Patent number: 8498798Abstract: A method for operating an internal combustion engine comprising an exhaust gas cleaning system that includes a SCR catalyst. In conjunction with a cold start and/or a warm-up of the internal combustion engine, the internal combustion engine is operated using a cold start engine operation method having predefineable values for predefineable operating parameters of the internal combustion engine. An amount of nitrogen oxides stored in the SCR catalyst is estimated, and the cold start engine operation method is activated when the estimation indicates that the nitrogen oxide storage amount exceeds a predefineable nitrogen oxide storage amount limit value.Type: GrantFiled: January 26, 2010Date of Patent: July 30, 2013Assignee: Daimler AGInventors: Thomas Koch, Alexander Massner, Anke Traebert

Publication number: 20130184970Abstract: A method is provided and may include monitoring operation of an engine of a vehicle, determining if the engine is started, and determining if the engine was started via an ignition or via a remote signal. The method may further include controlling operation of the engine at a first temperature if the engine was started via the ignition and controlling operation of the engine at a second temperature—different than the first temperature—if the engine was started via the remote signal. The second temperature may be higher than the first temperature to increase a temperature of coolant circulating within the engine.Type: ApplicationFiled: January 11, 2013Publication date: July 18, 2013Inventor: Fadi S. Kanafani

Patent number: 8489267Abstract: In a hybrid-electric vehicle that includes a cabin, methods and systems are provided for modifying a first curve for engine coolant temperature (ECT) warm-up trajectory. The system includes a processor configured to execute software instructions, and a memory configured to store software instructions accessible by the processor. In one embodiment, the software instructions comprise an offset lookup table that is configured to generate, based on a calculated thermal power loss across a heater core and an ambient air temperature, an offset value for modifying the first curve for ECT warm-up trajectory to produce a desired curve for ECT warm-up trajectory that is offset from the first curve. The desired curve for ECT warm up trajectory is used to adjust temperature in the cabin so that fuel consumption can be reduced.Type: GrantFiled: August 30, 2012Date of Patent: July 16, 2013Assignee: GM Global Technology Operations LLCInventors: Paul S.

Patent number: 8489310Abstract: In an apparatus for controlling a general-purpose internal combustion engine having an electronic control unit (ECU) mounted on an electronic circuit board installed near a body of the engine and being connectable to a load such as an operating machine that consumes power generated by the engine, there are equipped with a first temperature sensor installed on the board at a position remote from the body and a second temperature sensor installed on the board at a position closer to the body than the first temperature sensor. A warm-up time period is determined based on an output of the first temperature sensor and a difference between outputs of the first and second temperature sensors, and an engine speed is controlled to a predetermined operating speed when the determined warm-up time period has elapsed (S18, S22), thereby improving the fuel efficiency and preventing engine stall.Type: GrantFiled: April 20, 2010Date of Patent: July 16, 2013Assignee: Honda Motor Co., LtdInventors: Hideaki Shimamura, Takao Tamechika, Atsuhisa Ishikawa
