Calorimeter For Regenerative Engine Test Set

quick overview :

Description

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: • Gas-to-water shell and multi-tube heat exchanger • Control valve • Instrumentation unit The heat exchanger is mounted on a sturdy base plate. Exhaust gases from the test engine mounted on the test set fl ow 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-operated valve, which mounts on the control console of the test set, controls the fl ow 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 fl ow rate. For safety, the heat exchanger also includes a pressurerelief valve in case insufficient cooling water is fl owing. The instrumentation consists of a digital, four-channel temperature and fl ow display unit. This unit mounts on the instrumentation rail of the test set console frame and allows easy and accurate display and monitoring of data. In addition, the Exhaust Gas Calorimeter is fully compatible with Versatile Data Acquisition System .
