Title: Method and device for determining stroke of four-cycle internal combustion engine
Inventor: SHIMOYAMA AKIRA
IPC: F02D45/00
Filed: 2002-04-16
Abstract: PROBLEM TO BE SOLVED: To provide a stroke determining method which can judge a stroke of a four-cycle internal combustion engine, without using a camshaft sensor. SOLUTION: A section of one rotation, starting from when a piston of a cylinder of the four-cycle internal combustion engine 1 reaches the position of the top dead center until when it reaches there again, is regarded as a target section for determination. The output of a pressure sensor 12 for detecting intake pressure of the internal combustion engine which reflects a change of stroke performed by the engine cylinder 1a is sampled at certain sampling intervals. The maximum value of inclination of change of the intake pressure in the process, in which the absolute value of the intake pressure sampled in each determination target section increases, is obtained as a determination target value.  When the determination target value obtained in each determination target section is larger than the same obtained in the determination target section once prior to each determination target section, each determination target section is judged to be a section in which a suction stroke and a compression stroke are performed.

The specific time is between 0.3 sec and 1 sec. hereafter, the specific time is represented by T. Next, when inputting the second column of each of rows, after each of number keys is pressed within the time T and released, the same key is pressed and released again so that the character input of the second column can be determined.  Besides, when inputting a KANA character after the third column of each of rows, after each of number keys is pressed and released within the time T and a combined key assigned individually for inputting the character after the third column to be pressed secondly is pressed and released again so that the character input after the third column can be determined. In such a case, this means has a function capable of KANJI conversion even after the KANA character input is determined.
