MECHANICAL ENERGY STORAGE SYSTEM
•This system recoils a spring during braking and this energy is used to propel
the car when the engine is switched off.
•The spring is attached to the hub of the wheel, during braking the spring
gets engaged and coils as the speed decreases.
•When this lever is pressed the spring unwinds energy is transferred to the
wheels.
• This helps us recover energy during braking.

Current Status
1.The team has registered with two cars for the next year event.
•The Petrol Prototype will be a updated version of the 2011 car.
•The Electric Prototype will be based on the same platform and share most of its parts
with other prototype except the propulsion system.
2.We have completed the Technical Submission for both the cars.

Recap of the Year 2010-2011
•We were one among 6 Indian teams to be selected for the Shell Eco-Marathon
competition held in Malaysia.
•We were the best Indian Team at the event we all the static events .
•We were rewarded 2500 USD for our performance.
•We also developed a Chassis Dynamometer to test the vehicle’s performance
characteristics.

Chassis Dynamometer
•Chassis Dynamometer is an equipment which is
used to simulate road conditions.
•It is used to find the horsepower and torque at
the wheels of the vehicle.
•The equipment was designed and fabricated by
the team.

Electric Prototype
•Electric Prototype is being build to study the Plug-in
energy management system. This concept will help us
integrate systems for our 2013 urban concept.
•Specifications:
1.5 KW Brushless DC Hub Motor
48V 20 Ah Lion battery
Is mated to an on board energy recovery system
•The Urban concept will be based on the same
platform.

Ethanol Engine
Ethanol is used to power Internal Combustion engines world wide. As it is a non fossil
source of energy .This year we plan to develop an engine that runs on purely Ethanol.
Ethanol vs Petrol
Disadvantages of Ethanol
As the Calorific value of Ethanol is low more fuel needs to be burnt to
equal the energy produced petrol. Therefore 1.4kgs of Ethanol needs to
be burnt for 1 kg of petrol.
Ethanol Petrol
CV of 29700 KJ/Kg CV of 43000 KJ/Kg
Produces 1.5 kg of CO2 /Kg of Fuel Produces 2.4 Kg of CO2 /Kg of Fuel

Engine Modifications
•The engine is equipped with Electronic Fuel Injection System to control the
air/fuel ratio.
•The cylinder has to be lined with anti-corrosive lining such as molybdenum
oxide.
•The compression ratio has to be increased to increase volumetric efficiency of
the engine.
•We plan to run this engine on our urban concept.
CH3CH2OH + 3 O2 → 2 CO2 + 3 H2O + heat

MONOCOQUE DESIGN
•Monocoque is a construction technique that supports structural load by using an
object's external skin, as opposed to using an internal frame or truss that is then
covered with a non-load-bearing skin or coachwork.
•This helps us integrate the components better and ensure structural integrity.
•The components can be directly bolted on to the frame hence reducing material
weight and cost.
•Weight of the car can be reduced by a close 12 kgs.
•The possible materials considered are Fibre reinforced plastic or Carbon fibre.
