Hydrous Ethanol

Hydrous-ethanol is reformed to hydrogen-rich mixture gas which is an excellent fuel for engines. The advantages of this approach are that fossil fuel consumption and CO2 emissions are reduced, and the waste heat from engine exhaust can be used as energy source for hydrous-ethanol evaporating and reforming. The experiment is carried out on a gasoline engine as primary engine with only modest changes. The results indicate that the hydrogen-rich mixture gas allows operation at much higher compression ratio due to its intrinsic octane number which could contribute to the power performance, and the NOx, CO, THC emissions are reduced remarkably because of lean combustion realized in the cylinder.

The energy efficient technology in the automobile is the need of hour due to energy crisis as well as environmental problems. This paper deals and describes the feasibility of utilizing the dissipated waste heat energy from the exhaust manifold of an automobile engine .It involves the vibration of nano level thin carbon material. The waste heat energy is utilized to obtain thermo elastic vibration of required frequency. By using the piezoelectric principle, generated vibrations can be converted into Electromotive Force (EMF). This paper briefs about the various carbon based material for this application and performance comparison.

Recovery Techniques

For many decades all major conservation bodies have realized the need to conserve our valuable fuel and power sources. The increased level of consumption of fuel and power results in carbon-di-oxide emissions to environment which results in the depletion of ozone layer leading to global warming. As a result, many ways of utilizing renewable fuel and power sources are developing with solar energy and waste heat recovery applications. Most of the process and industries have large capacity Diesel Generating (DG) set. The exhaust gas of such a DG set carries a lot of heat and it goes waste if it is not utilized properly. Energy recovery from engine exhaust is one of the energy saving methods in engines. By using energy recovery techniques, waste heat energy can be saved, emissions can be reduced and thermal efficiency of the engine is increased. This paper discusses about the exhaust gas energy recovery from engine exhaust using Rankine cycle and thermodynamic properties of the working fluids. The heat energy recovered from the engine exhaust can be utilized for various sources.

Heat Energy Recovery

The prime objective of this paper is to present the details of a thermoelectric waste heat energy recovery system for automobiles, more specifically, the surface heat available in the silencer. The key is to directly convert the surface heat energy from automotive waste heat to electrical energy using a thermoelectric generator, which is then regulated by a DC–DC Cuk converter to charge a battery using maximum power point tracking. Hence, the electrical power stored in the battery can be maximized. Also the other face of the TEG will remain cold. Hence the skin burn out accidents can be avoided. The experimental results demonstrate that the proposed system can work well under different working conditions, and is promising for automotive industry.

Up to 65% of the energy produced in an internal combustion engine is dissipated to the engine cooling circuit and exhaust gases [1]. Therefore, recovering a portion of this heat energy is a highly effective solution to improve engine and drivetrain efficiency and to reduce CO2 emissions, with existing vehicle and powertrain technologies [2,3]. This paper details a practical approach to the utilization of powertrain waste heat for light vehicle engines to reduce fuel consumption. The “Systems Approach” as described in this paper recovers useful energy from what would otherwise be heat energy wasted into the environment, and effectively distributes this energy to the transmission and engine oils thus reducing the oil viscosities. The focus is on how to effectively distribute the available powertrain heat energy to optimize drivetrain efficiency for light duty vehicles, minimizing fuel consumption during various drive cycles. To accomplish this, it is necessary to identify the available powertrain heat energy during any drive cycle and cold start conditions, and to distribute this energy in such a way to maximize the overall efficiency of the drivetrain.
