20110146634 | SUPERCHARGER CONTROL DEVICE FOR AN INTERNAL COMBUSTION ENGINE - 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. | 06-23-2011 |
20110259290 | AMMONIA BURNING INTERNAL COMBUSTION ENGINE - 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. | 10-27-2011 |
20110264355 | CONTROL SYSTEM OF INTERNAL COMBUSTION ENGINE - 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. | 10-27-2011 |
20120285420 | CONTROL DEVICE FOR INTERNAL COMBUSTION ENGINE - A control device for an internal combustion engine includes: a variable valve timing portion changing a phase of opening and closing of each of an intake valve and an exhaust valve into a target phase; an EGR valve adjusting an exhaust gas recirculation amount recirculated from an exhaust side to an intake side; a supercharging efficiency control portion controlling a supercharging efficiency of a supercharger; a throttle valve adjusting an intake air amount; and the internal combustion engine feedback-controls at least two of the EGR valve, the supercharging efficiency control portion, and the throttle valve, and feedforward-controls the variable valve timing portion. | 11-15-2012 |
