Internal Combustion Engines Test Bed
The Internal Combustion Engines Test Bed is fully self-sufficient and designed so as to allow an easy interchange of the engine on the frame where braking dc generator and internal combustion engines up to 8 kW are coupled together. The braking dc generator can operate both as a motor in order to start the internal combustion engine under test and as a brake in order to measure its power output. A set of electrical resistances will dissipate as heat the output power which can be measured by means of a voltmeter and an ammeter. Then, the torque at the engine shaft will be calculated by measuring the revolving speed. The coupling of the braking dc generator to the internal combustion engine is obtained through a driving belt. The electric control panel and the instrument panel are housed on wheeled frames separated from the test frame so as to avoid the vibrations transmitted by the internal combustion engine. The fuel tanks are located on the instrument panel and feed the engines by gravity; the same panel holds the damper fitted with the calibrated orifice for the feeding and measurement of the intake air.
