6. ENGINE TRANSMISSION
Honda Street 100 engine
4 stroke engine with single cylinder
Specifications: 97.2 cc, 6 bhp at 7500 rpm
Automatic centrifugal clutch with four forward speed
Provides a rear axle drive with the help of a chain and
sprocket mechanism

8. STEERING SYSTEM
Factors considered: vehicle weight, size, shape and
driving conditions
Steering which includes a Pitman arm with two tie
rod ends
100% Ackerman mechanism with an Ackerman angle
of 24 degrees
Fixed turning radius as 3 meters, for which rod end
travel was found as 0.127 meters

10. BRAKING SYSTEM
Choices available: Rim brakes and disc brakes
Rim brakes are cheap, light, mechanically simple,
easy to maintain, and powerful, they perform poorly
when the rims are wet
Brake pads can wear down quickly, have to be
replaced frequently and gets heated up
Disc brakes are more powerful and require less
maintenance. They provide a larger surface area for
heat dissipation. Hence, we choose disc brakes.

11. WHEELSSpecification for the tyres is 66 x 0.033 m
Wheel base of 1.41 m and a wheel track of 1.27 m to
provide better manoeuvrability and stability
Material to be used for
fabrication• 1018 steel pipes to use as our material for the
chassis
• Outer diameter of the pipes is 2.54 cm with a
thickness of 0.178 cm
• Total weight of 8.41 kg
• Readily available and easily weld-able with arc
welding

12. FE ANALYSIS OF CHASSIS
A frontal impact of 3-G force and a side impact of 2-G
force
different designs of the frame considering different
loads
factor of safety of about 1.8

14. HULL DESIGN
minimum volume of water to be displaced by hull
came out to be 0.3cu.metres
depth of the vehicle inside water is 0.5 metres
the hull has been designed by taking this volume as
0.6cu.metres

15. PROPELLER
Propeller is partly submerged in water and the axis of
the propeller is parallel to the rear axis
Propeller is fully submerged in water and the axis of
the propeller is perpendicular to the rear axle.
SEALANT
• Epoxies used as boat sealant costing about
Rs.500-600 per litre
• Silicon sealant in the form of a spray costing
about Rs.113/kg
• Hydrophobic rigid foam material

17. COST ANALYSIS
Total estimated cost = Rs. 19,650 (approx.)
Engine = Rs. 4000
Fasteners = Rs. 2000
Braking system = Rs. 2000
Wheels = Rs. 1500
Chassis = Rs. 1000
etc…
With appropriate financial support, the product and
its features can be vastly enhanced to make it
commercially viable.

19.  Social Media…
We are running a blog (www.kozamphicar.blogspot.com)
where we update all our work.
We are there in most of the popular networking social sites
like Orkut, Facebook (nitcAMPHICAR group) and Twitter.
In the future, we intend to popularize our work both in the
print and the electronic media.

20. Ranked in the top 15 technical institutes of the country.
 Tathva (starts 21st
October) is the second largest
techno-management festival in South India after IIT-
Madras.
Ragam, the cultural festival is the largest in Kerala
with performances by Shankar Mahadevan, Shaan,
etc.
A host of events and activities providing investors
and groups/firms to promote their products and
services throughout the year.

21. Platform (NIT-Calicut is one of the top-15 technical institutions) to
display expertise and knowledge in the technical field.
Visibility for individuals/groups who desire to make it big both in the
technical and financial sectors.
Team work ethics and coordination.
For the investor
If you are a technical expert and searching for that window to prove
yourself in society, here you are. You can provide your technical
expertise and we will promote you.
If you are willing to support us financially, you will have the
opportunity to promote yourself and your product/firm through us.
You will not only get visibility but also potential customers both in and
out of the institute.
