A robust floor mounted engine test stand withmodular instrumentation and control system. A regenerative dynamometer includesboth torque and speed control together with direct reading dynamometer digitaldisplay. The dynamometer will accept engines up to 4kW shaft power output. Enginespeed and all relevant temperatures are also displayed on digital panelmeters on the remote instrumentation console. Air to the engine passes throughan intake orifice and pulsation damper. The flow measurement orifice isconnected to a panel mounted manometer to allow differential pressuremeasurement. Fuel flow is measured using a calibrated volumetric fuel gauge. Eachof the optional engines are pre-installed on a standard mounting plate that isdesigned to allow quick and easy installation on the test bed.
