A versatile hydraulic engine test bed with comprehensive instrumentation. The equipment is fully compatible with Versatile Data Acquisition System. Using this enables accurate real-time data capture, monitoring and display, calculation and charting of all relevant parameters on a computer making tests quick and reliable. When used with one of optional single-cylinder engines, it safely and effectively enables study and demonstrations of the most important features of the engine. In addition, optional ancillaries are available to extend the range of study, demonstrations and investigations even further.
The main components of the test set are:
A bench-mounted instrumentation frame
A heavy fabricated portable bed
The bed sits on a trolley for portability. It includes a robust, precision-machined, trunnion - mounted hydraulic dynamo meter. A significant advantage of using a hydraulic dynamo meter is that no large electrical supplies are required as the engine power is dissipated into the water used to load the dynamo meter.
