An indicator diagram is a chart used to measure the thermal, or cylinder, performance of reciprocating steam and internal combustion engines and compressors.
How do you find the area of an indicator diagram?
– The area can be measured by an instrument known as ‘Planimeter’ or by the use of the mid ordinates rule. [On modern engines this diagram can be continuously taken by employing two transducers, one pressure transducer in the combustion space and other transducer on the shaft.
What is Pcomp in engine?
Page 17. 2.4.6 Compression pressure (Pcomp) When the piston moves towards TDC, the air trapped in the cylinder will increase in both. temperature and pressure due to the decreasing volume.
What types of indicator diagrams do you know?
There are four types of indicator diagrams:
- Power card.
- Draw card.
- Compression diagram.
- Light spring diagram.
Why is PV curve an indicator diagram?
A curve showing variation of volume of a substance taken along the X-axis and the variation of pressure taken along Y-axis is called an indicator diagram or P-V diagram. Hence, in an indicator diagram the area under the curve represents the work done (Fig.).
How do you calculate power from an indicator diagram?
How to calculate power of Main Engine (2 stroke engine)?
- Power card or PV diagram can be used to measure indicated power in diesel engines.
- Calculations.
- Work done in one cycle = Mean Indicated Pressure x Area of the Piston x Length of stroke = [Pm] x [A] x [L]
- Indicated Power of Unit = Pm L A N.
How do I adjust my Pmax?
INCREASE IN Pmax IS ACHIEVED BY MOVING THE PIVOT VALVE TOWARDS THE LEVER. DECREASE IN Pmax IS ACHIEVED BY MOVING THE PIVOT VALVE AWAY FROM THE LEVER.
What is the size of the diagram of a 2 stroke engine?

How many types of indicator diagrams can be taken from engine cylinder?
There are 4 types of indicator diagrams that can be taken from the engine cylinder to know the condition and performance of the engine. Mean Indicated Pressure (MIP) is obtained from this diagram to calculate power produced in the cylinder
What is indindicator diagram?
Indicator diagrams give efficiency of combustion in the cylinder, condition of the running gear, irregularities in fuel pumping and injection and a lot of things. There are 4 types of indicator diagrams that can be taken from the engine cylinder to know the condition and performance of the engine.
What is a valve timing diagram for a 4 stroke engine?
As we all know in 4-stroke engine the cycle completes in 4-strokes that are suction, compression, expansion and exhaust , The relation between the valves (inlet and outlet) and piston movement from TDC to BDC is represented by the graph known as valve timing diagram.
