Introduction
The power out put of an engine depends upon the amount of air inducted per unit time and the degree of utilization of this air , and the thermal efficiency of the engine.
Indicated engine Power
IP=P*L*A*n*K/60000 ……………..(1)
Where, IP= indicated power (kW)
P=indicated mean effective pressure(N/m2)
L=length of stroke
A= area of piston
n= no of power stroke, for 2-s engine-N and for 4-s engine N/2, N= rpm
K= No of cylinders
