The Mechanical Seminar on SIX STROKE ENGINE designs a Beare Head,a new type of Six-Stroke Engine head design  which has an improved method for combustion process  to meet the  demads for low emissions and low fuel consumption in modern combustion engines.

There is just one common feature in majority of the actual internal combustion engines, operating on different cycles which is combustion occurring in the cylinder after each compression, resulting in gas expansion that acts directly on the piston (work) and limited to 180 degrees of crankshaft angle. According to its mechanical design, the six-stroke engine with external and internal combustion and double flow is similar to the actual internal reciprocating combustion engine. However, The four-stroke block, piston and crankshaft remain unaltered. This combination of two stroke and four-stroke technology has given the technology its name the “six stroke engine”.

The Six Stroke designed in this project is thermodynamically more efficient because the change in volume of the power stroke is greater than the intake stroke and the compression stroke. The main advantages of six stroke engine includes reduction in fuel consumption by 40% and its adoption by the automobile industry which would likely have a tremendous impact on the environment and world economy.

ADVANTAGES:

• Thermodynamically more efficient.
• Reduction in fuel consumption by at least 40%.
• Two expansions (work) in six strokes.
• Dramatic reduction in pollution.
• Multifuel

Mechanical Seminar on SIX STROKE ENGINE CONCLUSION:

The 6 Stroke Engine designed in this project is a solution for the replacement of the internal combustion engine which not only is an improvement of  the current technology,but  is within reasonable time and financial limits. And when allied with the so-responsive pickup and a wide spread of usable power with a bike, it makes the bike ridiculously easy to ride, hardly using the gearbox.

This Performance Improvement of a Di Diesel Engine Mechanical Seminar involves an Intensive search in developing diesel engine fuels and lubricants based on vegetable oils. Due to high viscosity of vegetable oils, they interfere with fuel jet penetration, atomization and results in higher fuel consumption and leaves gummy deposits on the engine components upon combustion. Investigations revealed that cotton seed oil, in general vegetable oils, can best be utilized if supercharging is employed at the recommended injection pressure of the engine.

In the present project the effect of supercharging is studied on the performance of a direct injection diesel engine with the use of untreated cottonseed oil. This project deals with the effect of supercharging on the performance of a DI diesel engine with the use of untreated cottonseed oil.

It is well known that supercharging improves combustion process of diesel engines Increase in pressure and temperature of the engine intake reduces ignition delay resulting in a quiet and smooth operation with a lower rate of pressure rise. Thus supercharging encourages the use of low grade4 fuels in diesel engines. The increase in intake air temperatures reduces the unit air charge and also reduces thermal efficiency moderately for the loss and inter-cooling is not necessary except for highly supercharged engines.

CONCLUSION:

This Seminar predict that Oil technologists over the next several decades will become just as essential for the transportation industry as fossil fuels like gasoline and diesel oil are today. Supercharging is also found to be essential when untreated vegetable oils are used for developing the power with a low specific fuel consumption compared to diesel operation and as the supercharging pressure is increased, the engine performance with untreated vegetable oils will be regarded as eco-friendly operation.

This Mechanical Properties of Foods Btech Seminar deals with the concept ofdeformation of food and explains how force causes these deformations on food items and commodities, with several examples and calculations.

The Seminar first explains that force causes acceleration to a commodity and occurs due to  phenomena such as gravity, magnetism, or anything else that causes a mass to accelerate. It describes Deformation as a change in shape due to an applied forcewhich when  considered can measure the “firmness” of a commodity.  The stress and strain experienced by a body is represented in the form of graphs such as Bioyield point (BYP)  Microstructure vs. Macrostructure and it also calculates the linearity in steel,rubber and corn.The different forms of deformations are also discussed such as Length deformation, Compression, Tensile / stretch, Shear and Bulk compression.

The shear forces acting on bodies are determined using modulus of elasticity, elastic ity elements,shear modulus, buls modulus,poisson’s ratio and viscosity etc.The shear forces deforming different bodies are also explained.And these calculations and study help in determining how force causes deformations in food items.

CONCLUSION:

Thus the project on mechanical properties in food explains the causes and methods of deformation of food items under force and the experiments conducted in this project helps the food corporation in studying the logitivity of food items based on such criterias.

The Bending Load Capacity Enhancement Using Asymmetric Tooth Profile aims at developing a new method to enhance the bending load capacity of gear tooth using Asymmetric Toothprofiles and thus improving the fatigue strength of the tooth by heat treatment or surface quality improvement.

Any power transmission devices operate in one direction, only one side of the tooth surfaces (the front oftooth) is in mesh. So the tooth is not necessary to be a symmetric form. Different standard pressure angles are used in the front and back profiles of an asymmetric tooth.

In this project, tooth root stress and bending stiffness of the asymmetrical tooth for several combinations of standard pressure angles were calculated by the use of finite element method. As gears are functional units used for transmission of power in transmission systems,fine module gears are used for low noise, vibration and for compact size of transmission system as the smaller gears will lead to insufficiency in bending load carrying capacity which is a serious problem in plastic and sintered gears.

CONCLUSION:

This project analyses  bending stress with the aid of FEM for asymmetric and symmetric tooth and has concluded that Asymmetric teeth have better performance than symmetric teeth for bending stress minimization.It has also found that as pressure angle on drive side increases, the bending stress decreases and bending load carrying capacity increases.The calculations were performed for not only the maximum stress but also the stress amplitude from fillet to tooth root considering the gearing procedure
