20120101708 | START-UP CONTROL SYSTEM FOR INTERNAL COMBUSTION ENGINE - An object is to provide a technology that enables starting of fuel injection under a condition that allows injected fuel to ignite and burn at the time of start-up of an internal combustion engine. To achieve the object, a start-up control system for an internal combustion engine according to the invention estimates, at the time of start-up of the internal combustion engine, the amount of rotation of a crankshaft in a period since the start of cranking until a crank position sensor outputs an effective pulse signal and determines, based on the stopping position of the crankshaft specified by the value thus estimated, whether or not fuel is to be injected at the first fuel injection time. | 04-26-2012 |

20130018548 | REGENERATIVE CONTROL SYSTEM FOR A VEHICLEAANM Shimasaki; YuichiAACI Mishima-shiAACO JPAAGP Shimasaki; Yuichi Mishima-shi JPAANM Futonagane; YoshinoriAACI Susono-shiAACO JPAAGP Futonagane; Yoshinori Susono-shi JPAANM Hirai; TakuyaAACI Susono-shiAACO JPAAGP Hirai; Takuya Susono-shi JP - The present invention is intended to suppress a change in a braking force due to a change in the magnitude of friction of an internal combustion engine, in a regenerative control system for a vehicle in which kinetic energy of wheels is made to be converted (regenerated) to electrical energy, at the time of deceleration running of the vehicle with the internal combustion engine mounted thereon. In order to solve this subject, the present invention is constructed such that the change in friction of the internal combustion engine is offset by adjustment of a regenerative braking force by regulating an amount of excitation current supplied to an electric generator according to the magnitude of friction in the internal combustion engine, at the time of deceleration running of the vehicle. | 01-17-2013 |
20130030647 | REGENERATION CONTROL SYSTEM FOR VEHICLE - An object of the invention is to increase the recovered kinetic energy as much as possible in a regeneration control system for a vehicle that converts the kinetic energy of a wheel into electrical energy while the vehicle is decelerating. To achieve the object, in the invention, the electric energy generated by a generator is decreased at the time when the wheel slips. In consequence, the recovered kinetic energy can be made larger as compared to the case where the electric energy generated by the generator is decreased based on an anticipation of slippage of the wheel made in advance. | 01-31-2013 |
20130042825 | LUBRICATION SYSTEM OF AN INTERNAL COMBUSTION ENGINE - The present invention is intended to reduce the friction of an internal combustion engine in a suitable manner when the internal combustion engine is in a cold state, thereby to attain the reduction of fuel consumption as well as the reduction of exhaust emission. In order to achieve this object, a lubrication system of an internal combustion engine of the present invention is provided with a generator which is capable of carrying out heat exchange with lubricating oil in the internal combustion engine, wherein an amount of electric power generated by the generator is increased when the temperature of the lubricating oil is lower than a target temperature. According to this lubrication system of an internal combustion engine, it becomes possible to quickly raise the temperature of the lubricating oil to the target temperature with the heat produced by the generator. | 02-21-2013 |
