20080264059 | Control apparatus and control method for negative pressure generating apparatus - A control apparatus for a negative pressure generating apparatus includes an ejector that generates a negative pressure whose magnitude is larger than that of a negative pressure to be taken from an intake passage in an intake system for an internal combustion engine provided in a vehicle; a state change device that makes the ejector function or stop functioning; and a predetermined value change device that changes a predetermined value according to an operating state of the vehicle, when the state change device makes the ejector function based on a result of a comparison between the negative pressure to be taken from the intake passage and the predetermined value. | 10-30-2008 |
20080267789 | Control apparatus and control method for negative pressure generating apparatus - A control apparatus for a negative pressure generating apparatus, includes an ejector that generates a negative pressure whose magnitude is larger than that of a negative pressure to be taken from an intake passage in an intake system for an internal combustion engine provided in a vehicle; a state change device that makes the ejector function or stop functioning; and a prohibition control device that prohibits the state change device from making the ejector function, when the vehicle is transiently decelerated. | 10-30-2008 |
20090043477 | Ejector System for Vehicle - An ejector system controls the idle speed of an internal combustion engine by controlling an electric throttle valve system that adjusts the flow-rate of the intake air to be supplied to the internal combustion engine, and includes an ejector which generates a negative pressure of which the absolute value is larger than the absolute value of a negative pressure to be introduced from an intake manifold, a vacuum control valve which causes the ejector to operate or causes the ejector to stop operating, and an ECU that controls the vacuum switching valve. With the ejector system, even if the ejector is caused to operate or caused to stop operating, it is possible to appropriately suppress fluctuations in the idle speed, and appropriately obtain a negative pressure. | 02-12-2009 |
20100047081 | CONTROL APPARATUS AND CONTROL METHOD FOR NEGATIVE PRESSURE GENERATING APPARATUS - A control apparatus for a negative pressure generating apparatus that includes an ejector that generates a negative pressure whose magnitude is larger than that of a negative pressure to be taken from an intake passage in an intake system for an internal combustion engine provided in a vehicle; and state change means for making the ejector function or stop functioning. The control apparatus includes prohibition control means for prohibiting the state change means from making the ejector function, according to a temperature of intake air. | 02-25-2010 |
20120035829 | CONTROL DEVICE FOR INTERNAL COMBUSTION ENGINE - A control device for an internal combustion engine according to an embodiment includes: cooling units arranged on a path where a coolant is circulated, and cooling an exhaust gas of the internal combustion engine with the coolant flowing through the cooling units; a pump circulating the coolant; and ECUs estimating a heat quantity of the exhaust gas and deciding whether or not to operate the pump after an ignition switch is detected to be OFF in response to the estimated heat quantity of the exhaust gas. | 02-09-2012 |
20120035830 | CONTROL DEVICE FOR INTERNAL COMBUSTION ENGINE - A control device for an internal combustion engine according to the present embodiment, includes: cooling units | 02-09-2012 |
20120059566 | CONTROL DEVICE FOR INTERNAL COMBUSTION ENGINE - In a control device for an internal combustion engine according to the present embodiment, the control device includes: cooling units arranged on a path where a coolant is circulated, and cooling an exhaust gas of an engine with the coolant flowing through the cooling units; an atmospheric pressure sensor detecting an atmosphere pressure; and ECUs deciding whether or not to perform an exhaust gas temperature control for suppressing a temperature of the exhaust gas based on whether or not a heat quantity is more than a decision value, and correcting the decision value to be lower as the atmosphere pressure is lower. | 03-08-2012 |
20150125352 | AIR PURIFICATION APPARATUS FOR VEHICLE - An air purification apparatus for a vehicle, including a vehicle component provided at a location where air flows while the vehicle is moving, includes: an ozone decomposing body that contains MnO | 05-07-2015 |
