Photo oxidation analysis method for automotive coating weathering performance evaluation

2019-11-21
2019-28-2555
RESEARCH OBJECTIVE Accelerated artificial weathering performance has been always observed as critical and most important factor for durability prediction of colour and resin for a coating system. Photo oxidation of resin is the phenomenon behind coating’s ageing. Though accelerated weathering tests protocols are widely used in industry, they are very costly and still very time consuming. One automotive grade accelerated testing can go as long as 8 months duration. METHODOLOGY (maximum 150 words) Photo oxidation value (POV) is proportionate to the degradation of the resin material used in coating. During the accelerated weathering POV is measured for the coating at stipulated interval during initial phase and trend is plotted for deterioration verses weathering test duration. POV can be analysed with the help of FTIR analysis to observe bond absorption energy and bond separation energy in the resin system. This trend can be extrapolated to predict the weathering performance of coating.

The need of Diesel as fuel has greatly pressurized the now scarcely available natural resources and is likely to become a luxury for the future generations. This paper aims at finding an alternate for diesel that can hopefully reduce the pressure on its existing demand. This paper presents a comparative study on use of different blends of Jatropha Oil (J) and Ethanol (E) as fuel in a diesel engine to observe its performance and emission characteristics. The findings are later compared with corresponding values of neat Diesel as fuel. Since Jatropha oil is more viscous and has polyunsaturated characteristics in its natural form, its ethyl ester was produced by transesterification process and later blended with Ethanol in different proportions like 90% J 10%E, 80J-20E, 70J-30E and 60J-40E.

The diesel engine is widely used for its high thermal efficiency and better fuel conversion efficiency. However, increasing usage of petroleum fuel and environmental degradation motivates to use renewable biofuels as a replacement to conventional diesel. Biofuels produced from non-edible sources can be used as a partial substitute of diesel for the significant growth of fuel economy and reduction of environmental pollution. Methanol can be implemented as a blended fuel in the diesel without affecting engine design. In this study, the effect of diesel methanol blends and injection parameters such as fuel injection pressure (FIP)and start of injection (SOI) on a common rail direct injection (CRDI) diesel engine performance and emission were investigated. Four blends were prepared by mixing diesel with methanol (5%, 10%, 15% and 20% by mass) and adding a certain amount of oleic acid and iso-butanol to get a stable blend.

The research work intends to assess the need and improvement of using a low viscous bio oil, RH (Rice Husk) Nano Particles and water injection method in enhancing the performance, emission and combustion characters of a diesel engine. One of the major setbacks for using biodiesel was its higher viscosity. Hence, a low viscous oil (Pine oil) which doesn’t need transesterification process was used as a biofuel in this study. To further improve its characteristics a non-metallic Nano additive produced from rice husk was added at 3 proportions (50, 100, 200 ppm) and the optimal quantity was found as 100ppm based on the BTE (brake thermal efficiency) value of 30.2% at peak load condition. This efficiency value was accompanied by a considerable decrease in pollutants like HC (Hydrocarbon), Smoke, CO (Carbon monoxide). On the contrary NOx (Oxides of Nitrogen) emission was found to be increased for all load values.
