TEST STAND FOR DIESEL ENGINE FUEL DEVICES Russian patent published in 2002 - IPC

FIELD: mechanical engineering; testing facilities. SUBSTANCE: proposed diesel engine fuel equipment test stand has the following devices intercoupled and mounted on common base: mounting plate for device to be adjusted, output shaft with flywheel, tachocounter, control unit with drive with electric motor, stand control panel, fuel supply pressure control unit with service tank and metering unit with foam killing unit. Foam killing unit has special device to provide continuity of fuel flow installed in lower part of unit. Continuous fuel flow forming device is made in form of ring cylindrical enclosing chamber and detachable fuel divider in form screen and service volumetric groove with T-shaped cross-section and outlet chamber to adjust height of fuel flow. EFFECT: improved quality of operation of stand owing to increased stability of output shaft speed and improved accuracy of control of pressure of fuel fed to device under testing, prevention of instability of testing owing to provision of continuous fuel flow, simplified design of drive and reduced materials usage. 19 cl, 2 dwg
