Title: Fuel oil feed rate control type fuel injection pump
Inventor: ISHII MUTSUNORI
IPC: F02M41/12
Filed: 1991-05-17
Abstract: PURPOSE:To decrease the fuel oil feed rate in the light load range so as to reduce the discharge of exhaust contaminated gas by fitting dual sprue rings of a plunger of a distributor type fuel injection pump, and forming a leak port where a throttle is formed on the plunger. CONSTITUTION:A fuel passage 2 is bored in the shaft center of a plunger 1, and a spill port 6 is formed in a designated position of the rear portion of the plunger 1. Leak ports 9 right-angled to the fuel passage 2 and the spill port 6 are bored in designated positions in the rear of the spill port 6, and an orifice 11 is interposed between the leak port 9 and the fuel passage 2. Two sprue rings 13, 14 externally fitted to the plunger 1 are positioned in such a manner that the gap W between both rings intervenes between the spill port 6 and the leak port 9. Thus, in the comparatively initial injection timing during the whole injection time in the light load case, injection with low oil feed rate is performed so as to the generation of exhaust contaminated gas due to excess fuel injection.

Filed: 1999-04-21
Abstract: PROBLEM TO BE SOLVED: To obtain an error correcting encoding apparatus which can generate encoded data without executing error correcting encoding again even when a recording point is shifted to a succeeding area because of a recording error or the like in a recording system to recording media required to operate in real time. SOLUTION: A data error detection code is added to inputted data, which is stored in a first memory means 102. A parity is generated by a first parity generation means 103. The data are thus error-corrected and encoded. Meanwhile, pattern data determined uniquely to an inputted data ID are generated, error-corrected and encoded and stored in a second memory means 105. The error corrected encoded data in the first memory means 102 and error-corrected encoded pattern data in the second memory means 105 are added by an adding means 107, whereby encoded data are outputted.
