Variable frequency tuning part | ||
Sin.VTE variable frequency tuning part – which can be used for the complete vehicle tuning. ➢ With the help of Sin.BAM, you can find the influence of air intake noise to the vehicle interior at the frequency of the problem point; ➢ Combined with the vehicle front compartment package layout, design the available tuning volume and the length of connecting pipe; ➢ Sin.VTE software can be used to calculate the diameter of throat pipe. Sin.VTE can be applied to tune engine bench ➢ Provide air intake tuning facilities for the engine bench | ![]() | |
![]() | Tuning specifications ➢ Sin.VTE tuning part volume scale: 0.4 ~ 4.2L; ➢ Inner diameter of throat pipe: 15~50mm ➢ Equivalent length of throat pipe: 80~205mm ➢ Tuning frequency: 63Hz~400Hz |
Auxiliary Muffler | |
![]() ![]() | Sin.BAM auxiliary muffler is applied in the vehicle chassis dynamometer with anechoic chamber ➢ Shield the noise of the intake port and exhaust port, and identify the influence of the noise of the intake port and exhaust port on the roar of the car ➢ Objectively evaluate the sound transmission loss that the noise from the intake port and exhaust port is transmitted to the vehicle body; ➢ ectively evaluate the contribution rate of the noise order of the intake port and exhaust port to the noise inside the vehicle; ➢ Break down the overall noise goal of complete vehicle to the intake port and exhaust port; Sin.BAM is applied in the engine bench with anechoic chamber ➢ Evaluate the contribution of noise radiation from intake port and exhaust port to engine noise |
