The engine is run for a period of time until it has been brought to equilibrium. When thermal equilibrium has been established, the test is started. The procedure is to establish fuel consumption based on the mass of fuel consumed within a specified period of time. Furthermore, to minimize fuel consumption and exposure to the hot, noisy test environment, each lab group will make two test runs. Each group will get an additional set of data points for this engine.
Reports are to be based on the entire data set.
Test Equipment Engine See data on the Toyota 4A-F engine at end of the handout. Therefore, do not be surprised if your results for torque and horsepower are somewhat different. The device has a capacity of 1000 hp. The dynamometer contains one perforated disc, which rotates in a housing between a similar set of perforated stators. Cold water enters the rotor chamber at the center.
