Model-Based Development Design for a Continuously Variable Discharge Oil Pump Design 2019-01-0764

Recently, for protection of the environment, the regulation of automobile fuel consumption and exhaust gas emission has been strengthened. In light of such circumstances, automobile parts are generally required to be able to improve fuel efficiency and reduce exhaust gas emission.
In order to meet such requirements, the structure of fuel/exhaust-related devices has become complicated. Redesigns of future products that will be increasingly complex will lengthen the development period and reduce cost efficiency seriously. However, since it has been difficult to find, the best design parameters that satisfy the following two important design elements, we have been forced to meet requirements by redesign of the oil pump.
  1. i
    Size of oil pressure change (when this is variable)
  2. ii
    Speed of change of oil pressure in response to variable control operation
In order to meet such requirements more easily, we commenced construction of an original one dimensional (1D) Model-Based Development (MBD) tool to carry out unsteady calculation in our design process. As a result, we further were able to configure an original MBD tool that can solve nonlinear stiff ordinary differential equations at high speeds. In this article, we are introducing our original MBD tool with actual case examples.
