The four strokes are... Intake, Compression, Combustion, Exhaust.
Intake, Compression, Power and Exhaust
In a four-cycle engine, strokes refer to the four movements of the piston during the combustion process: intake, compression, power, and exhaust. These strokes work together to convert fuel into mechanical energy that powers the vehicle or machinery.
In a two-stroke engine, two strokes is one cycle. In a four stroke engine, four strokes is one complete cycle. A stroke is a part of a cycle. Remember that the "up" motion and the "down" motion each count as one stroke.
A two stroke engine combines the four strokes of a typical internal combustion engine into two strokes instead of four.
A four stroke engine has 4 strokes per cycle, whereas the two stroke engine has only 2 strokes per cycle. Since the 2 stroke engine has twice as many power strokes as a 4 stroke engine at a given rpm, the 2 stroke is capable of making nearly twice the power of a 4 stroke for a given displacement.
In a four-stroke engine, it takes 720 degrees of crankshaft rotation to complete one full engine cycle, as the cycle consists of four strokes: intake, compression, power, and exhaust. Each stroke corresponds to 180 degrees of rotation. In contrast, a two-stroke engine completes a cycle in just 360 degrees of crankshaft rotation, encompassing both the power and exhaust strokes in a single revolution.
Technician A is correct. The crankshaft must revolve two times to complete one cycle, which as 4 strokes. One half revolution for each stroke. Intake, compression, combustion, exhaust = four strokes to complete a cycle. One half revolution for each stroke of the piston going up or down. Look at a diagram and you'll see this is pretty simple.
A 2-cycle engine completes a power cycle in two strokes of the piston, while a 4-cycle engine completes it in four strokes. 2-cycle engines are simpler and lighter but less fuel-efficient and produce more emissions. 4-cycle engines are more complex but offer better fuel efficiency and lower emissions, resulting in better overall performance and efficiency.
The four strokes are intake, compression, combustion, exhaust.
A 4 stroke engine is also referred to as a four cycle refers to the internal combustion whereby the piston completes 4 separate strokes with a single thermodynamic cycle.
