1. What is Work Done per Cycle in IC Engine?

Work Done per Cycle in IC Engine is defined as work done to push the piston downwards during the power stroke of the otto cycle in IC engine. It represents the useful mechanical energy produced in one complete engine cycle.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ W = \frac{P \times nR}{E_{rpm}} \]

Where:

\( W \) — Work Done per Cycle in IC Engine (Joule)
\( P \) — Indicated Engine Power (Watt)
\( nR \) — Crankshaft Revolutions per Power Stroke
\( E_{rpm} \) — Engine RPM (Revolutions per Minute)

Explanation: This formula calculates the work done during one complete engine cycle by relating the indicated power output to the engine's rotational speed and the number of crankshaft revolutions required per power stroke.

3. Importance of Work Done per Cycle Calculation

Details: Calculating work done per cycle is essential for understanding engine efficiency, performance analysis, and comparing different engine designs. It helps engineers optimize combustion processes and improve overall engine performance.

4. Using the Calculator

Tips: Enter indicated engine power in watts, crankshaft revolutions per power stroke, and engine RPM. All values must be positive numbers greater than zero for accurate calculation.

5. Frequently Asked Questions (FAQ)

Q1: What is indicated engine power?
A: Indicated engine power is defined as the power that is produced in the cylinder of an engine as a result of the combustion of fuel, measured before accounting for mechanical losses.

Q2: How are crankshaft revolutions per power stroke determined?
A: Crankshaft Revolutions per Power Stroke is defined as the number of crankshaft rotations when the IC engine takes one complete cycle, typically 2 for four-stroke engines.

Q3: What is the typical range of work done per cycle?
A: The value varies significantly based on engine size and type, but typically ranges from a few joules for small engines to thousands of joules for large industrial engines.

Q4: How does this relate to engine efficiency?
A: Work done per cycle is a fundamental parameter in calculating indicated thermal efficiency and comparing the effectiveness of different engine designs and operating conditions.

Q5: Can this calculation be used for both diesel and gasoline engines?
A: Yes, this formula applies to both diesel and gasoline internal combustion engines, as it calculates work based on fundamental power and rotational parameters.
