CT 100.13

- Cylinder pressure indication system, suitable for CT 100.20, CT 100.22 and CT 100.23 test engines


Technical Description

The system is used in conjunction with the CT 100.14 spark plug pressure transducer and the CT 100.15 respectively CT 100.16 pressure transducers. It allows pressure measurements to be carried out in the cylinder head of an internal combustion engine and is designed for the CT 100.20, CT 100.22 and CT 100.23 engines. The data is transferred to a PC for further processing. The software produces p-t and p-V diagrams, and also displays the mean pressure and the indicated power output. 

The system consists of an inductive TDC sensor, measuring amplifiers for the pressure transducer and TDC sensor and software.

Learning Objectives / Experiments

- familiarisation with and use of an electronic cylinder pressure indication system
- p-t diagram (top left)
- p-V diagram (bottom)
- pressure curve for gas cycle (top right)
- determination of indicated power output from p-V diagram
