FORMULA USED:

To determine the engine Torque

For 4 cylinder Engine

T=(weight) (arm length)= mg L

Where the arm length is 0.29 m

Brake power= 2*pi*NT/60000 (Kw) for four cylinder

Brake power= V*I/1000 (Kw) for single cylinder


22/23

Mass flow rate of fuel

= 10ml*density of fuel*10^(-6)/(time) Brake specific fuel consumption

= mass flow rate of fuel/B.P

A/F= mass flow rate of air/ mass flow rate of

fuel

Thermal efficiency= B.P*100/(mass flow rate

of fuel* CV)


23/23

Conclusion:

As the B.P reached its rated value th become

maximum and bsfc will be less.

Therefore it is not economical to run the engine

beyond its rated limit because the BSFC will increase

and thermal efficiency going decrease.

The Air-Fuel ratio become rich when the BP

increases.
