20100192883 | VARIABLE VALVE APPARATUS - A first overlap amount that is an overlap amount of overlap between an intake valve opening timing and an exhaust valve opening timing, is calculated based on rotation speed of an internal combustion engine, load on the engine, and temperature of a working fluid.

20100222986 | CONTROL DEVICE FOR INTERNAL COMBUSTION ENGINE - An exhaust valve early-closure control brings about blowback of exhaust gas into an intake system. However, if the exhaust valve early-closure control is executed, for example, during a first idle operation immediately following the startup of the engine, or the like, the amount of blowback exhaust gas becomes excessively large. Therefore, when the post-startup increase amount has decreased to or below a lower-limit criterion value, the ECU prohibits the exhaust valve early-closure control, and changes the control to a usual valve timing control. As a result, during a period during which the combustion state has a stability margin and the amount of emission of HCs and the like is large, the exhaust emission quality can be bettered by the exhaust valve early-closure control. Besides, when the post-startup increase amount has decreased, the combustion state can be stabilized by prohibiting the exhaust valve early-closure control. | 09-02-2010 |
20110192380 | CONTROL DEVICE OF INTERNAL COMBUSTION ENGINE - An internal combustion engine is provided with a fuel injector which injects fuel into an intake port and exhaust variable valve timing mechanism which changes a valve timing of an exhaust valve. A control device executes early exhaust valve closing control which advances a closing timing of an exhaust valve when conditions for executing early exhaust valve closing control stand. The control device includes a torque detecting means which detects an output torque output by an engine body. At the time of deceleration of the engine, even when the condition for executing early exhaust valve closing control stands, execution of early exhaust valve closing control is prohibited when it is predicted that the output torque will become smaller than the limit torque. Thus, due to execution of the early exhaust valve closing control, a large torque fluctuation is prevented from occurring at the time of deceleration of the engine. | 08-11-2011 |

20130338904 | AIR-FUEL RATIO CONTROL APPARATUS FOR AN INTERNAL COMBUSTION ENGINE - An air-fuel ratio control apparatus for an internal combustion engine of the present invention determines whether or not a lean request has occurred, based on a comparison between a value correlating with an output value of the downstream air-fuel ratio sensor disposed downstream of the catalyst (downstream air-fuel ratio sensor output correlating value) and a predetermined lean request determining value, and determines whether or not a rich request has occurred, based on a comparison between the downstream air-fuel ratio sensor output correlating value and a predetermined rich request determining value. Further, the air-fuel ratio control apparatus calculates a total amount of oxygen (released oxygen amount) released from the catalyst in the rich request occurring period, and calculates an integrated value (present stored oxygen amount) of oxygen stored in the catalyst after a start of the lean request occurring period which follows the rich request occurring period. The apparatus changes the rich request determining value in such a manner that a point in time at which it is determined that the rich request has occurred comes much earlier as the present stored oxygen amount comes closer to the released oxygen amount. | 12-19-2013 |

The ECU sets a distribution ratio of the first fuel injection valve to 100% when an accumulation amount Spfi is larger than a predetermined value Xpfi in a predetermined case. The predetermined case is a case where the valve actuating device closes the exhaust valve on an advance side with respect to an exhaust top dead center and a state where a minus overlap is formed between the intake valve and the exhaust valve is established and a case where the distribution ratio of the second fuel injection valve is set to 100%. | 11-13-2014 |

20150337744 | CONTROL DEVICE FOR INTERNAL COMBUSTION ENGINE - An object of this invention is to appropriately control valve timings based on a fuel property and an engine temperature to improve exhaust emissions. An engine is equipped with a function that drives variable valve mechanisms to execute intake valve retarded-opening control and exhaust valve early-closing control. An ECU variably sets a low-temperature determination value based on an alcohol concentration in a fuel. If a water temperature of the engine is equal to or less than the low-temperature determination value, the ECU prohibits the intake valve retarded-opening control and permits the exhaust valve early-closing control. Consequently, during cold operation it is possible to avoid a deterioration in combustion properties (deterioration in in-cylinder turbulence) caused by intake valve control and thereby suppress a deterioration in exhaust emissions. Further, because exhaust valve control is permitted, for example, a negative overlap period that satisfies a control request can be secured by advancing the closing timing of the exhaust valve. Accordingly, exhaust emissions and catalyst warm-up performance can be improved. | 11-26-2015 |
20150343379 | ATMOSPHERE-CLEANING DEVICE FOR VEHICLES - An object of this invention is to provide an atmosphere-cleaning device for vehicles that is capable of restoring the function of an ozone purifying body carried by a vehicle component. Mud, dust, snow-melting agents as well as SOx and NOx are scattered into the atmosphere as a result of being swirled up by a preceding vehicle or due to weather and climate conditions. When such extraneous substances adhere or the like to an ozone purifying body, the purification sites thereof are clogged and the ozone purification function deteriorates. Therefore, when a predetermined removal implementation condition is established, control is executed to inject cleaning liquid from an injector to enhance the fluidity of the extraneous substances and wash the extraneous substances away. The function of the ozone purifying body can thereby be restored. | 12-03-2015 |
