International Automobile Engine Mechanics Workshop (ROBOTRYST: 2014 -2015) organized at SGI

An International Automobile Engine Mechanics Workshop (ROBOTRYST: 2014-2015) was organized by Mechanical Engineering Department at Samalkha Group of Institutions on 17th and 18h October 2014.This workshop was organized by Er. Sunil Kumar (HOD, ME), Er. Rohit Rawat (Astt Proff. ME) and Er. Mohit Kumar (AP, ME). Rahul Kumar, Deepak Bhardwaj and Pushpinder Saini were the student coordinators in the workshop.
It was the two days International level Automobile Engine Mechanics Workshop (ROBOTRYST: 2014 -2015) in which maximum students of different years participated. This workshop centered towards the practical aspects of combustion engineering. The key Speakers were Er. Ankush Gupta (Robosapiens), Er. Ashish Kumar(Robosapiens) and Mr. Noor Khan (Robosapiens) Noida.
The highlights of the workshop were Practical Explanation, History of Engines, Recent Developments, Inside Theory of IC Engines, Catia Software, Robotryst Quiz and Live visualization & demonstration of the components & assembly of the entire engine.
The contents of the workshop were the basic principles of Internal combustion engine, Chassis design and its types with advantages and disadvantages, Suspension system its properties with types, Steering system, transmission system with its types, Fuel supply system, Gear box, Clutches, Differential, braking system, Anti lock Braking Systems (abs), balancing of engine, necessity of engine Cooling, Components of IC engine, Four wheel drive, Two wheel drive, SI engine and CI engine, Transfer box  Alternative fuels used in IC Engines, various design aspects of IC engines using Catia.
The internal combustion engine is an engine in which the combustion of a fuel (normally a fossil fuel) occurs with an oxidizer (usually air) in combustion chamber that is an integral part of the working fluid flow circuit. In an internal combustion engine, or ICE, the expansions of the high-temperature and high-pressure gases produced by combustion apply direct force to some component of the engine. This force is applied typically to pistons, turbine blades, or a nozzle. This force moves the component over a distance, transforming chemical energy into useful mechanical energy. The term internal combustion engine usually refers to an engine in which combustion is intermittent, such as the more familiar four-stroke and two-stroke piston engines, along with variants, such as the six-stroke piston engine and the Wankel Rotary engine. A second class of internal combustion engines use continuous combustion: gas turbines, jet engines and most rocket engines, each of which are internal combustion engines on the same principle as previously described.
A large number of different designs for ICEs have been developed and built, with a variety of different strengths and weaknesses. While there have been and still are many stationary applications, the real strength of internal combustion engines is in mobile applications . They dominate as a power supply for cars, aircraft, and boats.
The purpose of the Suspension System is to isolate the vehicle body from road bumps and vibrations, while keeping the wheels in contact with the road. A basic suspension system consists of springs, axles, shock absorbers, arms, rods, and ball joints.
Steering System is a system that allows a vehicle to follow the desired path. It converts the rotation of the steering wheel into a swiveling movement of the road wheels in such a way that the steering-wheel rim turns a long way to move the road wheels a short way.
Transmission system is the mechanism that transmits the power from the engine crankshaft to the wheels, providing the variable speed and torque at the road wheels as per the requirement.
Anti lock Braking Systems – (ABS) is an automobile safety system that allows the wheels on a motor vehicle to maintain contact with the road surface according to driver inputs while braking, preventing the wheels from locking up (ceasing rotation) and avoiding uncontrolled skidding.
Automatic transmission consists of several parts
Torque converter, input shaft, transmission pump, valve body, planetary holding members, etc.
Methods of transmitting power
Fluid, friction, and gears
Torque converter transmits power using fluid
Planetary holding members use fluid and friction
Gears transmit power and change speed and torque
Purpose of the Cooling system
Control temperature of hot combustion.
4000 degree temps. could seriously damage engine parts.
Provide Heat for passenger Compartment
Cool Trans fluid & Oil
Heat moves from warm to cold
Gear Design
Gears must have same pitch to operate together
Gear Pitch
o The number of teeth per given unit of pitch diameter
o To determine pitch: divide number of teeth by the pitch diameter of the gear
The Alternative fuels, known as non-conventional or advanced fuels, are any material or substance that can be used as fuel, other than conventional fuel. Conventional fuels include: fossil fuels (petroleum (oil), coal, propane, and natural gas), as well as nuclear materials such as uranium and thorium, as well as artificial radioisotope fuels that are made in nuclear reactors, and store their energy.
Some well known alternative fuels include biodiesel, bioalcohol (methanol, ethanol, butanol) chemically stored electricity (battery and fuel cells), hydrogen, non-fossil methane  non-fossil natural gas, vegetable oil and other biomass sources.
In Robotryst Quiz, many students participated in groups. Out of these, three groups were selected: first, second and third.
The first group was G1; Jatin, Salman Khan, Himanshu Chopra, Krishna Adhikari and Abhishek.
The second group was G12; Rajesh, Ketan, Md Danish, Umesh  Daksh.
The third group was G10; Jitender Singh, Alok Raj, Shubham Verma, Nitish Kumar, Archit Goyal.
These three groups will go to IIT Delhi (International Automobile Engine design championship) to represent SGI at Grand finale in March 2015.
Students learnt about the basic principles of Internal Combustion Engine and how it works. They also got knowledge about all different parts of IC engine and recent developments in the field of IC Engines. They also gained knowledge about alternative fuels used in IC engine.
These types of workshops are necessary for students because Industries are demanding skilled engineers and SGI fulfills this gap by organizing such type of workshops.
All the participants found this workshop very much useful and beneficial. All the participants were awarded with certificates, CD containing automobile videos, booklet and Catia Software.  Prof. (Dr.) Rajesh Goel, Director-SGI, motivated the students and the departments for organizing many such kind of workshops in near future.
