An exhaust gas calorimeter for use with Regenerative Engine Test Set. The equipment measures the heat content of exhaust gases and enables students to determine the energy lost to exhaust in the energy balance for single-cylinder, four-stroke petrol and diesel engines. The engines are separately available.
The main components of the Exhaust Gas Calorimeter are:
Instrumentation unit the heat exchanger is mounted on asxturdy base plate. Exhaust gases from the test engine mounted on the test set flow through the tubes. A jacket of constantly fl owing cooling water surrounds the tubes, and the heat content of the gases is assessed by measuring the cooling water flow rate and the inlet and outlet temperatures. A hand-operatedvalve, which mounts on the control console of the test set, controls the flow of cooling water through the heat-exchanger jacket. Thermocouples measure the temperature of gas and water at the inlet and outlet. A turbine flow meter measures the flow rate. For safety, the heat exchanger also includes a pressure are lief valve in case insufficient cooling water is fl owing.
