| Abstract(E) | This paper investigates an "Exhilarating" engine sound quality for in-line four cylinder downsizing turbocharged engine. The downsizing turbo engine can realize quietness by lowering the rotational speed in combination with the Continuously Variable Transmission. On the other hand, noise and vibration caused by combustion tends to be a problem at low and middle rotational speed range due to high load operation. The relationship between the rumble sound generated at this engine operation condition and the target "Exhilarating" was clarified. And each part was promoted goal setting and countermeasures for achievement "Exhilarating" engine sound. Furthermore, we considered the difference between the sound quality "lightness" that was clarified in the previous research. |
