DCE’s HYBRID CAR
Students of DCE unplug their potential by designing the First Hybrid Car of India. A student team of DCE has designed and developed a gasoline-electric hybrid car for participation in Annual Green Car Festival organized by North East Sustainable Energy Association of USA in May 2006. The first hybrid car of India was flagged off by Smt. Sheila Dikshit, Chief Minister of Delhi today, April 27, 2006 from her residence. Dr. Deepak Pantal, Vice-Chanccellor of Delhi University was also present The DCE hybrid car, code named 'The Fledge', is a combined effort of seven students of DCE and is an attempt to propel India in the arena of Hybrid Electric Vehicles (HEVs), and portray the innovative and creative genius of the youth of our country. ' Necessity is the mother of all inventions' and the mounting burden of petroleum prices on the common man has kindled a spark in the DCE students to unearth this new technology with a revolutionary drive train said Abhishek Agarwal, the team leader. Power transmission in the DCE Hybrid Car occurs on the engine as well as on the motor mode providing the user with an option of switching to either mode at any point of their journey. A powerful 18BHP, 346cc engine along with a 3.5HP, 3000 rpm permanent magnet DC motor serves the very purpose. Falling in neither category of series or parallel hybrid cars, the DCE Hybrid employs its customized drive train incorporating less complex components and hence being more efficient. A 200Ah lead acid battery with a 13 lt fuel tank provide with the Energy storage system.
The DCE hybrid is a green car with near zero emissions in urban driving conditions. The vehicle can be made commercially viable as besides being fuel efficient it will also be affordable to the common man. Its potential will be showcased at an international level competition 'TourDeSol' while competing with 55 other participants. With 'The Fledge' we hope to open a new dimension to the burgeoning automobile industry of India. Success, however, is never a matter of luck or genius. Two years of indomitable commitment and determination paved out path to success. The student team comprises of Abhinav Bhatia, Abhinav Duggal, Abhishek Agarwal, Anubhav Jain, Ashish Dudani, Nitesh Gupta and Siddharth Arora, all 6 th semester mechanical engineering students. Applauding the efforts made by DCE students and faculty in designing and developing the Hybrid Car, Smt. Dikshit said that design innovation of Hybrid is the technology solution to the twin problems of environmental pollution as well as an alternative to the gasoline vehicle. The vehicle being noise less and pollution free would provide to Indian metros such as Delhi a viable transport vehicle for the roads. Smt. Dikshit desired that DCE alongwith its auto industry partner should make it possible to mass produce such a vehicle for the roads of Delhi. The vehicle will also be highly suitable for use in zero tolerance areas such as large hospital campuses, airports, and large institutional campuses such as IIT's, DCE and University Campuses.
SUPER MILAGE VEHICLE
The strong demand for non-renewable resources coupled with importance of transportation has greatly accentuated the need for fuel efficient vehicles. In addition to that escalating fuel costs further bring the problem in limelight. In the era where vehicles are now available as commercial products from original equipment manufacturers, consumers today have grown smart enough to explore their options from a relatively competitive market. This is where manufacturers strive for mileage. The SAE-Supermileage competition is a student design competition organized by the Society for Automotive Engineers (SAE-International).The competition provides engineering and technology students with a challenging design project that involves the development and construction of a single-person, fuel efficient vehicle. Students have the opportunity to set a world fuel economy record and increase public awareness of fuel economy. The vehicles must be conceived, designed and fabricated by the students without direct involvement from practicing engineers, faculty or professionals from the racing community, and the team must be equipped to explain and justify their design.
The event, supported by various corporate giants from all over the world is held in various parts of the world, including Marshall, Michigan (U.S.A) annually. The best teams from around the globe put their engineered vehicles to test and fight for the top awards. The competition has been witnessing record mileages being attained by the frontrunners, thus setting higher benchmarks for new entrants as well. Delhi College of Engineeering (DCE) occupies a pivotal position in the matrix of technical schools in the country, imparting sound technical education to its students. This ensures that the students, right from the rudimentary stages of their technical education develop an inquisitive temper and are exposed to the latest technologies, thus motivating them to take up challenges in their fields. The Delhi College of Engineering Student team was the first ever team from Asia to participate in the competition in 2005 and won laurels.
