“…Figure 1b presents emission standard of European Union for heavy duty vehicles (Delphi, 2012), NO accounts for 90% of total NOx emissions, with the remainder being NO 2 (Hebbar, 2014). The diesel engine has an efficiency of about 35%, and about 25 and 40% energy is lost in cooling system and exhaust heat, respectively (Hossain and Bari, 2014).…”

In order to reduce the CO 2 emissions in the transportation sector, one can electrify the vehicle, switch to biofuel, or capture and store CO 2 on board. In this study, integration of an on board CO 2 capture and storage unit with an internal combustion engine has been proposed. The technology can be applied for various internal combustion or Stirling engines with targeted applications in the transportation sector. Truck transport for goods delivery is used as an example for on board CO 2 capture and storage system design. The investigated system integrates a temperature swing adsorption system for CO 2 capture with a turbo-compressor system to compress and liquefy the captured CO 2 using the waste heat of the exhaust gases of the engine. Energy and exergy analyses of the proposed CO 2 captured system are studied in details. The CO 2 capture system for engine exhaust stream (car, truck, bus, ship, or train) can capture 90% of the emitted CO 2 , without any energy penalty. This system can be integrated into overall mobility system (fuel-engine-CO 2-fuel), where captured CO 2 can be recycled as conventional liquid or gaseous fuels produced from renewable energy sources.

“…In a typical energy flow path of an internal combustion engine, only 25% of the fuel combustion is utilized for vehicle operation, whereas about 70% of the total fuel energy dissipates to the environment as heat loss primarily through the vehicle exhaust system and radiator [3]. Heat available in the exhaust gas of an engine can be an important heat source [4].…”

A conventional car engine uses at best about one-third of the fuel combustion energy, while the rest of the energy is lost in friction and most in heat. In the face of the new emission regulations proposed by the government due to the high levels of pollution, and with the aim of achieving cleaner and more efficient transportation, vehicle exhaust gas recovery is being researched in the last years. It is of interest for the automotive industry to recover this wasted energy, thus increasing engine efficiency, reducing fuel consumption and pollution. One way to achieve both objectives is the conversion of engine waste heat to a more useful form of energy, either mechanical or electrical. This paper study a system prototype based on Brayton´s thermodynamic cycle driving an Electrical Generator to recover energy from the exhaust gases from a commercial internal combustion engine.

Around a third of the energy input in an automotive engine is wasted through the exhaust system. Since numerous technologies to harvest energy from exhaust gases are accessible, it is of great interest to find time-and cost-efficient methods to evaluate available thermal energy under different engine conditions. Computational fluid dynamics (CFD) is becoming a very valuable tool for numerical predictions of exhaust flows. In this work, a methodology to build a simple three-dimensional (3D) model of the exhaust system of automotive internal combustion engines (ICE) was developed. Experimental data of exhaust gas in the most used part of the engine map in passenger diesel vehicles were employed as input for calculations. Sensitivity analyses of different numeric schemes have been conducted in order to attain accurate results. The model built allows for obtaining details on temperature and pressure fields along the exhaust system, and for complementing the experimental results for a better understanding of the flow phenomena and heat transfer through the system for further energy recovery devices.
