CT 159.01

- Cylinder pressure indication system, suitable for CT 150 - CT 153 test engines


Technical Description

Indicating systems can be used for a thermodynamic analysis of engines. In industrial applications, these systems are used to optimise the combustion process.

The system is used in conjunction with the transducer sets CT 159.03, CT 159.04 and the CT 159.05. Each of the sets consists of a pressure transducer and a TDC sensor. It allows pressure measurements to be carried out in the cylinder head of an internal combustion engine and is designed for the CT 150, CT 151, CT 152 and CT 153 engines. The data is transferred to a PC for further processing. The software produces p-t and p-V diagrams, and also displays the average pressure and the indicated power output. 

The system consists of software and a measuring amplifier for the pressure transducer and TDC sensor.

Learning Objectives / Experiments

- familiarisation with and use of an electronic cylinder pressure indication system
