We conduct tests in this study to evaluate the appropriateness of various Plastic Pyrolysis Oils (PPOs) made from Low Density Polyethylene (LDPE), High Density Polyethylene (HDPE), and Polypropylene (PP) for diesel engine fuel. Determine which type of plastic pyrolysis oil would function best as an alternative fuel in an experimental investigation. The elemental composition of pyrolysis oil generated from LDPE, HDPE, and PP to diesel was assessed, tabulated, and compared in this study. This study examines emission characteristics (Nitrogen Oxide (NO X), Hydro Carbon (HC), and Carbon Monoxide (CO)) for Diesel, LDPE, HDPE and PP in CI engines using different injection pressure, compression ratio, and load in a specific configuration. In the result of experimental work the CO emission range for diesel and LDPE is exceeded only during overload situations or when the engine load is 100%. The average NO X emission is lowest when PP is used in comparison to other fuels, and the highest NO X emission occurs when LDPE is utilised as a fuel. Increased fumigation rates may be to blame for the rising hydrocarbon content of plastic oil. Unburned hydrocarbon levels are lower at lighter loads due to increased oxygen availability. The use of this whole pyrolysis oil results in a significant decrease in Nitrogen Oxide (NO X), Hydro Carbon (HC), and Carbon Monoxide (CO) exhaust emissions. With the help of this current study. one can solve plastic waste disposal problem and also find any unknown fuel (PPOs) that can be used as an alternative fuel for CI engine or not.

It surveys most literature published in English language. The review aims to provide insight into the truck chassis design and act as a guide for researchers working on both FEA and DOE method for chassis design. The main objective of the design is to obtain the optimum weight of the chassis. This optimum design is being constrained by the maximum stress, stiffness and the natural frequency requirements. The number of cross members, their locations, cross-section and the sizes of the side and the cross members becomes the design variables. As the chassis frame is analyzed using the finite element techniques, appropriate model of the frame is to be developed. Then by comparing them we can get the best solution. Since the no. of parameters and levels of parameters are more, the probable models are too many. So, to select optimum parameters among th...

So to reduce NOx emission it is necessary to keep combustion temperature under control. Late injection of the fuel is one of the simplest way to keep NOx formation in control. Though this technique is very effective in NOx formation control, it is not fully acceptable due to increase in fuel consumption up to 10-15%. This leads the research to use more effective NOx reduction technique like Exhaust Gas Recirculation (EGR). Recirculating the Exhaust gas reduces the NOx emission but on the other hand there is increment in Particulate Matter. With increase in EGR rate there is decrement in NOx emission. But due to well-known tradeoff between NOx and PM it is necessary to use PM Trape like catalytic convertor. In present study, the effect of diesel engine parametric optimization, for NOx reduction, on engine performance has been investigated. A...

The use of vegetable oils as a fuel directly in diesel engines causes some problems due to their high viscosity compared with conventional diesel fuel. Various techniques and methods are used to solve the problems resulting from high viscosity like preheating, blending, Esterification etc. One of these techniques is fuel blending. Find the best blend and add the ethanol in that blend in the 5%, 10% and 15% find the engine performance and emission characteristics. Engine performance and emission were investigated and compared with the ordinary diesel fuel in a diesel engine. Experimental results show that the engine power and torque of the mixture of sesame oil–diesel fuel are close to the values obtained from diesel fuel and the amounts of exhaust emissions are lower than those of diesel fuel. It is concluded that it is possible to use Sesame oil in diesel engines as an alternate fuel in the future without modification in the engine.

Pyrolysis oil is obtained from tire waste by pyrolysis process. Pyrolysis process is a therm-o-chemical decomposition of organic matter in absence of oxygen. Blending of pyrolysis oil with diesel helps to reduce the consumption of diesel fuel. Diesel engine is already optimized for particular fuel i.e. diesel. So, it does not give optimum performance for pyrolysis and diesel blend. In this study, parameters i.e. load, blend proportion and injection pressure were taken as variable for optimization. Optimization of these three parameters is done by DOE (Taguchi Method), which gives optimum performance for given bland.

Equations for tangential and radial stresses were established from equilibrium, constitutive, compatibility relations and Fourier’s heat conduction equations for temperature specified boundary conditions of different thermal gradients. The analysis has been carried out by varying volume fraction of steel wire reinforcement with two independent Al & CI matrix materials. The values of tangential and radial stress com¬ponents that have occurred under the effect of the temperature gradient across the outer surface of the disc towards the inner surface have been obtained by both analytical and numerical method using FEA. The results of analytical analysis and numerical analysis are closely matches. The results shows the thermal stresses generated in cast iron-steel composites are higher than the aluminium-steel composites.

The chassis serves as a frame work for supporting the body and different parts of the automobile. Also, it should be rigid enough to withstand the shock, twist, vibration and other stresses. Along with strength, an important consideration in chassis design is to have adequate bending and torsional stiffness for better handling characteristics. So, strength and stiffness are two important criteria for the design of the chassis. This report is the work performed towards the optimization of the automotive chassis with constraints of stiffness and strength. Structural systems like the chassis can be easily analyzed using the finite element techniques. An optimization algorithm will then require several structural analysis to reach the optimum point. So a proper finite element model of the chassis is to be developed. The chassis is modeled in PRO-E. FEA is done on the modeled chassis using the PRO/MECHANICA. The results of the optimization are presented in this Book.

Web thickness, upper flange thickness and lower flange thickness of the sidebar are considered as input parameters. Sets of parameters for chassis frame variants are designed by employing Response Surface Methodology (RSM) in statistical software, " MINITAB 16 ". The regression equation for VMS is developed using the Finite Element Analysis (FEA) results of different variants of the chassis frame. The analysis of variance (ANOVA) is performed to statistically analyze the results. The individual effects of parameters and the combined effects of multiple parameters are examined. Among the variable web thickness and lower flange had the most significant effect on the stress generated.

The chassis frame is made of two sidebars connected with a series of crossbar. The web thickness, upper flange thickness and lower flange thickness of sidebar becomes the design variables for the optimization. Since the number of parameters and levels are more, so the probable models are too many. The variants of the frame are achieved by topology modification using the orthogonal array. Then Finite Element Analysis (FEA) is performed on those models. RSM model and MLR model are prepared using the results of FEA to predict equivalent stress on the chassis frame. The results indicate that predictions of RSM model are more accurate than predictions of MLR model.
