Experimental investigation of bleed flow turbocharger

The concept and basic principle of the bleed flow turbocharger are proposed. Design aspects and bench test experiments are discussed. By comparison with the characteristic of baseline turbochargers and predicting the performance of the engine with the bleed flow turbocharger, the authors conclude that the bleed flow of turbochargers is an effective measure to improve engine torque at low engine speed and to reduce the black-smoke and the brake specific fuel consumption (BSFC) for the engine.
