As much of any engine as is required to support and drive the component to be tested would be set up on the rig. For tests on valves and springs (see 12 above) an electric or steam heated oil tank would be connected with the standard oil pump for supplying oil to the crank and camshaft bearings. For tests on water pumps and additional electric or steam heated tank would be required for heating the water. Other requirements would be a venturi and U tube to measure flow, cocks on inlet and exhaust to regulate pressures and an indicator for pump r.p.m. It would be a simple matter to arrange fan fatigue tests on this rig. For tests on oil pumps, the oil inlet and exhaust pipes would be brought outside the sump so that pressure and flow could be observed. A second pump would be required to supply oil to the crank and camshaft bearings. Fuel pump endurance and efficiency tests should be easy to carry out on this rig and tests on complete chassis fuel installations could be made.
