20100305833 | FUEL INJECTION CONTROL APPARATUS OF INTERNAL COMBUSTION ENGINE - In one embodiment, a determination is made of whether or not in a condition in which a compressed gas temperature will reach a fuel self-ignition temperature by only a compression operation in the compression stroke, and in a case where the compressed gas temperature will reach the fuel self-ignition temperature, pilot injection is judged to be unnecessary, so this pilot injection is prohibited. | 12-02-2010 |
20110005491 | FUEL INJECTION CONTROL APPARATUS OF INTERNAL COMBUSTION ENGINE - In one embodiment, a total pilot injection amount is calculated from the difference between a compressed gas temperature in a cylinder and a fuel self-ignition temperature. As pilot injection, a plurality of instances of divided pilot injection are performed, and by setting the injection amount per one instance of divided pilot injection to an injector minimum limit injection amount, each divided pilot injection amount is suppressed, and the penetration of fuel is suppressed to a low level so that attachment of fuel to a wall face is avoided, and also, fuel is caused to accumulate in the center portion of the cylinder. | 01-13-2011 |

In a common rail diesel engine capable of executing at least a main injection and a pre-injection as an operation of fuel injection from an injector, the pre-injection is executed by being split into a first pre-injection and a second pre-injection. The injection timing and the injection amount of each fuel injection is controlled such that some of the fuel injected in the first pre-injection combusts by self-ignition, and the remainder of the fuel does not combust until fuel is injected in the main injection, but combusts together with the fuel injected in the main injection. Also, the injection timing of each fuel injection is controlled such that the fuel injected in the first pre-injection and flowing along a swirl flow in the cylinder overlaps the fuel injected in the subsequent main injection. | 03-10-2011 |
20110060514 | FUEL INJECTION CONTROL APPARATUS OF INTERNAL COMBUSTION ENGINE - A fuel injection control apparatus of an internal combustion engine of the present invention performs control for a common rail diesel engine so that at a timing when a piston reaches compression top dead center, the rate of heat production due to the combustion of fuel injected in pre-injection is substantially maximal, and furthermore so that the combustion of fuel injected in main injection is started in the vicinity of this timing. As a result, the combustion of fuel injected in main injection is started by fully utilizing the heat production amount due to the pre-injection. Also, this avoids the production of reverse torque, as well as ensures maximizing the amount of torque produced by the combustion of fuel injected in main injection. | 03-10-2011 |
20110180039 | FUEL INJECTION CONTROL APPARATUS FOR INTERNAL COMBUSTION ENGINE - In a common rail diesel engine, main injection is executed as injection divided into first divided main injection and second divided main injection. In the first divided main injection, fuel injection is stopped before a fuel evaporation speed in a combustion field becomes greater than an oxygen supply speed. After fuel injection is temporarily stopped, the combustion field of fuel that was injected in the first divided main injection flows in a circumferential direction within a combustion chamber according to a swirl flow, and the second divided main injection is executed when a region where the fuel evaporation speed is less than the oxygen supply speed, this being a region between combustion fields, has moved to a position facing an injection nozzle. | 07-28-2011 |
20120016571 | CONTROL APPARATUS OF INTERNAL COMBUSTION ENGINE - A series of combustion forms including initial low-temperature combustion, premixed combustion, and diffusive combustion are performed when an engine operates under a low load and a medium load. The initial low-temperature combustion is carried out by performing a small-amount injection while performing an operation for lowering the encounter rate between oxygen and a fuel spray in a cylinder, and thereby the heat generation rate is kept low and the amount of NOx generated is suppressed. The premixed combustion is carried out as fuel receives heat in the initial low-temperature combustion, and the amount of smoke generated is suppressed. The diffusive combustion is accomplished as fuel travels through the combustion field of the premixed combustion, and by controlling the fuel injection timing thereof, it is possible to suitably control the timing at which the heat generation rate reaches its maximum in the aforementioned series of combustion. Thereby, it is possible to concurrently suppress the amount of NOx generated, suppress the amount of smoke generated, and secure the required torque. | 01-19-2012 |
