Experimental Investigations of a Novel Modular Pulse Converter Turbocharging System for Vehicle Engines 1999-01-1245

With the continuous progress of the engine technology, turbocharging technology is being developed and improved to meet more strict requirements of the fuel economy and exhaust emission of vehicle engines. At present, a very important part of the design and research of turbocharging system is to find a way to improve the transmitting efficiency of exhaust energy and turbine efficiency both in part-load and full-load power curves over the speed range. The pulsing turbocharging system widely used in the vehicle engine of low supercharging level and three-multiplied cylinders is not completely satisfactory since it is complicated in structure and difficult to keep high fuel economy in full range of running. This paper presents the scheme employing a Modular Pulse Converter (MPC) turbocharging system in the engine of low supercharging level and three-multiplied cylinders. With the consideration of the characteristics of structural arrangement of some vehicle engines, the mid-settled turbocharging system with a novel MPC structure is designed and a large amount of experimental investigations have been done. The results show that a fine-designed MPC turbocharging system is completely suitable for this type of engines. This paper provides some considerable insights to turbocharging system's designs and research for the future.
