EVOLUTION
In 1672, Ferdinand Verbiest invented the first steam powered car
Nikolaus Otto, Rudolf Diesel - pioneers of 4 stroke engines
In 1900, Ferdinand Porsche developed ec0-friendly hybrid cars.
In 1970's post WW-II due to fuel insufficiency, the eco-friendly took off into trend.
In 2000's, Many companies have come forward with Hybrid eco-friendly cars.
INTRODUCTION
Need for Zero Emission Vehicle
Battery manufacturing causes Lead Pollution
Pollution reduction by Nano-paints
The word Cryogenics stems from greek origin 'Kryos' meaning "Frost"
Thermal storage media used for automotive purposes, offering noteworthy performance and economy
WORKING PRINCIPLE
Fuel Tank contains LN2 @ 77 atm Pressure
Cryogenic Pump compresses to Operating Pressure
Pressurized LN2 passes through the Heat Exchanger
Gaseous N2 is then injected into the cylinder when the piston reaches TDC
Multiple Expansion strokes possible
Economizer uses exhaust gas to preheat the LN2.
THEORY

Efficiency ŋ= W/Q h =1- (T L /T H )
TL= 77K
TH= 300K
ŋ= 74%

COMPONENTS
Expander
Heat Exchanger
Cryogen Storage Tank
Expander
Basically a reciprocating piston type engine.
Rotary engines - high surface to volume ratio also suits.
Engine block to be kept as warm as possible - secondary fluid used
Power & torque controlled by throttling &cut-off of N2
Max power limited by heat transfer rate from atmosphere
Heat Exchanger
Cryogenic operation - Vaporizer capable of heating LN2 to ambient temperature on a winter day .
Long tube section of Al wrapped back & forth - capable of absorbing at least 75KW from atmosphere.
Electric fan - Passes through debris filter and particulate filter .
Inhibit ice build up - Teflon coating.
Cryogen Storage Tank
Resistance to deceleration forces
Minimum size, mass, and reasonable cost
Moderately high vacuum with super insulation
Titanium and Aluminum - Structurally reinforced dewar
Seven Day holding period.
What is Nano-Paint and Why?
A suspension of microscopic particles called nanotubes, that alter their behavior
Colour Changing
Scratch proof
Corrosion resistant
Self Cleaning
Toxicant absorbing
Controlled using a low grade magnetic field which is used to affect the spacing of the colloidal nano-crystals and there by controlling their ability to reflect light and change colour
Electromagnetic charge is needed to keep the desired colour active
The driver's mood induces colour change to the car.
ADVANTAGES OVER EV's
CHAMELEON CRYO CARS
OTHER ECO-FRIENDLY CARS
Easy to dispose
Non-Toxic
Engine Efficiency is about 74%
Lesser weight of engines
Operating cost is low (1km=1Re)
Batteries can't be disposed
Toxic in Nature
Engine Efficiency is 72%
Heavy weight engines
Operating cost is high (1km=2.4Rs)
Thus we are able to enjoy the benefits of the vehicle with the help of modern technology and preserve
MOTHER NATURE
Pollution free vehicle
