Abstract EN
A three-phase sequential turbocharging system with two unequal-size turbochargers is developed to improve the fuel economy performance and reduce the smoke emission of the automotive diesel engine, and it has wider range of application than the current two-phase sequential turbocharging system.
The steady matching method of the turbochargers and engine and the steady switching boundary are presented.
The experimental results show that this system is effective to improve the engine performance especially at the low speed and high load.
The maximum reductions of BSFC and smoke opacity are 7.1% and 70.9%.
The optimized switching strategies of the valves are investigated, and the surge of the compressor in the switching process is avoided.
The switching strategies in the accelerating process are optimized, and the acceleration time from 900 r/min and 2100 r/min at constant torque is reduced by approximately 20%.