UNMANNED AERIAL VEHICLE
The scale and suddenness of the 7/11 tragedy has brought back into focus the country's need for effective surveillance. While India is yet to develop its own technology for stealth surveillance through unmanned aerial vehicles (UAV), Delhi College of Engineering (DCE) has developed a laboratory-level model, weighing 1.8 kg and capable of lifting 28 kg weight.With a light-weight carbon frame, the vehicle is equipped with surveillance cameras, wireless sensors and vision-processing software. It is capable of operating both on the ground and in air.The complete vehicle comprises twin UAVs, one large and one small. The latter is positioned on the former during launch and later takes off from the orbiting mother UAV after a pre-determined height.The team has been worked on the project for close to 18 months. The departments that have been involved include mechanical engineering, computer engineering, industrial engineering and electronics and IT.Says Dr. M. Kulkarni, head of the department of IT, who was one of the faculty members associated with the project: "This is a working lab-level model, but much more advanced than a prototype. The basics of the technology have been mastered and our ultimate aim is to share it. The vehicle hardware and control systems, both developed in the college, enable the vehicle to travel to destinations specified by GPS waypoints, use artificial vision to locate and identify target buildings and conduct stealth surveillance. It is also equipped with obstacle-avoidance technology through SONAR sensors.
"Right now the vehicle flies only at a height of 15 to 20 feet, but with increase in the power of the engine, a height of 100 to 200 feet can be easily achieved. It is ideal for surveillance, though this particular version was made keeping in mind just the competition specifications," Dr. Kulkarni said. The wireless network between the secondary vehicle and the base station has been tested successfully for a distance of 3.5 km, sending online pictures and information. The vehicle uses high-efficiency motors and electronic speed controllers.
It supports all services like wi-fi, wipe, camera support, LAN etc. Fully featured Network Management can be used on BPL with all services from chat to video conferencing.
For testing purpose BPL technology is applied in a Alipur Village within a radius of 1km where the whole village is connected via BPL technology and the network facility can be used anywhere through power plugs. It is operating successfully with no problems till date under very hostile conditions.

CHANDRA RATH
The “CHANDRA RATH” is uniquely designed and developed in such a way that it can navigate all type of terrains on the moon surface. The design consists of three parts in which front and the rear part absorbs all the shock keeping the middle part almost stable. The design can also be very useful for developing the most comfortable car. The size of the “CHANDRA RATH” can be reduced to three fifth of its total length in a very less time. It is our great honor that “CHANDRA RATH” participated in the GREAT MOONBUGGY RACE organized by NASA and US space and rocket centre in USA. The purpose of this competition is to build a compact, light, flexible and durable vehicle that would carry astronauts on moon’s surface during Apollo Missions. Team “CHANDRA RATH” was the first entry from Asia to participate in this prestigious competition. The vehicle is supposed to be human powered and later on will be converted into solar powered and hybrid vehicle capable of traversing all kinds of terrains. The track which is designed by NASA and U.S Space and Rocket center consisted of seven tenth of a mile of lunar surface composed of craters, rocks, lava, inclines and “lunar” soil. Every part of the vehicle had been indigenously designed and built with utmost care.Special features of the moon buggy include: Steering mechanism, Suspension, Disc Brake, Shockers on each part for maximum stability and control, Folding capabilities for making the buggy fit into a 64 cubic feet volume box.The team flagged off to USA earlier this year.
GPS navigation ground vehicle
Students of Delhi College of engineering doing their training in DRDO made a GPS navigation ground vehicle which is capable of transporting 15kg-20kg of weight at a time. It is a four wheel independent DC motor drive. It hosts a central microcontroller interface which receives coordinates and commands from the central server and divides the information to other parts required for working of the task. MAP is installed over the server and the vehicle receives information of path from there. It has a rechargeable battery which is used for the functioning. Cost of the prototype is Rs. 27000 to Rs. 28000 but it will be reduced by 30%-35% if manufactured on large scale and also its capacity of carry weight can be increased.
Wind Energy System
Fuel shortage and high price is giving rise to new invention of energy sources. A project on wind energy system is submitted by B. Suresh, final year student of Masters of Engineering, Delhi College of Engineering. Two research papers are under publication under IEEE a leading society of electronics and electrical engineering. Wind Energy System uses voltage control and frequency control method to produce energy.
This project is proposed of using indirect current control for maximum power driving. This current control technique is new and has not been used yet. This control strategy is faster and efficient over voltage control technique.
