Research on the design of a non-commercial impulse compressed air supply system for the turbocharger of a spark-ignition internal combustion engine

A compressed air pulse directed to the turbocharger of an internal combustion engine can significantly improve the power and torque buildup characteristics. This article presents the design and testing of a universal compressed air delivery system, demonstrated using a Volvo V70 2.0 Turbo vehicle. The proposed solution offers a retrofit approach for older engine designs, inspired by the PowerPulse system, which was first introduced commercially by Volvo in 2016 in the S90 model. The non-commercial prototype tested in this study increased engine torque by up to 13% within a selected rotational speed range (1700 to 2400 rpm). Simultaneous changes were also observed in the manifold absolute pressure (MAP), lambda sensor readings, injection timing, and air mass flow in the intake manifold..
