Abstract: The invention relates to a fuel injection system of the common rail type having a rail body comprising a central bore and one or more outlet bores in fluid communication with the central bore for communicating with a respective fuel injector. The outer circumference of the rail body is substantially oval in cross-section and is thicker in cross-section in a direction substantially perpendicular to the outlet bore axis as compared to the thickness in cross-section substantially parallel to the outlet bore axis. By increasing the thickness of the rail body in this way, stresses at the intersection of the intersection of the central bore with the outlet holes may be reduced by up to 10% or more, thereby increasing the acceptable cycled running pressure of the system.

Abstract: The present invention relates to a connector system comprising a plug connector and a retainer configured to be inserted into a corresponding holder. The plug connector comprises a connector housing and a latching arm assigned to the connectorhousing, whereby the plug connector is configured to be mountable with the retainer. The connector system comprises a deflection portion for causing the latching arm to deflect upon mounting of the plug connector with the retainer. The deflection portion is shaped such that the deflection provides increasing resistance against further movement of the plug connector. The connector system further comprises a release portion configured to enable a release deflection of the latching arm. The release portion is shaped so the release deflection does not provide resistance against further movement of the plug connector. Still further, the connector system comprises a latching portion configured to allow the latching arm to lock the plug connector.
