas stream at a position upstream of the SCR catalyst using a reagent injector in accordance with a first dosing schedule in order to remediate a predetermined proportion of NOx in the exhaust gas stream, the first dosing schedule being associated with a first range of engine operating conditions; and injecting reagent from the reagent tank into the exhaust gas stream at a position upstream of the SCR catalyst using a reagent injector in accordance with a second dosing schedule in order to enable heat transfer between the reagent injector and said injected reagent, the second dosing schedule being associated with a second range of engine operating conditions.Dosing in accordance with said first or said second dosing schedule is carried out in dependence on whether engine operating conditions lie within said first or said second range of engine operating conditions, and the proportion of NOx in the exhaust gas stream which is remediated by dosing using said second dosing schedule is less than said predetermined portion. A reagent dosing system is also provided for dosing a reagent into the exhaust gas stream of an internal combustion engine, comprising a reagent tank for storing a supply of reagent, an injector module comprising an atomising dispenser and a positive-displacement metering pump which draws reagent from the reagent tank and delivers it to the dispenser a supply line coupling the reagent tank to the injector module, and a dosing control unit operable to control the injector module to inject reagent into the exhaust gas stream. A priming pump is provided to urge reagent along the supply line toward the injector module under selected conditions.
