Abstract: To optimize fuel supply of an engine with a carburetor during engine operation, a throttle opening degree detection sensor detecting a throttle opening degree and a control unit controlling a valve body variably controlling an opening degree of a fuel discharge part or a fuel supply passage based on a map are included. The map includes a plurality of sections divided based on the throttle opening degree and an opening degree of the valve body set for each section. The opening degree of the valve body set for each section is the opening degree of the valve body at which the engine rotation speed is highest in each section. The control unit controls an electric actuator driving the valve body to achieve the opening degree of the valve body set in a section to which the throttle opening degree detected by the throttle opening degree detection sensor belongs out of the plurality of sections.

Abstract: An engine assembly includes an engine with an engine block having at least one cylinder. A crankshaft is moveable to define a plurality of crank angles from a bore axis defined by the cylinder to a crank axis defined by the crankshaft. The plurality of angles includes a crank angle (CA50) corresponding to 50% of the fuel received by the cylinder being combusted. A controller is operatively connected to the engine and has a processor and a tangible, non-transitory memory on which is recorded instructions for executing a method for controlling the combustion phasing in the engine during a transient state. The controller is programmed to generate a learned table by storing at least one combustion phasing parameter in the tangible, non-transitory memory. Combustion phasing during a transient state is controlled based at least partially on the learned table.

Abstract: A fuel injection control device learns a port injection learning value and a direct injection learning value separately for each of learning regions that are divided according to the engine operating state. It is assumed that a port injection learning condition and a direct injection learning condition are both satisfied in a learning region in which neither the learning of the port injection learning value nor the learning of the direct injection learning value has been completed. In such a situation, the fuel injection control device executes the port injection learning process if the ratio of the port injection amount is less than the ratio of the direct injection amount, and executes the direct injection learning process if the ratio of the direct injection amount is less than the ratio of the port injection amount.

Abstract: A control device for a compression ratio variable internal combustion engine is provided with a compression ratio variable mechanism for changing an engine compression ratio in accordance with a rotational position of a control shaft, and a detection unit that detects an actual compression ratio. In a predetermined engine operating condition such as immediately after an engine start, reference position learning operation for the detection unit is carried out with the control shaft mechanically locked up at a predetermined reference position. During operation of the engine, even when the actual compression ratio is lost or a difference between the actual compression ratio and a target compression ratio becomes greater than an assumed deviation, due to some abnormalities, the reference position learning operation is immediately carried out, thereby enabling a quick return to a state where normal compression ratio control can be carried out.

Abstract: A control apparatus for an internal combustion engine having a throttle valve disposed in an intake passage of the engine is provided. A wide-open intake air amount, which is an intake air amount corresponding to a state where the throttle valve is fully opened, is calculated, and a theoretical intake air amount, which is an intake air amount corresponding to a state where no exhaust gas of the engine is recirculated to a combustion chamber of the engine, is calculated according to the wide-open intake air amount and the intake pressure. An air-fuel ratio correction amount and a learning value thereof are calculated according to the detected air-fuel ratio, and a reference intake air amount is calculated using the intake pressure, the engine rotational speed, the air-fuel ratio correction amount, and the learning value. A lower limit value of the detected intake air amount is set according to the reference intake air amount, and a limit process is performed for limiting the detected intake air amount within a range of values which are equal to or greater than the lower limit value. An amount of the evaporative fuel/air mixture supplied to the intake passage is calculated, and the limit-processed intake air amount is corrected using the evaporative fuel/air mixture amount to calculate an intake gas amount. An exhaust gas recirculation ratio is calculated using the theoretical intake air amount and the intake gas amount.

Abstract: Upon satisfaction of an idle learning condition, the internal combustion engine system of the invention successively performs learning of an idle control amount and learning of a most delayed angle control amount in this sequence. Upon satisfaction of a most delayed angle learning condition, on the other hand, the internal combustion engine system successively performs learning of the most delayed angle control amount and learning of the idle control amount in this sequence. This arrangement effectively reduces the total time required for completion of learning both the idle control amount and the most delayed angle control amount, compared with the conventional procedure of individually learning only one control amount corresponding to the satisfied learning condition.
