Auto Technician A says during the power stage of engine operation, the piston is forced downward in the cylinder due to the comp
ression of the burning air-and-fuel mixture. Auto Technician B says the power stage of engine operation is directly followed by the intake stage. Which one of the following statements is correct? A. Both Technician A and Technician B are correct.
B. Neither Technician A nor Technician B is correct.
C. Only Technician B is correct.
D. Only Technician A is correct.
<u>Option-(B):</u><u>Neither Technician A nor Technician B is correct, As the whole process does not follow the Otto cycle.</u>
Explanation:
<u>Engine Operation:</u>
The engine operation occurs in four main stages, as its function of any four-stroke engine requires the crankshaft to rotate twice in the machine covering about 720° degree of rotation while on its position.
<u>While, the four main stages for the engine to operate are as follow:</u>
<u>Intake:</u>The fuel is injected inside the piston.
<u>Compression:</u>As during the compression the volume is decreased and as more energy is released due to this phase of the engine.
<u>Power: </u>During the power stage the expansion of the gases which are compressed before are expanded, providing a power stroke to the engine.
<u>Exhaust:</u> The phase during the engine cycle in which the air is exhausted out from the combustion chamber of the engine.
