Abstract: A supercharger control device for an internal combustion engine is preferably applied to a system having a first supercharger and a second supercharger. A switching supercharging pressure setting unit sets a switching supercharging pressure used in case of switching a mode for operating the first supercharger and the second supercharger, based on a difference between a target supercharging pressure and an actual supercharging pressure. When the actual supercharging pressure reaches the switching supercharging pressure, a switching control unit performs a control of switching the mode. Therefore, it becomes possible to appropriately prevent the overshoot of the supercharging pressure at the time of switching the mode.

Abstract: A control apparatus for an internal combustion engine is provided which can accurately correct a valve timing deviation of an intake valve caused by a variable operating angle mechanism or variable phase mechanism.A variable operating angle mechanism (28a) for making the operating angle of an intake valve (24) variable is provided. Operating angle command values (operating angles 1 and 3) of two points in front and back at which the intake air amount is decreased by a predetermined amount with respect to the value that is judged to be a maximum value of the intake air amount when the operating angle (command value) is kept changing, are acquired. Then, an intermediate value which is at an equal distance from the operating angle command values of the two points is calculated as the maximum operating angle command value. Then, this maximum operating angle command value is compared with a reference characteristic to execute the calculation of the deviation amount of the valve timing and the correction of the deviation.

Abstract: An ammonia burning internal combustion engine can feed ammonia and a highly combustible substance burning easier than ammonia to a combustion chamber. When the amount of ammonia fed into the combustion chamber is increased or when the ratio of the amount of the ammonia to the total amount of the ammonia and the highly combustible substance fed into the combustion chamber is increased, the operating parameters of the internal combustion engine are controlled so the air-fuel mixture fed into the combustion chamber is made easier to burn. As a result, an ammonia burning internal combustion engine designed to suppress a drop in combustibility of auxiliary fuel due to ammonia, can be provided.

Abstract: A first and a second superchargers are arranged in parallel with each other on an intake air passage and an exhaust passage. At least one of the first and the second superchargers includes a variable supercharging mechanism. The control unit determines a target air amount ratio of the first and the second superchargers, and controls the variable supercharging mechanism such that an actual air amount ratio of the first and the second superchargers becomes equal to the target air amount ratio. The air amount ratio which does not cause the surge in the first and the second superchargers is set as the target air amount ratio, and the variable supercharging mechanism is controlled by using it as a target.

Abstract: An internal combustion engine can use ammonia and a non-ammonia fuel which is easier to burn than ammonia as fuel. The non-ammonia fuel is directly injected into a combustion chamber by a non-ammonia fuel injector, and the injected non-ammonia fuel is ignited, whereby combustion of the air-fuel mixture in the combustion chamber is commenced. In the control system of the internal combustion engine, the injection timing of the non-ammonia fuel is advanced at a time when a ratio of ammonia in all fuel fed to the internal combustion engine is high in comparison with the time when the ratio is low. Therefore, a control system of an internal combustion engine capable of using ammonia and a non-ammonia fuel (gasoline, light oil, hydrogen, etc.) which is easier to burn than ammonia, which suitably feeds fuel and controls combustion in order to suitably burn an air-fuel mixture in a combustion chamber is provided.
