Description

Multi-nozzle type variable flow booster technical field The invention relates to a variable cross-section supercharger, in particular to a multi-nozzle type variable flow supercharging device that satisfies the requirements of high and low speed working conditions of the engine through the joint work of flow channels with different cross-sections. The field of internal combustion engines. technical background At present, superchargers are widely used in modern engines. In order to meet the performance and emission requirements of the engine under various operating conditions, the supercharger must have the adjustable function of boost pressure and exhaust pressure. Therefore, the variable cross-section supercharger Become the focus of research and development at home and abroad. Rotary vane variable-section turbocharger (VNT) and tongue-shaped baffle variable-section turbocharger are simple in structure and can effectively widen the matching range of turbocharger and engi...
