Abstract

In this study, an alternative stationary exhaust noise test of motor vehicles was investigated. Exhaust noise level measured by current ISO5130 does not correspond well with accelerating vehicle noise, because ISO5130 measures noise in engine coasting condition. To solve this problem, an alternative stationary exhaust noise test was proposed. This test measures when the throttle is opened quickly and fully from the idle position. The results were compared with those of the current ISO5130 procedure and with the exhaust noise in the proximity of the exit of mufflers under full load acceleration condition. The exhaust noise levels of the new alternative test were almost the same as those under full road acceleration conditions from 50km/h based on current ISO362 on the chassis dynamo meter.
