Therefore, to reduce the jet noise generated by the exhaust of the PAM, a silencer that mimics the gill slit structure of a shark and applies the noise reduction principle was developed. The study aimed to experimentally analyze the developed silencer to reduce the exhaust noise caused by the operation of a pneumatic system, such as a PAM.

About Photovoltaic Energy StorageWhen the sheer noise level reduction and noise cleaning has taken place, one can start creating sound almost as a musician who starts composing on an empty sheet of music. It is worth noting, that in modern vehicles with powerful diesel engines this noise reduction and cleaning is achieved more easily than for gasoline engines due …
About Photovoltaic Energy StorageGray cast iron (GCI), because of its outstanding dampening properties and great thermophysical parameters (melting point, thermal conductivity, and heat storage capacity), is the most often utilised brake disc material, which helps decrease overheating, braking decibel sounds, and brake friction fade [49], [50], [51], [52].
About Photovoltaic Energy StorageBy increasing backpressure to the engine, the exhaust brake forces the pistons to push against additional force during the exhaust stroke, slowing the crankshaft''s rotation and helping to control the vehicle speed. Overall, this requires less use of the service brakes, giving them a longer life and reducing the overall cost of ownership.
