ABSTRACT Nowadays, the development of ICE is facing major challenges such as the exhaustion of traditional fuel sources, low thermal efficiency and environmental pollution emissions. Specifically, in the total amount of energy supplied to the engine through the transformation from chemical energy to the latent thermal energy in the fuel, only about 20 to 40% is successfully converted to useful work, the remaining thermal energy were being discharged into the environment through exhaust gas and engine cooling system. Therefore, taking advantage of this energy source is considered a challenging and promising research direction. Compared to utilizing heat of cooling water, the recovery and use of exhausted heat is much more efficient and easier because it has less impact on the structure and working process of the engine. This paper will summarize the prospects and challenges of the methods of utilizing exhausted heat currently being studied and used today. The content of the article can be used as a basis for research to improve the economics and techniques through optimizing the working conditions of the engine and for calculating the design of systems that utilize exhaust energy -engine cooling water. Keywords: Internal combustion engine, exhaust heat, heat utilizing. |
