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.

Published 2018-07-09 by SAE International in United States
In the present study, an aluminium based nanocomposite, reinforced with 2 wt. % aluminium oxide (Al2O3) is developed through stir casting method. These hard ceramic particles also influence the material removal rate (MRR), electrode wear rate (EWR) and surface finish (Ra) in an electro-discharge machining (EDM) process. In this work, EDM of Al 7075/2 wt. % Al2O3 nanocomposite is carried out using copper and brass electrodes using Taguchi L18 array. The percentage contribution of each process parameter on the response variables was determined using analysis of variance (ANOVA). Multi-response signal to noise ratio (MRSN) and the optimum combination levels for the input parameters was obtained using Taguchi’s parametric design. MRR and surface roughness are substantially improved when machining is performed at optimized conditions.

The depletion of fossil fuels and environmental degradation with its emissions motivated the researchers to search for alternatives. Vegetable oils are considered as one of the productive alternative for internal combustion engines because of good combustion properties. Currently, very few commercial devices that utilize bio-diesel combustion for the production of heat, due to the economic viability and limited availability. To attain effective combustion, an effort is made in investigating the effect of change of piston geometry on the Performance & Emission characteristics of bio-diesel of mahua oil. Experiments are conducted to study the effect of varied piston bowl geometry on the performance and emission characteristics of mahua oil biodiesel on four stroke single cylinder diesel engine at constant speed of 1500 rpm for different loads. It is noticed that, at 20% blend of biodiesel of Mahua oil, the performance and emission parameters were improved compared to alone diesel operation. Hence the same optimal blend is adapted for conducting experiments by changing piston bowl geometry of toroidal shape. The experiments are conducted duly ensuring the same…

Published 2018-07-09 by SAE International in United States
This paper describes the development of a varying stiffness suspension system to have better control over handling, comfort and structural fatigue of automobiles. Earlier approaches resulted in cumbersome designs and resulted in higher lateral forces on coil springs and structural fatigue. In this work, an initiative has been taken considering all these factors and optimizing the design at every stage of development to achieve lightweight and economical suspension system to meet the objectives. The variable stiffness is achieved through the relative travel of spring with respect to the wheel travel for different configurations. For this purpose, a stepper motor drive is employed to move the hinge point in the angular arch. The developed design is also examined through mathematical modeling and the MBD simulations. It is found that that the proposed design has the capability of facilitating better handling and comfort characteristics without much compromise on the overall cost of the suspension system.

Published 2018-07-09 by SAE International in United States
The objective of this work is to examine the suitability of cooling airflow non-uniformity on radiator frontal surface as a factor to evaluate three attributes: airflow distribution, front fascia geometry and deterioration in heat rejection. In literature, the effect of front end design is investigated by evaluating the volume of cooling airflow passing through the radiator and cooling drag of a vehicle. In this study, it was demonstrated that airflow distribution on radiator frontal surface can also be considered as one of the parameters while choosing the front-end design. Using the basic equations for modeling the cooling airflow through a front-end opening, CFD approach is developed to quantify the airflow distribution over the heat exchanger(radiator) as a function of flow statistics of the upstream cooling air. Further, this work is extended to study the impact of airflow non-uniformity on the thermal performance of radiator using the empirical equation available in literature. The airflow non-uniformity was found to be sensitive to changes in the geometry of fascia particularly around the upper cooling inlet. This study reveals…

Published 2018-07-09 by SAE International in United States
Though high thermal conductivity polymer composites are prepared based on the thermal requirements, the effectiveness and overall heat transfer performance of the radiators have to be addressed comprehensively to validate the concerned efforts taken to prepare the high thermal conductivity polymer composites. In this article, theoretical analysis on the thermal performance of the cross flow type heat exchanger under convection is performed only by concentrating on the term thermal conductivity of the material. Micro channel based geometry is extracted from the given heat exchanger problem to reduce the complexities of simulation. The term cooling system performance index (CSPI) is used to achieve the expected targets in the present investigation. For shorter fins, the effect of thermal conductivity on the cooling system performance index under lower Reynolds number is insignificant. Further discussions on effect of thermal conductivity on various cases are presented with brief explanations.

Agriculture is a backbone of country’s economy. To increase the crop production efficiency weeds are to be removed. The present weeding machines are different in dimension which may not be suited to small and medium field farmers, due cost effectiveness and dimensions. This work presents the development of sugarcane weed remover (SWR) and its performance investigation to improve the weed removal rate. The SWR is an application specific machine, it consists of single cylinder air cooled gasoline engine, blade assembly and transmission system. In order to improve SWR efficiency different blade profiles are theoretically analysed. The optimised blade profile is employed in the weed remover which offers fuel consumption of 0.11 g/(KW.h). The SWR on-field experience confirmed that the field capacity and efficiency in weeding is 0.0025 ha/hr and 60% respectively.

A model for Hybrid electric vehicle power train with parallel hybrid braking system has been constructed. The hybrid vehicle utilized is based on integrated motor assist power train developed by Honda co utilized in Honda Insight car. The model is implemented using empirical formulation and power control schemes. A power control strategy based on throttle position (% throttle) and brake pedal position (% braking) is used. It incorporates the parallel hybrid braking system for the hybrid electric vehicle. The model allows for real time evaluation of wide range of parameters in vehicle operation as HEV without parallel hybrid braking system (PHBS) and with PHBS. Due to regenerative braking the structure design and control of braking system for HEV is different from conventional vehicle. The PHBS is the good option to provide safety of the vehicle and simultaneously recover reasonable amount of braking energy. In this paper a model for HEV is developed and simulated to evaluate major performance parameters on three different approximate drive cycles (NYCC, HWFET and WVU5).
