Abstract: In this work, a novel air hybrid engine configuration is introduced in which cam-based valvetrain along with three-way and unidirectional valves make the implementation of different engine operational modes possible. In the proposed configuration, an electronic throttle system is used to manage the engine load in both conventional and braking modes. The necessity of engine torque control during regenerative braking is discussed and a lookup table/PI controller is applied to the engine model in GT-Power to control the engine torque at the regenerative mode. It is shown that utilising the proposed configuration, the regenerative braking mode can be simply implemented and the braking torque can be regulated by controlling the throttle angle.
