4 2017 Highlights Support BFCEC and EARD improve test quality of ISF2.8, obtain correct noise level at idle, by 2dBA lower than before (meet FOTON target). Complete driveshaft torsional vibration test with EARD equipment, add a new ability. Support Hyundai truck handle acceleration noise, engine abnormal noise, etc. Support CNHTC handle vibration issue, intake noise. Support JAC truck handle new pass-by standard test, vibration for a few vehicle models.

5 2017 Plan and Emphasis Pass-by noise simulation based on VMS.
Create a new CEB for 4-cylinder engine mount system design. Study a method for road load identification. Improve driveshaft torsional measurement for regular use. Optimize to support customers with best effectiveness.
