An exhaust gas calorimeter for use with Regenerative Engine Test Set. The engines are separately available. 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 main components of the Exhaust Gas Calorimeter are:
Control valve
Gas-to-water shell and multi-tube heat exchanger
Instrumentation unit the heat exchanger is mounted on asxturdy base plate. A hand-operatedvalve, which mounts on the control console of the test set, controls the flow of cooling water through the heat-exchanger jacket. Exhaust gases from the test engine mounted on the test set flow through the tubes. A jacket of constantly flowing 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 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 flowing. Thermocouples measure the temperature of gas and water at the inlet and outlet.
A versatile regenerative enginetest set with comprehensive controls and instrumentation. When used with one of optional single-cylinder engines, it safely and effectively enables study and demonstrations of the features and characteristics of the engine. Using this enables accurate real-time data capture, monitoring and display, calculation and charting of all relevant parameters on a computer making tests quick and reliable. In addition,optional ancillaries are available to extend the range of study, demonstrations and investigations even further. The equipment is fully compatible with Versatile Data Acquisition System.
The main components of the system are:
A fuel tank support frame that supports the fuel tank and optional fuel gauge
A heavy fabricated floor-mounting bed
An instrument console with instrument frame
The bed is held on anti-vibration mounts. It includes a robust trunnion-mounted d.c. machine. When the engine is initially mounted onto the test bed or exchanged with an alternative engine, dowels and slots locate the engine quickly, accurately and reliably. An electronic load cell connected to the machine measures the driving torque of the test engine. The engines are supplied pre-mounted on a sturdy precision base plate. Each engine includes a colour-coded fuel tank with self-sealing couplings.
Safety Features:
Emergency stops on test bed and console
Interlocks for mains power failure and engine over speed.
