| Abstract: | The radial tolerance clearance of the precise fitting pieces assembly in electronically controlled high pressure common rail fuel injection system for diesel engines will affect the performance and life of the injection system comparatively greatly,nevertheless the tolerance clearance was chosen only by experience ever before. In this paper, based on the fluid theory of laminar flow in slit flow way,the formula of optimal radial clearance was established from the viewpoint of the least sum of fluid leakage and viscous friction energy consumption. The formula put forward in this paper is rational and can be consulted in engineering application according to the calculated results. |
