The project is jointly undertaken by three institutions including Tianjin University and Weichai. The project achievements creatively proposed a torsional vibration damper plus frequency damper composite damping; the use of exhaust gas recirculation to suppress diesel transient combustion noise; combined with the powertrain overall modal, mass, inertia distribution characteristics of the suspension system and structure Optimized design; methods for calculating the insertion loss of exhaust gas particulate filter for internal combustion engines, etc., effectively reducing engine transient combustion noise and structural vibration noise.

It is reported that in 2013, Weichai’s “Key Technology and Industrialization of Heavy-duty High-Speed ​​Diesel Engines ” won the second prize of the National Science and Technology Progress Award.
