Motorcycle Engine Development System by Using a Test Bed with Simulation Technology
With the hope of efficient and sophisticated motorcycle engine development, an engine test bed that can simulate vehicle running conditions using an ultra-low inertia motor and high response load control system was constructed, and was applied to the development of engines. By combining an exhaust gas analyzer, an exhaust gas constant volume sampler (CVS), and a data processing system, mass emissions could be measured in various test cycles. This system's advantages for data repeatability and test efficiency compared with a chassis test using a vehicle were confirmed. An acceleration test was conducted to assess running performance, and good agreement with actual driving values was confirmed. In addition, by measuring and evaluating engine response to throttle manipulation, it was possible to evaluate driveability on the test bed. These test findings indicate that this test bed can simulate vehicle driving tests with the engine only and will be a useful tool in engine development.
