摘要： PROBLEM TO BE SOLVED: To provide a fuel injection control device of an internal combustion engine achieving compatibility between a reduction in noises and NOx and a reduction in PM contained in discharge air.SOLUTION: The pressure of a fuel supplied to an injector 12 in pilot injection is set to be lower than the pressure of the fuel supplied to the injector 12 in main injection. Thus, the fuel jetted from the injector 12 in the pilot injection generates a thick mixture around the injector 12. Therefore, the ignitability of the fuel is improved even with a small amount of the pilot injection. On the other hand, in the main injection and after injection, the injector 12 jets the fuel at a pressure higher than that in the pilot injection. Therefore, the atomized fuel is supplied to a combustion chamber 18 that becomes high in pressure by the combustion of the fuel, and the combustion of the fuel is uniformized. Thus, the reduction in the noises and NOx and the reduction in the PM contained in the discharge air in the main injection and the after injection are achieved.
摘要翻译：要解决的问题：提供一种内燃机的燃料喷射控制装置，其实现噪声降低和NOx之间的兼容性以及排放空气中所含的PM的减少。解决方案：在先导喷射中供给到喷射器12的燃料的压力被设定为低于在主喷射中供给到喷射器12的燃料的压力。因此，在引燃喷射器中从喷射器12喷射的燃料在喷射器12周围产生浓稠的混合物。因此，即使少量的引燃喷射，燃料的点火性也提高。另一方面，在主喷射和喷射之后，喷射器12以高于先导喷射的压力喷射燃料。因此，通过燃料的燃烧将雾化的燃料供给到变成高压的燃烧室18，燃料的燃烧均匀化。因此，实现主喷射和后喷射中的排出空气中所含的噪声和NOx的降低以及PM的减少。版权所有（C）2013，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To provide a fuel injection control device for reducing smoke during emission, independently of operating conditions.SOLUTION: The fuel injection control device acquires a target value of a combustion parameter as a ratio of a cylinder oxygen amount to an after-injection amount at an ignition timing for after-injection (S402). The fuel injection control device calculates the ignition timing for the after-injection and a heat generation amount from a heat generation rate (S412, S414), and calculates a value (X_now) of an actual combustion parameter in the current combustion cycle from the cylinder oxygen amount and the after-injection amount calculated from a cylinder oxygen concentration at the ignition timing of the after-injection (S420). When a difference ΔX between a target value (X_target) of the combustion parameter and the actual value (X_now) of the combustion parameter is a predetermined threshold value or greater (S424:No), the fuel injection control device sets an after-injection amount and a main injection amount in the next combustion cycle for zeroing the difference ΔX to reduce smoke (S426, S428).

摘要： PROBLEM TO BE SOLVED: To provide an engine control apparatus, reducing burdens of conformance test work and map preparation work, avoiding degradation in controllability caused by mutual interference, and making engine output values get closer to request values even when controlled variables are restricted not to exceed a range of use.
SOLUTION: Correlation between a plurality of sorts of combustion parameters and a plurality of sorts of controlled variables is defined by a controlled variables arithmetic expression 32 to calculate combinations of command values of the plurality of sorts of controlled variables with respect to target values of the plurality of sorts of combustion parameters by the controlled variables arithmetic expression 32, so that the burden of conformance test work is reduced. Even if the command value of the controlled variables calculated by using the controlled variables arithmetic expression 32 is restricted to be an upper limit value or a lower limit value because the instruction value exceeds the range of use, other controlled variables not restricted are feedback-corrected to make the plurality of sorts of combustion parameters get closer to the target values, so that the engine output values are controlled to get closer to the request values.

