Abstract
A test stand for testing multiple engines which may be liquid cooled or air cooled including apparatus for preheating a liquid coolant to preheat the engine prior to testing, apparatus for heating lubricant for preheating the engine prior to testing, apparatus for conserving the heat through heat exchangers to heat the coolant and the lubricant for a supply of coolant and lubricant for testing a successive engine; a brake and drag for the engine arranged for generating electricity to obtain electrical energy from the testing forces. For an air cooled engine, a throttle arrangement is added to block the air for a fast heating of the engine prior to testing. In one form, lubricant is bypassed from the sump up to the head of the engine and heated in the bypass such as by a heat exchanger energized by heat from the coolant from testing a previous engine.
