Exhaust Gas Calorimeter.
Exhaust Gas Calorimeter
Determination of the thermal
exhaust gas losses is essential when calculating an energy balance for
internal combustion engines. Calorimetric measurement is an established
method of doing this. It involves a largely complete and loss-free heat
exchange between the exhaust gas and a cooling medium.
The
exhaust gas calorimeter consists of an insulated stainless steel tank,
through which the exhaust gas flows from bottom to top. While doing
this, the exhaust gas gives up its heat almost completely to a finned
pipe with cooling water flowing through it. The pipe is arranged in
loops to achieve the maximum possible heat exchange area. Relevant
temperatures (water and exhaust gas inlet and outlet) and the volumetric
flow of the water are recorded electronically and displayed digitally
using a measuring amplifier. The measuring amplifier is connected to the
test stand using a data cable. This allows the measured data from the
to be stored and processed using PC data acquisition.
