摘要： PROBLEM TO BE SOLVED: To provide a clutch detection apparatus capable of inexpensively and precisely determining a disengagement/engagement condition of a clutch. SOLUTION: An inter-cylinder deviation Δω, a difference between a variation (first variation) ω0 of current and previous rotation numbers of a cylinder and a variation (second variation) ω1 of the current and previous rotation numbers of a cylinder for injecting fuel one cylinder before that cylinder, once changes in a minus direction, and then changes in a plus direction, in areas 100, 102 for shifting the clutch from a partial clutch engagement condition to a disengagement condition. The first variation ω0 is reduces together with the engine rotation number when it passes through the area 102 and the clutch is disengaged. The inter-cylinder deviation Δω changes in the minus direction together with the first variation ω0 in the area 120 when it passes through the area 102 and the clutch is disengaged, and then changes in the plus direction in the area 122 and becomes 0 almost constantly. The disengagement/engagement condition of the clutch is determined by comparing a difference between the inter-cylinder deviation Δω and the first variation ω0 with a predetermined value.

摘要： PROBLEM TO BE SOLVED: To provide an injection-quantity learning device for learning the injection quantity of a fuel in a wide pressure range in a short period of time.
SOLUTION: When there is an undetected high rail pressure for which the learning of fuel injection quantity is not completed, the learning of fuel injection quantity is performed according to the rail pressure for which the learning has been completed. In this case, the learning of the fuel injection quantity at the undetected rail pressure is performed by using the learned value of the fuel injection quantity learned at a rail pressure with increased correlation to the undetected rail pressure. Even when the chance of learning of a minute fuel injection quantity is less in the same way as when the pressure in a common rail is high, therefore, the change of the fuel injection quantity due to the change of the characteristic with time of the injector is learned. As a result, the error between an actually measured value and the learned value is reduced in the wide range of the rail pressure, and the fuel injection quantity is precisely controlled.

摘要翻译：要解决的问题：提供一种用于在短时间内学习在宽压力范围内的燃料的喷射量的喷射量学习装置。
解决方案：当燃料喷射量学习未被检测到的高轨道压力未完成时，根据完成学习的轨道压力来进行燃料喷射量的学习。在这种情况下，通过使用与未检测到的轨道压力相关性增加的轨道压力学习的燃料喷射量的学习值来进行未检测轨道压力下的燃料喷射量的学习。因此，即使在与共轨的压力相同的时候，与燃料喷射量相同的时候，燃料喷射量的学习时间较少，所以由于喷射器的特性随时间的变化而导致的燃料喷射量的变化被学习。结果，实际测量值和学习值之间的误差在轨道压力的宽范围内减小，并且燃料喷射量被精确地控制。版权所有（C）2009，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To provide a common rail type fuel injection system that prevents overshoot or undershoot when a pump discharge amount, pump pressure-feed amount, or fuel pressure in a common rail reaches target fuel pressure (PFIN), by preventing excessive correction of integral item upon abrupt change in PFIN.
SOLUTION: In a control logic, a feedback correction amount (IFB) as a correction item calculated from an IP control is added to a drive current value (IPMP) calculated based on an SCV drive current value calculation map by using such as a required discharge amount and actual fuel pressure to calculate final IPMP. When the PFIN is abruptly changed, the integral item is calculated from eccentricity of an actual fuel pressure from a second target fuel pressure excluding a target fuel pressure change amount, so that the integral item can be calculated only by a fuel pressure change component. Therefore, in the integral item, the target fuel pressure change component in never mistaken as a fuel pressure change component.

摘要： PURPOSE:To prevent dispersion caused by detection error of engine rotation so as to improve control accuracy by correcting a real value according to a difference between the real value and a demand value in relation to the spill angle of a spill valve when the injection amount of fuel fed under pressure by a pump is controlled by the spill valve. CONSTITUTION:Fuel is fed under pressure from a fuel injection pump A3 driven by diesel engine A1 while controlling an injection amount by a spill valve A2. At this time, the demand spill angle of the spill valve A2 is calculated by a demand spill angle calculating means A4. An engine rotational pulse is outputted from an engine rotation detecting means A5 per the constant crank angle of an engine. A count number from the reference position of the engine rotation pulse to a spill position and an angle which is less than 1 pulse are calculated by an angle time calculating means A6, and a remaining angle is reduced to a time. The spill valve A2 is controlled by a spill valve control means A7 on the basis of the count number and the remaining angle time. In this case, a real spill angle is corrected by a spill angle correcting means A8 according to the difference between the rear spill angle and the demand spill angle.