20120143479 | COMBUSTION CONTROL APPARATUS OF INTERNAL COMBUSTION ENGINE - During high-load operation of an engine, fuel for initial slow-burning combustion and premixed combustion is injected into a combustion chamber by continuous fuel injection, then fuel injection is paused, and fuel for diffusion combustion is injected after a predetermined interval has elapsed. Also, the fuel injection amount in the continuous fuel injection is set higher than the fuel injection amount for diffusion combustion. A spray autointerference cooling effect is achieved by the continuous fuel injection, thus promoting ignition delay so as to increase the proportion of premixed combustion, thereby suppressing the production of smoke. This enables high-volume EGR to be performed, thus enabling reducing the amount of NOx produced. | 06-07-2012 |
20120253640 | FUEL INJECTION CONTROL APPARATUS OF INTERNAL COMBUSTION ENGINE - An auxiliary injection is carried out at an in-cylinder temperature at which a premixed combustion by the auxiliary injection is separatable into a low-temperature oxidation reaction and a high-temperature oxidation reaction, in a compression self-igniting internal combustion engine in which fuel injected into a cylinder from a fuel injection valve combusts in the cylinder, and that is configured to carry out an operation of fuel injection from the fuel injection valve. The operation of fuel injection includes at least a main injection and the auxiliary injection. The main injection causes a combustion mainly including a diffusion combustion in the cylinder. The auxiliary injection is carried out prior to the main injection and causes a combustion mainly including the premixed combustion in the cylinder. Specifically, an in-cylinder gas temperature (750K) is used as a reference, and the auxiliary injection is carried out before the in-cylinder gas temperature reaches 750K, so as to separate the low-temperature oxidation reaction and the high-temperature oxidation reaction from one another. This control makes the premixed combustion slow before a compression top dead center is reached, and ensures control of the premixed combustion in a temperature controlled manner in accordance with the transition of the in-cylinder gas temperature. This ensures unambiguous determination of the injection time of the auxiliary injection based on the in-cylinder temperature, and facilitates the attempt to simplify the fuel injection control. | 10-04-2012 |
20130024097 | COMBUSTION CONTROL APPARATUS FOR INTERNAL COMBUSTION ENGINE - In an internal combustion engine (engine) in which premixed combustion and diffusion combustion are carried out in a combustion chamber, the premixed combustion and the diffusion combustion are separated by carrying out a control to limit the minimum value of the heat generation rate between the combustion centroid of the premixed combustion and the combustion centroid of the diffusion combustion, or carrying out a control to adjust the interval between a first injection for the premixed combustion and a second injection for the diffusion combustion. In this manner, the combustion form in the combustion chamber is made separated combustion in which the premixed combustion and the diffusion combustion are separated, and therefore ignition delay in the earlier premixed combustion does not influence the later diffusion combustion, thus making it possible to use the respective advantages of the premixed combustion and the diffusion combustion. Accordingly, it is possible to achieve a reduction of emissions and combustion stability also during a transient operation or during use of fuel that has a low cetane rating. | 01-24-2013 |
20160053702 | HEAT RELEASE RATE WAVEFORM GENERATING DEVICE AND COMBUSTION STATE DIAGNOSTIC SYSTEM FOR INTERNAL COMBUSTION ENGINE - In a diesel engine, an inside of a cylinder is divided into intra-cavity and extra-cavity regions. Ideal heat release rate waveform models, each formed of an isosceles triangle in which each oblique line gradient is a reaction rate, an area is a reaction amount and a base length is a reaction period with a reaction start temperature as a base point, are generated respectively for a vaporization reaction, low-temperature oxidation reaction, thermal decomposition reaction and high-temperature oxidation reaction of injected fuel for each region. An ideal heat release rate waveform of the reaction modes is generated by smoothing the ideal heat release rate waveform models through filtering and combining the ideal heat release rate waveforms, and is compared with an actual heat release rate waveform obtained from a detected in-cylinder pressure. A reaction mode having a deviation larger than or equal to a predetermined amount is diagnosed as being abnormal. | 02-25-2016 |
