Analysis of By-Pass Control Type Fuel Injection System for Small Diesel Engine by Digital Computer : Part 1, Theoretical Analysis and Calculation Method

概要

Until now, theoretical analyses using a digital computer have been inadequate. In this report, the following improvements were added to the conventional theoretical analyses: (1) Until the present, conventional analyses were carried out using for the most part an overflow type pump, a high pressure fuel pipe and a fuel nozzle. In this report, however, analysis was made using a by-pass control type pump (considered to be the basic structure of any pump system), a high pressure fuel pipe, a fuel nozzle, a fuel tank, a fuel feed pipe and fuel feed chamber. (2) In conventional analyses, when a void appeared in the fuel injection system, it was necessary to substitute a different equation and the boundary conditions of both ends of the high pressure fuel pipe were believed to be unsatisfactory. We have tried to improve on these points.
