2. ABSTARCT
In many bikes , while running large
problems occurs like overheating of
engine , frictional losses so it becomes
necessary to analyze them.
This problems have adverse effect over
the viscosity of engine oil ,indirectly
affects performance of vehicle. Thus it is
very much necessary to eliminate it, and
can be done by effective cooling of
engine.
3. OBJECTIVES
The objectives of this project are:
1. To improve lubrication system.
2. To maintain the viscosity of engine
oil.
3. To increase heat dissipation rate.
4. To reduce the frictional losses in
engine.
5. To reduce the vibration in the
engine.
4. FUNCTIONS OF LUBRICANT
OIL
1. Keep moving parts.
2. Reduces the friction.
3. Transfer heat.
4. Carry away contaminants and debris.
5. Protect against wear.
6. Prevent against corossion.
8. PROCEDURE
First we took readings of temperature at
steady condition without system.
1. Steady condition – 0 km
2. Running condition – 40 km
Then by implementing our system
After setup , once again we took reading
1)steady condition – 0 km
2)running condition- 40 km
Then we compared reading of both
observations.
12. CONCLUSION
Thus we maintain the viscosity in the
engine by effective cooling and it
reduces the frictional losses ,vibration
and increases the heat dissipation
rate, the lubrication of the system
improves and Indirectly the
performance of bike Improves.
