Patent number: 9605602Abstract: A method of operating a gas or dual fuel engine having a plurality of cylinders, includes monitoring a characteristic of each of the plurality of cylinders during operation of the gas or dual fuel engine. The method also includes detecting a pre-ignition condition associated with one or more cylinders of the plurality of cylinders based on the monitored characteristic. The method further includes reducing fuel supply to the one or more cylinders having the pre-ignition condition. The fuel supply to remaining cylinders of the plurality of cylinders is increased, to maintain a constant power output of the gas or dual fuel engine. The method further includes adjusting an amount of air supplied to each of the plurality of cylinders based on the increased amount of fuel supplied to the remaining cylinders, to maintain an air-to-fuel ratio within a desired range.Type: GrantFiled: March 6, 2015Date of Patent: March 28, 2017Assignee: Caterpillar Motoren GmbH & Co. KGInventors: Eike Sixel, Adam Stubbs, Aradhita Subirkumar Chakrabarty, Daniel Wester, Rodney Stazicker, Michael Andrew Snopko, Arvind Sivasubramanian

Patent number: 9605604Abstract: Various systems and methods for controlling a turbocharger of an engine via a wastegate are described. In one example, the wastegate is adjusted according to a difference between the boost pressure and the atmospheric pressure. In this manner, the interdependency between controlling the boost pressure and using the boost pressure to actuate the wastegate in a boost-based wastegate configuration may be reduced.Type: GrantFiled: March 17, 2010Date of Patent: March 28, 2017Assignee: Ford Global Technologies, LLCInventors: Amey Y. Karnik, Mrdjan J. Jankovic

Patent number: 9605605Abstract: Provided is a vehicle control apparatus. To start an engine by a motor-generator under the state that a vehicle is stopped, the vehicle control apparatus synchronizes a rotation of the engine with a rotation of the motor-generator at a synchronous rotational speed lower than a target rotational speed to start the engine, and increases a rotational speed of the engine by the motor-generator from the synchronous rotational to the target rotational speed, and starts the engine at the target rotational speed.Type: GrantFiled: December 9, 2011Date of Patent: March 28, 2017Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Yukihiko Ideshio, Terufumi Miyazaki, Yuji Inoue, Shingo Eto, Yousuke Michikoshi

Patent number: 9605606Abstract: A method/system for optimizing vehicle operations for a predicted route and/or a route set. The method/system may record location data and time data for a route. Two or more routes can be linked to form a route set by analyzing the location data and time data of the routes using a linking threshold. The linking threshold may be based on a relationship between locations and/or times of different routes. The vehicle may predict that a particular route segment or route will likely be driven. An operation of a unit or a device of the vehicle over the predicted route and/or route set may be adjusted based on information stored regarding the predicted route and/or route set in order to enhance the energy efficiency of the vehicle. The links may be categorized as having different types in order to apply a different control strategy to different types of links.Type: GrantFiled: March 31, 2014Date of Patent: March 28, 2017Assignee: Toyota Motor Engineering & Manufacturing North America, Inc.Inventors: Mohammad E. Dufford, Joshua D. Payne, Geoffrey D. Gaither
