Why is the vibration of Suzuki Feng Yu more obvious after upgrading the system?

The design of the front-end car considers fuel saving and weight reduction, and the engine keeps the economical speed of the vehicle at a low speed. At this time, after overcoming its own resistance, the low speed of the engine has only a small torque output, which also drives the gearbox. Because of the lack of power, the engine and gearbox shake and produce vibration. Coupled with the thinner body steel plate, resonance is formed and vibration is amplified. This is the * * * vibration that everyone feels when the engine is running at low speed.

There are only five forward gears in the manual gear. Old drivers know that vehicle jitter is a sign of insufficient engine power, so they will downshift, thus increasing the engine speed and transmitting more powerful power to drive the vehicle, which will eliminate the jitter phenomenon. However, the front car body is lighter. At this time, even if you don't downshift, the car won't die and you can still run. Some people do not downshift for the ultimate fuel-saving effect, but will increase the vibration of the vehicle.

This can explain why the vibration of manual transmission models is not obvious, because few people stay in this speed range with insufficient power for a long time. CVT models simulate 7 gears. Some people cruise at 900 rpm to save fuel, but the vibration is obvious.

Therefore, while pursuing the ultimate fuel economy, Feng Yu of Suzuki has long had the phenomenon of * * * vibration.
