Patent number: 11377091Abstract: In a vehicle condition in which an engine rotation speed is likely to exceed a maximum rotation speed, since supercharging by a supercharger is curbed, it is possible to curb an increase in an engine torque. Even when the engine rotation speed exceeds the maximum rotation speed, the engine rotation speed is made less likely to increase by control of decreasing the engine torque. In a vehicle condition in which the engine rotation speed is less likely to exceed the maximum rotation speed, since a supercharging pressure becomes relatively high, it becomes easier to secure power performance. Accordingly, it is possible to curb a decrease in power performance due to curbing of supercharging and to prevent an engine from falling into a high-rotation state in which the engine rotation speed exceeds the maximum rotation speed.Type: GrantFiled: July 13, 2020Date of Patent: July 5, 2022Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Tooru Matsubara, Atsushi Tabata, Koichi Okuda, Yasutaka Tsuchida, Keisuke Omuro, Tetsuya Kono

Patent number: 11338790Abstract: Since a maximum rotation speed is set to a lower value when a supercharging pressure from a supercharger is high than when the supercharging pressure is low, an engine torque is decreased at a relatively low engine rotation speed and the engine rotation speed is less likely to fall into a high-rotation state. Since the maximum rotation speed is set to a relatively high value when the supercharging pressure is relatively low and the engine rotation speed is less likely to fall into a high-rotation state, the engine torque is not decreased at a relatively high engine rotation speed and power performance can be easily secured. Accordingly, it is possible to curb a decrease in power performance due to a decrease in the engine torque and to prevent the engine rotation speed from falling into a high-rotation state.Type: GrantFiled: July 8, 2020Date of Patent: May 24, 2022Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Atsushi Tabata, Koichi Okuda, Tooru Matsubara, Takashi Kohno, Yasutaka Tsuchida

Publication number: 20150040559Abstract: An intake-exhaust gas handling system for an internal combustion engine includes an intake system, an exhaust system, an intake cooler, and an exhaust gas recirculation (EGR) system. The intake system provides an intake charge, which can be a mixture of exhaust gas and air, to the internal combustion engine. The exhaust system removes exhaust gas generated by the internal combustion engine after a combustion process. The intake cooler can be disposed at the intake system for cooling the intake charge prior to its discharge into the internal combustion engine. The EGR system routes exhaust gas from the exhaust system to the intake system, where it is mixed with air at a position upstream of the intake cooler.Type: ApplicationFiled: August 7, 2013Publication date: February 12, 2015Applicant: Denso International America, Inc.Inventor: Patrick Powell

Patent number: 8950384Abstract: An example method for operating an internal combustion engine having at least one cylinder, at least one intake line for supplying charge air to the at least one cylinder, and a device for controlling charge-air flows conducted via a charge-air cooler and via a bypass line around the charge-air cooler is described, the device including a two-stage switchable shut-off element and a continuously adjustable shut-off element. In one example provided, the two-stage switchable shut-off element is arranged parallel to the bypass line in the at least one intake line, and is switched between an open position and a closed position, and the bypass line is opened up or shut off to a greater or lesser extent by the shut-off element which is continuously adjustable between an open position and a closed position. In this way, shuddering of the engine during shut down is prevented.Type: GrantFiled: June 29, 2012Date of Patent: February 10, 2015Assignee: Ford Global Technologies, LLCInventors: Christian Winge Vigild, Andreas Kuske, Daniel Roettger

Patent number: 8925526Abstract: A method of operating a combustion engine including causing an intake stroke in a first cylinder, causing a compression stroke in the first cylinder thereby creating pressurized fluid and releasing pressurized fluid from the first cylinder. The method further includes cooling the released fluid, directing the cooled fluid into a second cylinder over a first period of time and injecting fuel into the second cylinder over a second period of time whereby the first and second periods of time at least partially overlap.Type: GrantFiled: December 17, 2009Date of Patent: January 6, 2015Assignee: Caterpillar Inc.Inventors: Jonathan W. Anders, Scott B. Fiveland, Carl-Anders Hergart

Publication number: 20140360475Abstract: A cooling module, composed of at least one first and one second heat exchanger, are connected in a common frame or directly to one another, it being possible for cooling air to flow through both heat exchangers. The second heat exchanger has a greater structural depth than the first heat exchanger in the flow direction of the cooling air. The first heat exchanger and the second heat exchanger have a catalytic coating and the second heat exchanger is composed of at least one first and one second partial heat exchanger which are arranged one behind the other in the flow direction of the cooling air and which are operatively connected to one another. By means of the configuration according to the invention, the largest possible catalytically active coating surface area is attained.Type: ApplicationFiled: August 22, 2014Publication date: December 11, 2014Inventor: Stephan STUMPF
