A turning moment diagram for a four stroke cycle internal combustion engine, we know that in a four stroke cycle internal combustion engine, there is one working stroke after a crank has turned through two revolution i.e.7200 . Since the pressure inside the engine cylinder is less than the atmospheric pressure during suction stroke therefore a negative loop is formed. During the compression stroke, the work is done on gases, therefore a higher negative loop is obtained.
2 Velocity and acceleration in Mechanisms (17412)
i) Velocity of crank AO:
VAO = (r X ω ) X (480 X 20)
aab = l(ab) X Scale = 4.3 X 40 X 103
aab = 172 X 10 mm/sec2