摘要： PROBLEM TO BE SOLVED: To provide a fuel property detecting apparatus and a fuel property detecting method capable of improving the accuracy in detecting a cetane number of used fuel.
SOLUTION: In cetane number detection processing, when all of an operation index, an environment index and an intake index are satisfied (S140: YES), a pre-injection is performed with an initial setting quantity Qpf used as an injection quantity Qp and if a factor of non-generation exists, correction coefficient calculation processing is performed (S190). In the correction coefficient calculation processing, a temperature correction coefficient is acquired according to the factor of non-generation. When a factor of non-generation does not exist (or is eliminated), the injection quantity Qp is increased by a variation ΔQp (S180), torque sensitivity is derived according to a generated torque value acquired by a pre-injection at the increased injection quantity Qp and an increment of the injection quantity Qp at the pre-injection (S210), an estimated cetane number can is detected based on the derived torque sensitivity (S220) and then a cetane number with the estimated cetane number corrected is derived (S230).

摘要： PROBLEM TO BE SOLVED: To accelerate a smoke re-combustion effect while suppressing deterioration of combustion noise and to reduce a smoke generation amount.SOLUTION: A fuel injection control device includes a fuel injection valve for injecting fuel to an engine, and controls the fuel injection valve to perform at least main-injection and after-injection per combustion cycle. The fuel injection control device includes: a pressure transformer controlling an injection pressure of the fuel injected from the fuel injection valve; and a smoke sensor detecting a generation amount of smoke in the engine. An ECU controls the pressure transformer so as to start a combustion stroke at an injection pressure of a reference pressure value, to increase the injection pressure to an increased pressure value before the after-injection to the latest, and to perform the after-injection at the injection pressure of the increased pressure value. The ECU advances pressure-increase start timing of increasing the injection pressure on the basis of the smoke generation amount detected by the smoke sensor.

摘要： PROBLEM TO BE SOLVED: To provide an internal combustion engine with high response capable of reducing NOx contained in exhaust air without complicating a structure.SOLUTION: A variable valve mechanism control part 55 opens an exhaust valve 13 by a variable valve mechanism part 42 not only in an exhaust stroke, but also in a suction stroke. Thereby, exhaust air exhausted from a combustion chamber 16 is returned to the combustion chamber 16 together with suction air one part of which is sucked from a suction passage 28 in the suction stroke. A fluid injector 41 injects non-combustible fluid containing water to the exhaust air exhausted from the combustion chamber 16. Therefore, during the suction stroke, the exhaust air sucked in the combustion chamber 16 from an exhaust passage 23 contains water vapor generated by evaporating water in the non-combustible fluid. As a result, the exhaust air exhausted from the combustion chamber 16 in the exhaust stroke is added with the non-combustible fluid from the fluid injector 41, and returned to the combustion chamber 16 in the next suction stroke.

摘要： PROBLEM TO BE SOLVED: To provide an internal combustion engine reducing generation of PM (Particulate Matter) by lowering a temperature of mixture air formed by mixing fuel injected from a fuel injection valve and air and sufficiently securing ignition delay of injected fuel.SOLUTION: A liquid injection valve 13 injects water to fuel spray 60 formed by fuel injected from the fuel injection valve 12 in a combustion chamber 18. By injecting water to the fuel spray 60, the fuel spray 60 is cooled by the injected water. Accordingly, a temperature rise of combustion gas generated by combustion of fuel is suppressed.

摘要： PROBLEM TO BE SOLVED: To provide a fuel injection control device of an engine, which controls a combustion state to a desired state more easily and precisely without depending on an adaptation map or detecting a cylinder pressure, and also to provide combustion equipment of an engine that is useful for monitoring or controlling the combustion state. SOLUTION: When controlling fuel injection of a target engine (engine 10), prior to execution of main injection for mainly generating output torque in a combustion cycle, pilot injection (preliminary sub-injection) where an injection amount is smaller than that of the main injection is executed. The fuel injection control device of the engine (engine-control ECU 80) is configured to include a program of setting the injection amount of the pilot injection variable according to the temperature of exhaust gas discharged after combustion in the engine 10. More particularly, the pilot injection amount is corrected and controlled to a target value on a larger side as the exhaust gas temperature is higher. COPYRIGHT: (C)2008,JPO&INPIT
