Advanced Technocracy Inc. is Manufacturer, Exporter & Supplier of Single Cylinder Engine w. Variable Compression

Technical Description

In conjunction with the test stand, the engine makes up a complete engine test stand.

Major technical modifications have been made to a standard water-cooled single cylinder engine to allow demanding issues in engine technology to be investigated by experiment. The key feature is that the cylinder has been modified so that its height can be adjusted along with that of the cylinder head. This allows the compression ratio to be adjusted over a wide range.

The engine can be operated as an external ignition petrol engine or an auto-ignition diesel engine. The mode of operation can be changed by a few simple conversion steps.

In petrol engine mode, it is also possible to change the ignition point and the composition of the fuel/air mixture so that the influence of these factors on the characteristic curves and values can be investigated experimentally.

Advanced Technocracy Inc. is Manufacturer, Exporter & Supplier of Exhaust Gas Calorimeter

Technical Description

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.
