Hydraulic components in a transparent organic glass shell as the basic, working medium for hydraulic oil, white system at work can be clearly observed that the working process of the hydraulic components of the valve core, intuitive is strong.
The pressure transducer is directly exposed to the combustion chamber pressure when the spark plug is inserted. The spark plug itself retains its full functionality. For experiments using cylinder pressure indication on the test engine, the normal spark plug is exchanged for a modified spark plug. This modified spark plug is fitted with a micro pressure transducer. The pressure transducer is connected to the measuring amplifier in the electronic indication system. The core component of the pressure transducer is a heat resistant piezo-electric quartz crystal, which outputs a charge signal proportional to the pressure.
Learning Objectives/Experiments:
Cylinder pressure measurements on internal combustion engines.
The bench is trolley-mounted and has a front panel on which the control devices and all the instruments needed for the tests are located. The system includes two water coolers to cool the air generated by the compressor, complete with thermo-resistances for measuring the temperature of the air and water at the input and output. The Variable Speed Two Stage Compressor Study Unit With Digital Torque Indicator makes it possible to study the major characteristics of a twin-cylinder air compressor with two-stage compression.

The water finally flows back into the sump tank T1, the heat introduced into the system being removed by a water cooler, HE1. V2 simulates a vessel used for a hazardous process reaction, demanding the use of flame proof control equipment in its immediate vicinity, thus providing a logical reason for the use of pneumatic and interfaced control equipment. The process which forms the basis of operation of the various control loops and equipment is illustrated in. Water is fed to a centrifugal pump from sump tank T1 and then to a water heater HE2 before passing into two vessels V1 and V2, mounted in series and simulating a reactor system. Four standard areas of control are presented.
