AIr volume tester (engine pistons, combustion chamber, cylinder head, transmissions,or other)
Do you have to control accurately on the production line the volume of an internal combustion engine combustion chamber?
Would you like to make sure that the dispensing machine put the right level of oil in your refrigeration/AC compressor or your transmission case?
Would you lack to control your fluid levels faster on the production line?
Do you want to make sure that you filled a bottle at the right level, quickly
on a production line?
ATEQ has been by consulted by internal combustion engine manufacturers in order to find a solution using air to test accurately and fast the volume of a combustion chamber on the production line. A combustion chamber too large would reduce the compression rate of the engine and make a weak explosion, and a combustion chamber too small would increase the compression in the engine and create early ignition problems.
The test methods they had investigated were using liquid to measure the volume of this complex shape but crucial component of the engine, because the shape was too complex for an easy dimensional gauging. These liquid measurement methods were accurate in a laboratory but could not be used on a production line for 100% testing. They wanted a dry test to detect an out of tolerance piston or cylinder head before it would be assembled in an engine.
That's why ATEQ originally developped a high speed accurate volume tester using air.
Since then other problems were solved using the same technology, like the liquid level in an engine transmission. In an engine transmission, you want to make sure that all the components are in contact with the fluid. The traditional method was to weigh the transmission before filling it with fluid, measure the amount of fluid put into the transmisson with a mass flow meter, and control the weight of the transmission after adding the fluid. Unfortunately some transmissions were returned for lack of fluid when measured at the dipstick.
They realized that no matter how accurate the weight of liquid in a transmission is measured, the dimensional tolerance on the housing and assembly was such that some components on top of the transmisson could end up without fluid. What they wanted to guarantee was not an accurate quantity of fluid, but a level of fluid.
To verify the liquid level of every transmission with a dipstick was too labor intensive so they came up with the idea of measuring the remaining air volume on top of the tramsmission after filling, which they did succesfully with an ATEQ Votuteq high speed air volume tester.
Manufacturers of reciprocating(piston) compressors solved their oil level problems in the same way which was faster than the double weighting they did previously.
The ATEQ Voluteq was developped on the same proven hardware basis and rugged hardware components used by the other ATEQ quality control instruments (leak and flow testers), so the spare parts are readily available in ATEQ service offices worldwide.
So if you have a high volume production with internal cavities whose volume need to be tested fast and accurately, like an automotive transmisson, this technology could be interesting.
