| 20080307788 | Internal Combustion Engine with a Turbocharger - A multi-cylinder internal combustion engine including a plurality of banks and a turbocharger is oriented laterally within an engine compartment, wherein exhaust gas passages are connected to exhaust manifolds of each bank, a turbine of the turbocharger is installed in the exhaust gap passage of the bank positioned closest to the front side of the vehicle, and the turbocharger is disposed at a front position within the engine compartment. | 12-18-2008 |
| 20090000276 | Internal Combustion Engine and Method of Controlling the Same - Cylinders of an internal combustion engine are divided into at least two cylinder groups. First air-fuel ratio sensors are disposed in each exhaust branch pipe connected to the cylinder groups, and a second air-fuel ratio sensor is disposed in a common exhaust pipe upstream from the catalyst. When a vapor amount introduced into an intake passage during purge control is determined, the vapor amount is determined during normal operation using output values from the first air-fuel ratio sensors and the vapor amount value learned during normal operation. During rich-lean operation, the vapor amount is determined using the output value from the second air-fuel ratio sensor and the vapor amount value learned during rich-lean operation. Thereby, the vapor amount introduced into the intake passage when a switch is made from normal to rich-lean operation of the internal combustion engine is accurately determined. | 01-01-2009 |
| 20090138181 | Fuel Injection Control Apparatus and Control Method of Internal Combustion Engine - A fuel injection correction coefficient for a first fuel injection valve and a second fuel injection valve with respect to a second fuel injection proportion in a second combustion is learned (step | 05-28-2009 |
| 20090210138 | CONTROL DEVICE AND CONTROL METHOD FOR INTERNAL COMBUSTION ENGINE - A control device for an internal combustion engine includes a fuel injection device that injects a fuel in accordance with a required injection amount that is required for combustion in a combustion chamber that is performed to produce an output of the internal combustion engine, and a fuel property specific determination device that specifically determines a fuel property of the fuel injected. The control device further includes a control device that performs an output correction process of controlling at least a portion of the internal combustion engine so as to correct the produced output based on a difference in the specifically determined fuel property. According to the control device and a control method thereof, driveability is secured even in the case where a blended fuel is used during a high load region of the internal combustion engine. | 08-20-2009 |
| 20100011762 | INTERNAL COMBUSTION ENGINE AND CONTROL METHOD THEREOF - In a V-type six cylinder engine, cylinder groups are provided in which a plurality of cylinders are arranged divided into left and right first and second banks. An intake pipe, a first exhaust pipe, and a second exhaust pipe are connected to the cylinder groups of the banks. A first upstream three-way catalyst and a first control valve are provided in one exhaust pipe while a second upstream three-way catalyst and a second control valve are provided in the other exhaust pipe. The exhaust pipes are communicated together upstream of the upstream three-way catalysts and the control valves by a communicating pipe. A third control valve that adjusts the flowrate of exhaust gas is provided in the communicating pipe. | 01-21-2010 |
| 20100031941 | CONTROL DEVICE AND CONTROL METHOD FOR INTERNAL COMBUSTION ENGINE - A control device and control method for an internal combustion engine capable of using a gasoline and alcohol blend as fuel. The control device includes: an air-fuel ratio correction device that performs an air-fuel ratio feedback correction process calculating an air-fuel ratio feedback correction amount for compensating for a divergence between a target value and an actually measured value of an air-fuel ratio of the engine; an air-fuel ratio learning device that performs an air-fuel ratio learning process calculating an air-fuel ratio learned value for converging the calculated air-fuel ratio feedback correction amount into a predetermined range from a predetermined correction reference amount; and an alcohol determination device that makes an alcohol determination that a concentration of the alcohol blended is greater than a predetermined concentration if a deviation of the calculated air-fuel ratio learned value being greater than a predetermined threshold value continues longer than a predetermined period. | 02-11-2010 |
| 20100162686 | HYBRID VEHICLE AND METHOD FOR CONTROLLING SAME - A hybrid vehicle including an engine, a generator capable of generating power by being driven by the engine, an electric motor capable of running on power supplied from the generator, a power split device that transmits output from the engine to a driving wheel and the generator and also transmits output from the electric motor to the driving wheel, and a main ECU that controls an output ratio of the engine and an output ratio of the electric motor using the power split device according to the running state of the vehicle. When the operating mode of the engine is switched between a lean burn operating mode and a stoichiometric burn operating mode, the main ECU selectively increases and decreases the output ratio of the electric motor so that the total output, which is the combined output of the engine and the electric motor, is constant. | 07-01-2010 |
| 20100162689 | CONTROL DEVICE AND CONTROL METHOD FOR INTERNAL COMBUSTION ENGINE - In a region where the engine load is less than a first predetermined value, only a second exhaust valve that opens and closes a second exhaust passageway that bypasses a turbine of a supercharger is opened. In a region where the engine load is greater than or equal to the first predetermined value and less than a second predetermined value, both the second exhaust valve and a first exhaust valve that opens and closes a first exhaust passageway that leads to the turbine are opened. In a region where the engine load is greater than or equal to the second predetermined value, only the first exhaust valve is opened. A predetermined value for the time of lean combustion is set lower than a predetermined value for the time of stoichiometric combustion. | 07-01-2010 |
