Abstract: This work analyses the existing Start-Stop systems. The proposed improvements to the Start-Stop system allow increasing its efficiency. Its feature is a second generator, and, thanks to it, the increased time and power of recuperative braking; besides, the engine can be stopped in a vehicle that is running by inertia or downward; at a certain speed of the car the engine is started without a starter; the energy of recuperative braking is used for electrical heating of the coolant. The paper presents a kinematic diagram of the transmission of a car with an improved Start-Stop system. A poly-V-belt drive has been chosen as a drive of the second generator. Experimental studies of the engine start in various modes have been carried out, the graphs of the dependence of the vehicle speed on the time are presented.

Keywords: energy recuperation; environmental safety; hybrid car; Start-Stop system; efficiency; generator; engine; plug-in hybrid vehicle.
