Selection of Optimum Blend of Waste Plastic Oil-Diesel Blends Adapting Combinatorial Mathematics Based Approach

Published 2018-07-09 by SAE International in United States
In order to compensate energy demand while with replacement of fossil fuels at least to some extent, the development of alternative energy sources is evitable. Global warming and waste management policies have forced for the use of alternative fuels on engines. The production of fuel from plastic wastes will indeed tackle the environmental pollution problem of waste plastic management in the landfills. Plastics being derived from petrochemical source has higher amount of hydrocarbon which yield oil with high calorific value. Engine tests have been carried out using neat waste plastic oil and blends of waste plastic oil in proportions of 25%, 50%, and 75% with diesel as fuel. Combinatorial mathematics based approach has been adapted to choose the optimum blend for superior performance of the engine. Carbon hydrogen nitrogen sulphur analysis of waste plastic oil blends reveals that the amount of oxygen increases with increase in waste plastic oil percentage in blends. Results of combinatorial mathematics based approach and experimental tests showed that 25% of waste plastic oil with diesel is optimum blend.

Thermal Analysis and Experimental Investigations on the Effect of Thermal Barrier Coating on the Behavior of a Compression Ignition Engine Operated with Methyl Esters of Waste Cooking Oil

Hindustan Institute of Technology & Science-Sangeethkumar Elumalai, Jaikumar Mayakrishnan, Sasikumar Nandagopal, Selvakumar Raja, Sudip Mukherjee
Published 2018-04-03 by SAE International in United States
One of the globally challenging issues today is Waste Utilization. The excessive accumulation of waste has created an uncomfortable pressure on not, just the habitant but on the environment as well. As a small step forward in contributing towards minimizing waste disposal, this study attempts to address the problem raised due to the disposal of waste cooking oil. Researchers found that Waste Cooking Oil (WCO) has a very good potential as a fuel for compression ignition engine and was therefore selected for this study. In the first phase of the work, behaviour of the test engine was studied with neat WCO at different power outputs. As the first modification, neat WCO was converted in to its methyl ester and tested in the same engine. Next, combustion chamber parts like piston and cylinder head, inlet and exhaust valves were coated with Thermal Barrier Coating (TBC) and engine behaviour was studied. To make the study more interesting a thermal- stress analysis was done on the engine piston to examine the impact of coating on engine performance. Results…

Technological Proposal for Reduction of Residual Lubricating Oil In Oil Filters Removed from Automotive Engines

Institutos LACTEC-Alessandro Kulitch, Renato de Arruda Penteado Neto
Universidade Positivo-Bruna de Monaco Lopes
Published 2017-11-07 by SAE International in United States
In this study, a prototype oil filter was developed as a replacement for the shielded filters currently used in automotive applications. The goal was to reduce the residual lubricating oil disposed with a used filter. This is considered a Class I, waste (dangerous), under NBR 10004. Current Brazilian legislation, including CONAMA Resolution No. 362 of 2005, prioritizes the collection and disposal of used lubricating oil, and requires all contaminated material to be recycled or, where current technology does not permit this, to be sent to industrial landfills certified to handle toxic waste. To quantify the volume of residual oil in a commercial shielded oil filter, an experiment was conducted using 120 samples of a standard model. These samples were weighed before and after use. Before developing our novel design, a survey was conducted of professionals from the automotive field, to identify the main opportunities for progress. On the basis of the useful suggestions provided, a digital model and later a prototype were developed. The prototype was tested in an Otto cycle engine for 20,000 km.…

Published 2017-09-23 by SAE International in United States
In the Smart Cities, main objective is to promote cities that provide core infrastructure and give a decent quality of life to its citizens, a clean and sustainable environment and application of ‘Smart’ Solutions. The process said for utilization of available resources is the best fit for our concept. Our concept is to convert and refurbish the old and scrap vehicles which will increase their longevity and can be used in any smart city in India or abroad. The ultimate aim to provide this technology for the development of any new smart city in India is the utilization of available resources and reduction in the junk materials and environmental pollution. Refurbishing the old and scrap vehicles with replacement of IC engines doesn’t mean that they will be kept as a scrap and be thrown away, our idea is to utilize maximum of all the available resources. The IC engines taken out of these vehicles will be re-used appropriately. These IC engines in the vehicles will be replaced by an electric retro fitment kit which will…
