摘要： It is possible to decrease the amount of NOx emitted into the air. The amount of ammonia adsorbed on an SCR catalyst is calculated by subtracting the amount of ammonium nitrate produced on the SCR catalyst from the amount of ammonia adsorbed on the SCR catalyst at the time of starting of an internal combustion engine, and the amount of NO 2 flowing into the SCR catalyst is decreased when an NOx purification rate estimated from the amount of ammonia adsorbed on the SCR catalyst is less than a threshold value compared to when the NOx purification rate is equal to or greater than the threshold value.

摘要： A method and apparatus for operating a fuel-fired burner of an emission abatement assembly includes detecting a burner shutdown request, and adjusting an air-to-fuel ratio of an air/fuel mixture being supplied to the burner to a ratio greater than a stoichiometric ratio in response to the burner shutdown request. The method further includes advancing an adjusted air/fuel mixture to an electrode assembly of the burner for a predetermined amount of time in response to the burner shutdown request. The burner is shut down after the predetermined amount of time has elapsed.

摘要： A catalytic converter of an engine, such as might be found in an automotive engine system, is capable of being quickly and electrically heated in order to reduce pollution emissions during critical cold start conditions. During cold start conditions, i.e. upon starting the engine, for a predetermined period of time the catalytic converter directly receives electrical power via a quick heating path connecting a catalyst power switch to the catalytic converter. Following the predetermined period of time after which the catalytic converter has been electrically heated, the catalyst power switch is connected to a junction block, such as a starter motor assembly, of the automotive engine system via a normal path.

摘要： Systems, devices, methods and programs for reducing emissions from engines are provided. For example, one system for reducing emissions from engines comprises a heating controller coupled to an energy storage device (ESD). The heating controller is configured to control a heating element to heat one or more components of an after-treatment system using energy from the ESD under a first condition and to control the heating element to stop heating the one or more components of the after-treatment system when a second condition is satisfied. Additionally, another system for reducing emissions from engines comprises a controller detecting a decrease in a demanded torque from an engine and an ISG. The controller is then configured to operate a clutch to disengage the engine from the ISG, if after removing fuel from the engine, the sensed speed of the engine is above a threshold.

摘要： An engine (1) is provided with, in an exhaust passage (26), a urea aqueous solution supply mechanism (200) for supplying urea aqueous solution. The urea aqueous solution supply mechanism (200) includes a tank (210) for storing the urea aqueous solution, a pump (220) for delivering the urea aqueous solution, a supply pipe (240), a tank heater for heating the urea aqueous solution in the tank (210), a pump heater for heating the urea aqueous solution in the pump (220), and a passage heater for heating the urea aqueous solution in the supply pipe (240). A controller (80) adds urea by activating the pump (220) after heating control begins by way of the tank heater, pump heater, and passage heater. Then, the controller (80) outputs a signal indicating a tank heater abnormality when the urea aqueous solution pressure in the supply pipe (240) decreases while adding the urea and the amount of remaining urea aqueous solution detected by a level sensor (250) indicates that urea aqueous solution is remaining in the tank (210).
