20110098905 | CONTROL DEVICE FOR INTERNAL COMBUSTION ENGINE - Disclosed are a control device and a control method that are used with an internal combustion engine in which the air-fuel ratio in the vicinity of an ignition plug differs from the overall air-fuel ratio in a cylinder, and capable of properly fulfilling demands concerning various capabilities of the internal combustion engine by accurately reflecting each of the demands in the operation of each actuator. Three physical quantities, namely, a torque, an efficiency, and an air-fuel ratio, are used as controlled variables for the internal combustion engine. Target values for the controlled variables are then set by integrating at least some of demands concerning a capability of the internal combustion engine into the three physical quantities. Further, in accordance with the target values for the three controlled variables, namely, the torque, the efficiency, and the air-fuel ratio, three operation amounts, namely, an intake air amount adjustment valve opening, an ignition timing, and a fuel injection amount are set, and a fourth operation amount for adjusting the air-fuel ratio distribution in the cylinder is set. | 04-28-2011 |
20120185148 | CONTROL DEVICE FOR INTERNAL COMBUSTION ENGINE - Disclosed is a control device that is used for an internal combustion engine and capable of making various requests concerning the performance of the internal combustion engine be reflected in a target control amount value while the requests need not be expressed in the form of a requested control amount value. The control device acquires various requests concerning the performance of the internal combustion engine and sets a request-specific constraint on a control amount value. More specifically, the control device expresses constraints to be set for control amount values as a set of constraint index values assigned to individual control amount values, and varies the distribution of the constraint index values assigned to the control amount values in accordance with the type of a request. Next, the control device integrates, for each control amount value, the constraint index values assigned to individual requests with respect to each control amount value. Then, in accordance with the distribution of the integrated constraint index value for a control amount, the control device determines a limitation of the control amount, which is defined by an upper-limit value and a lower-limit value. The control device determines a target control amount value within the determined limitation. | 07-19-2012 |
20120204629 | EXHAUST CATALYST TEMPERATURE ESTIMATING APPARATUS AND EXHAUST CATALYST TEMPERATURE ESTIMATION METHOD FOR INTERNAL COMBUSTION ENGINE - A exhaust catalyst temperature estimating apparatus is provided for estimating a exhaust catalyst temperature of a exhaust catalyst in which a catalyst is loaded on a support and arranged in an exhaust system of an internal combustion engine. The exhaust catalyst temperature estimating apparatus estimates the exhaust catalyst temperature using a first model formula to calculate a current exhaust catalyst temperature of the exhaust catalyst based on a parameter corresponding to a current exhaust gas status. The first model formula is empirically determined such that a exhaust catalyst temperature that excludes heat generated by a chemical reaction is calculated for the parameter by using the support prior to being loaded with the catalyst, or is a physical formula of the support prior to being loaded with the catalyst such that a exhaust catalyst temperature excludes heat generated by a chemical reaction is calculated for the parameter. | 08-16-2012 |
20120316750 | CONTROL APPARATUS FOR INTERNAL COMBUSTION ENGINE - A control apparatus of an internal combustion engine capable of appropriately reflecting various requests relating to the performance of the internal combustion engine. Specifically, the control device of the internal combustion engine acquires various requests relating to the performance of the internal combustion engine, and sets restricted ranges of the value of the control variable in accordance with the details of the requests. At this moment, the control device temporally changes the set restricted ranges for specific requests associated with the time integral value of the control variable rather than the instantaneous value of the control variable. Subsequently, the control device determines a final restricted range on the basis of the overlap between the restricted ranges set for each request, and determines the target value of the control variable in the final restricted range. | 12-13-2012 |

20090287396 | FUEL PROPERTY DETERMINATION SYSTEM, AND FUEL PROPERTY DETERMINATION METHOD FOR INTERNAL COMBUSTION ENGINE - The fuel injection amounts into each cylinder are set on the assumption that a heavy fuel will be injected during the engine starting process, and a specific torque is allowed to be generated by combustion in a specific cylinder when a fuel with a specific property between those of the heaviest fuel and the lightest fuel is injected thereinto. When the torque generated in the specific cylinder is in a range at or around the specific torque, the property level of fuel to be injected during the engine starting process is determined to be in a level range at or around the specific property. When the torque generated in the specific cylinder is higher than the range around the specific torque, the property level is determined to be in a level range on the light fuel side of the level range around the specific property. | 11-19-2009 |

20100319659 | CONTROL DEVICE FOR INTERNAL COMBUSTION ENGINE - A control device for an internal combustion engine which, at cold starting, enables an ignition timing retard control for warm-up of a catalyst device and a speed feedback control by means of ignition timing for converging an engine speed to a target speed includes a function for comparing a final ignition timing with a retard lower limit value, and a function for changing the target speed based upon the result of the comparing. When the final ignition timing reaches the retard lower limit value, the target speed is increased by a predetermined speed and when a difference between the final ignition timing and the retard lower limit value exceeds a predetermined angle on an advance side, the target speed is decreased by a predetermined speed. In this way, at cold starting, the engine speed is early converged to the target speed while restricting rotational variations and early warm-up of a catalyst device can be certainly realized. | 12-23-2010 |
