Title: EXPERIMENTAL STUDIES ON THE EFFECT OF DIFFERENT OXYGENATED ADDITIVES ON THE PERFORMANCE OF SPARK IGNITION ENGINE
Biography:
Dr.Danaiah Puli working as a Professor in the Mechanical Engineering Department, Ramachandra College of Engineering Eluru, Andhra Pradesh. He awarded Doctorate from National Institute of Technology Warangal in the area of IC Engines. He had completed M.Tech from JNT University Anantapur in Refrigeration and Air Conditioning. He published 15 papers in different SCI International journals and attended National and International Conferences. He visited Germany for one week Program on “Advanced fuels for sustainable Mobility” as a keynote speaker in FEV-2016 through MHRD travel grant
Abstract:
This paper examines the sensitivity of oxygenated additives (Methanol and TBA) blends to various engine parameters like performance and emission characteristics of the test engine under various operating conditions using single tip and multi tip spark plugs at differ-ent ignition timings ranging from 7° before top dead center (bTDC) as a manufacture speci-fied timing and by advancing the timing to 8, 9, 10 degree bTDC. The experiments are conducted in two different phases, in the first phase the experiments are conducted at constant speed variable load condition and second phase at constant load variable speed condition by changing the blend percentages from 0%, 3%, 5%, 7% and 10%. Among these blends 7% blends are predicated with the help of ANN tool environment in MATLAB by using the ex-perimental results. The ANN model accurately anticipates the performance and emissions of the engine.

Title: Safety Measures during product development & testing in an Engine Test Bed
Biography:
Gaurav Yadav is from Vel-Tech Rangarajan Dr. Sagunthala R&D Institute of Science and Technology, Chennai, India
Abstract:
Safety, both for machines and operators, should always be the first thing one must consider while the engine testing is carried on. The operators and the machines are one’s biggest assets and their safety directly impacts your productivity. Neglecting safety may prove fatal for both technicians and machines. Ensuring safety maximizes productivity by reducing operator fatigue and discomfort. Introducing smart features enabling new data acquisition techniques and monitoring features may help mitigating potential harm to dynamometers and the testbed. This will help in reducing the downtime and increase customer services. In this paper we have discussed few methodologies that will help companies in reducing incidents which hamper the testing, produce and capital

Title: Carbon Fiber Body Design with Surface Contrivance to Improve Aerodynamic Laws on Tractor-Trailer
Biography:
Prakash Shakti has completed B.Tech in Automobile Engineering from Doon College of Engineering and Technology in 2014, Dehradun (Uttrakhand), India and M.Tech in Automobile Engineering from Himalayan University in 2016, Itanagar (Arunanchal Pradesh), India and published 19 research paper in international journal related to Automobile Engineering and attended 1 Online international conference & 1 National Conference. Area of interest includes IC Engines, Advance Engine combustion technology, Vehicle Dynamic, Vehicle Aerodynamic, Vehicle Testing and homologatiom, Vehicle Designing and Analysis, Advance Vehicle Technology.
Abstract:
The main importance of this research is to improve tractor trailer aerodynamic by using a carbon fiber material on a trailer body and surface contrivance that means changing the shape of body design of trailer as well as tractor. By using Carbon fiber as a body material it provide proper aerodynamic stability and also reduction on wind noise because of light weight.
The research main focoused on changes of tractor trailer body design, the following changes has been done:-
- Cab deflector
- Trailer side skirt
- Wheel cowling (Trailer)
- Cab underbody air dam (Center Fitted)
- Air shield gap air passage
- Wider tire
- Trailer underbody triangular fairing
- Curve trailer body
- Trailer tail with air vanes
- Tractor corner vanes
- Extended cab panel with air vane (Tractor & Trailer Gap Filling)
- Internal air passage (rottating wheel air)
- Arc shape trailer frontal
- Tractor rear Spike (Pressure & Noise Decreaser)
The design has been done by using a 3D modelling software after that computation fluid dynamic simulation carried out. For air flow simulation the velocity of air was 80 kmph on actual dimensioned tractor trailer and by doing CFD there was many changes on trailer body like proper air flow, decrease in lift and drag forces also decrease in wind noise near to wheel and body. Changing the overall design lead to decreases aerodynamic forces by 33 % which thusly lead deprecation in fuel consumption by 2.7 %. It also provide better trailer stability in windy weather and cross wind condition dependes upon different driving condition.
Biography:
I’m Ganesh graduate of Mechanical Engineering in VFSTR University. We had done many projects during graduation and 4 Wheel Steering mechanism is prominent one. I had participated in ISEIC Go kart Competition in which we need to build our own Kart.We almost spent 6 months of time to do that project.
Abstract:
To understand the advantages of four-wheel steering, it is wise to review thedynamics of typical steering maneuvers with a conventional front -steered vehicle. The tires are subject to the forces of grip, momentum, and steering input when making a movementother than straight-ahead driving. These forces compete with each other during steeringmaneuvers. With a front-steered vehicle, the rear end is always trying to catch up to the di-rectional changes of the front wheels. This causes the vehicle to sway. As a normal part of operating a vehicle, the driver learns to adjust to these forces without thinking about them.When turning, the driver is putting into motion a complex series of forces. Each of these must be balanced against the others. The tires are subjected to road grip and slip angle.Grip holds the car's wheels to the road, and momentum moves the car straight ahead.Steering input causes the front wheels to turn. The car momentarily resists the turningmotion, causing a tire slip angle to form. Once the vehicle begins to respond to the steeringinput, cornering forces are generated. The vehicle sways as the rear wheels attempt to keepup with the cornering forces already generated by the front tires. This is referred to as rear-end lag, because there is a time delay between steering input and vehicle reaction. When thefront wheels are turned back to a straight -ahead position, the vehicle must again try toadjust by reversing the same forces developed by the turn. As the steering is turned, thevehicle body sways as the rear wheels again try to keep up with the cornering forcesgenerated by the front wheels.The idea behind four-wheel steering is that a vehicle requires less driver inputfor any steering maneuver if all four wheels are steering the vehicle. As with two-wheelsteer vehicles, tire grip holds the four wheels on the road. However, when the driver turnsthe wheel slightly, all four wheels react to the steering input, causing slip angles to form atall four wheels. The entire vehicle moves in one direction rather than the rear half attempting to catch up to the front. There is also less sway when the wheels are turned back to a straightahead position. The vehicle responds more quickly to steering input because rear wheel lag is eliminated.
