摘要： PROBLEM TO BE SOLVED: To prevent the air-fuel ratio from becoming lean due to sticking of fuel to a wall surface, when opening a throttle in response to an acceleration request, in an air-fuel ratio control device of an internal combustion engine.
SOLUTION: As a value of a purge correction factor FPG exists on the minus side, that is, as a purge correction of a fuel injection quantity is large, full open opening KTA of the throttle is restrained in a small value. An increase in a suction air flow rate is restrained by limiting the full open opening KTA, and reduction in the flow rate ratio between purge gas and suction air can also be relatively restrained. Thus, an increase in a fuel injection quantity can be restrained, in its turn, a shortage of wall surface sticking fuel can be restrained.

摘要翻译：要解决的问题：为了防止由于燃料粘附到壁面而导致的空燃比变得倾斜，当根据加速要求打开节气门时，在内燃机的空燃比控制装置中内燃机。解决方案：由于净负荷FPG的值存在于负侧，也就是说，随着燃料喷射量的清除校正量大，节气门的全开开度KTA被抑制在较小的值。通过限制全开口KTA来限制吸入空气流速的增加，也可以相对地抑制净化气体和吸入空气之间的流量比的降低。因此，可以抑制燃料喷射量的增加，从而可以抑制壁面粘附燃料的短缺。版权所有（C）2008，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To prevent abnormal combustion from occurring in a cylinder to which a purge gas is incompletely sucked in an evaporated fuel processing device for feeding an evaporated fuel to each of cylinders during the starting of the internal combustion engine.
SOLUTION: A crank angle sensor generating a cylinder discriminating signal when a #1 or #4 cylinder reaches its top dead center in intake stroke is installed in the evaporated fuel processing device. Based on the output of the crank angle sensor, a CCRNK indicating a crank angle is counted (Fig. (C)). After a cylinder discrimination is performed, ignition is performed in each of the cylinders in synchronism with the CCRNK, and a crank angle synchronous purge is performed for feeding an evaporated fuel to each of the cylinders (open arrow in Fig. (D)). The cylinder #2 capable of securing sufficient purge execution time in a period between the occurrence of the cylinder discriminating signal and the completion of the intake stroke is used as a crank angle synchronous purge start cylinder.

摘要： PROBLEM TO BE SOLVED: To improve the smoothness of an internal combustion engine when starting in an evaporated fuel processing device for feeding an evaporated fuel to each of cylinders at engine start. SOLUTION: A canister for accumulating the evaporated fuel is allowed to communicate with the intake port of each of the cylinders. A purge control valve for each of the cylinders is opened in synchronism with a crank angle after the starting of the internal combustion engine (open arrow in Fig. (D)). The position of a crank advanced by a purge advance angle amount from a crank angle at which an intake stroke is started in each of the cylinders is set to a purge start angle corresponding to each of the intake strokes. Purge advance angle amounts corresponding to an intake stroke at initial explosion performed together with an initial explosion (#3 cylinder) and an intake stroke immediately after initial explosion performed after that step are set larger than a purge advance angle amount corresponding to an intake stroke before initial explosion (#2 and #1 cylinders).

摘要： PROBLEM TO BE SOLVED: To stably realize such a state that, when a leakage failure occurs inside a device, an atmosphere outflow of an evaporated fuel is effectively prevented in a evaporated fuel processing device using the canister. SOLUTION: The canister is provided which adsorbs the evaporated fuel flowing from a fuel tank. A means for detecting a small leakage failure inside a system including the canister and the fuel tank, a means for introducing a negative pressure to the system, and a means for detecting tank internal pressure PTNK are provided. In a case where the leakage failure occurs (XEVP=1), when the PTNK is not more than an atmospheric pressure (PTNK>0 is not satisfied) (step 312), a CCV arranged to the atmosphere hole of the canister is opened to perform a normal purge (step 304, 306). When PTNK>0 is satisfied, the CCV is closed (step 316), to perform purge using a method capable of obtaining a large purge rate (step 314). COPYRIGHT: (C)2005,JPO&NCIPI
