This paper reviews all the key elements involved in setting up a engine test laboratory from the base building and services through to undertaking develomment and durability test prpogramms. Key elements of the paper will include the following interrelated topics: - The test cell as a system, inflows and outflows, energy balance within the cell. - The test cell design, how to avoid over or under provision of facilities, the place of the independent consultant in the equation. - The control room, general principles, minimum requirements, safety and security. - Ventilation, heat transfer from the cell, ducting considerations. - Vibration and noise, engine mounting, silencing, noise absorption characteristics of materials. - The design of systems for the passage of air, exhaust, coolant, fuel and oil to and from the engine. - Dynamometer selection. Differing research disciplines require differing dynamometer types. - Coupling the engine to the dynamometer, selection of prop shafts, dangers to be avoided. - Design of tests for Development and validation testing
