SI Targets 2012
1 To achieve 500 Kmpl
2 To compete at Shell Eco Marathon Malaysia
3 To Build a platform to develop and test propulsion systems-Ethanol & Electric
SI Targets 2013
1 To build an Urban Concept Vehicle
2 Meant for road worthiness.2 seater and 4 Wheels
3 Target to reach 300kmpl
4 Propulsion by Ethanol and Electric
Shell Eco Marathon provides us the ideal platform to achieve these dreams

Garuda 2012 Prototype- Gasoline•The 2012 car will be an optimized version of the 2011 car.•We have been testing the car for the last few months have proposed changes in the following systems.
System Issues Measure Analysis Implement Design Changes
Target
Transmission Chain Popping off
For every 3 Kms pops off 1 time
No Tension on Chain
Chain Tensioner
New Transmission System
Chain Shouldn't Pop
Steering Turning Radius of 9mts

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 Motor48V 20 Ah Lion batteryIs mated to an on board energy recovery system
•The Urban concept will be based on the same platform.

Ethanol EngineEthanol 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.
