What is the first stroke in Otto's cycle?
Intake
Compression
Power
Exhaust
Answer
Intake is the first stroke in Otto's cycle, a four-stroke internal combustion engine cycle. During intake, the piston moves down the cylinder, creating a vacuum that draws air and fuel into the combustion chamber through the intake valve. This mixture is then compressed by the piston during the compression stroke, ignited by a spark plug during the power stroke, and finally expelled through the exhaust valve during the exhaust stroke.
