摘要： In an engine having a premixed combustion mode, an EGR flow rate estimating precision is deteriorated at a transient time, and a torque fluctuation and an exhaust gas deterioration are caused. In an engine control apparatus having a premixed combustion mode and a diffusion combustion mode, a sensor detecting an EGR flow rate is arranged in an EGR flow path of the engine, and a cylinder state of the engine is estimated by using an output value of the sensor detecting the EGR flow rate at a time when the engine is in the premixed combustion mode. Since it is possible to accurately detect the EGR flow rate at the transient time and feed back the EGR flow rate at a high response, it is possible to prevent a torque fluctuation and an exhaust gas deterioration.

摘要： A main control computer commands a second sub-control computer to perform a reduced-cylinder operation when the coolant temperature detected by a coolant temperature sensor is greater than or equal to a reference temperature, and the exhaust temperature detected by a temperature sensor is less than a reference exhaust temperature and is within a reduced-cylinder operation allowable range in which a combination of the engine speed and the engine load is set in advance. The second sub-control computer deactivates a second cylinder group based on a command of the reduced-cylinder operation. The main control computer commands a first sub-control computer and the second sub-control computer to perform an all-cylinder operation when the coolant temperature detected by the coolant temperature sensor is less than the reference temperature, and the exhaust temperature detected by the temperature sensor is greater than or equal to the reference exhaust temperature or is out of the reduced-cylinder operation allowable range in which a combination of the engine speed and the engine load is set in advance.

摘要： A failure diagnostic device for an exhaust gas recirculation (EGR) apparatus, which can detect an intake pipe pressure at a high accuracy with a simple control and can prevent false diagnosis of an EGR system. If at least either one of first and second off-mode intake pipe pressures P1off, P2off exceeds a cancel determination value K, an ECU determines that the intake pipe pressures P1off, Pon and P2off are not properly detected, and cancels the failure diagnosis of the EGR system. Therefore, the false diagnosis of the EGR system can be avoided with a simplified process without requiring specific determinations on individual abnormal states of the various components other than the EGR system. By setting the cancel determination value K based on the intake pipe pressure P resulting when EGR off-control is executed in a state of an EGR valve being stuck in a fully-open position, each improperly-detected intake pipe pressure can be excluded with reliability.

摘要： A method of controlling a premix compression self-igniting internal combustion engine in which intake air and fuel are mixed in advance in a combustion chamber and the mixture is self-ignited by compression. Optimal self-ignition timing in accordance with operation condition can be obtained with the method for improved combustion. An exhaust valve (9) is temporarily reopened during a compression stroke, and timing of closing the reopened valve is variable, so that timing of the closure is varied for an effective compression ratio at which optimal self-igniting timing can be obtained at each operation region. A valve closure timing map for the exhaust valve reopening is formed from an engine speed and load, and closure timing of the exhaust valve (9) is varied based on the map. The closure timing of the exhaust valve (9) is varied such that an effective compression ratio is increased in an operation region where the load is small, and the ratio is reduced with an increase in the load.

摘要： In an NOx discharge quantity estimation method for an internal combustion engine equipped with an EGR apparatus, the gas components (e.g., oxygen molecules and NOx) of intake gas taken into a combustion chamber are assumed to be uniformly distributed throughout the entire region of the combustion chamber. Under such assumption, the combustion chamber is divided into a combustion region (region B) and a non-combustion region (region A) by making use of the ratio of the “mass of oxygen consumed as a result of combustion” to the “total mass of oxygen taken in the combustion chamber.” Further, under the assumption that NOx generated as a result of combustion remains in the region B after combustion, and NOx present in the region A before combustion due to circulation of EGR gas is conserved after combustion, the quantity of NOx discharged from the exhaust passage to the outside is calculated in consideration of not only the quantity of combustion-generated NOx in the region B but also the quantity of circulated NOx in the region A.

摘要： An exhaust particulate trapping means 12 for trapping particulates in exhaust gases is provided in an exhaust path 3 of an engine. When the engine enters a deceleration condition during the removal by burning of exhaust particulates trapped by the exhaust particulate trapping means 12, the drop of the flow rate of exhaust gases flowing into the exhaust particulate trapping means 12 is restricted. Thus, the cooling action of the exhaust particulate trapping means 12 through heat exchange with the exhaust gases can be kept up to suppress that the temperature of the exhaust particulate trapping means 12 excessively rises on engine deceleration.

摘要： A control device for a spark-ignition engine, in which a mixture in a combustion chamber is fired by compression ignition in a part-load range under warm-running conditions, includes an EGR controller incorporating a valve operation controller for controlling internal EGR of hot burned gas and a cold EGR controller for controlling external EGR of cold burned gas. The EGR controller performs EGR control operation to leave the hot EGR gas in the combustion chamber in a lower-load, lower-speed region within a compression ignition combustion range and to introduce the cold EGR gas into the combustion chamber in a higher-load, higher-speed region within the compression ignition combustion range. The control device further includes a firing assist unit for inducing the compression ignition at least when ignitability of the mixture decreases due to introduction of the cold EGR gas in the compression ignition combustion range.

摘要： An electronic valve actuation system and control method is described. The valve timing is changed between early and late intake valve closing depending on engine operating conditions. Further, valve timing is adjusted to control engine airflow or engine torque. Finally, air-fuel ratio is adjusted based on feedback from an exhaust gas oxygen sensor as well as an estimate of air, fuel, and residual exhausted from cylinders operating with late valve closing (after bottom dead center) timing.
