Question
Chapter 18, Problem 1RQ
To determine
Mention the strokes of a four-stroke cycle.
Expert Solution & Answer
Explanation of Solution
The engine cycles are determined by the total number of piston strokes needed to finish the cycle. During each stroke, the crankshaft completes rotation of
The strokes of the four-stroke cycle are as follows:
- Intake stroke.
- Compression stroke.
- Power stroke.
- Exhaust stroke.
