Enhanceement of the Engine Acceleration by Using Compressd Air

Abstract

Experimental work has shown that injecting air into the manifold greatly improves the transient response of the turbocharger. This work has shown that air injection has a large upon improving the transient response when performing rapid load changes, which result in increases engine torque output while minimizing the potential for exceed various operating limits to the maximum practicable extent, moreover the transient performance has improved which lead to a significant reduction in the harmful emissions. The vehicles air injection system controller implements strategies for shaping the rate of the air injection during a boost event, by controlling the timing, duration, quantity and or injection pattern during a boost event to achieve a refined distribution of compressed air injection over the course of the boost event to provide desired engine torque output and fuel efficiency while minimizing the potential for exceeding a wide variety of operation limits, regulatory, engineering and passenger comfort limits.
