Abstract

Conventional automobiles employ Internal Combustion engines (IC engines), which emit a large quantity of heat. Combustion heat radiates a significant amount of heat into the atmosphere; nevertheless, this wasted heat can be used in our heat recovery system, that transforms waste heat into useful energy. The utilization of thermal energy that would otherwise be lost to the environment to perform a useful activity is known as waste heat recovery. A hybrid vehicle has both an internal combustion engine and an electric powertrain either connected in series or parallel. This heat recovery system can be used in a hybrid vehicle to recover useable energy in the form of electrical energy for later use. The heat is dissipated by convection in the powertrain or engine, where it is transferred to the cooling circuit or lost out the exhaust pipe as exhaust gases. The heat recovery unit is a thermochemical recovery system that can be fitted in an engine's cooling system. The engine's coolant heat can be used to turn a working fluid into steam which in turn can be used to power a turbine to produce electricity. Also it can be stored in a battery pack and used for productive work in a hybrid vehicle. As a result of this design, we may obtain greater range and improve the hybrid system's overall effectiveness.
