Involvement of Dynamometer Reading veryone who has something to the message. In these circumstances it is very difficult to manually register all the information. Reliable data collection computer is now considered to be necessary in the engine builders and testers. Today it is possible that the registration, control and playback capabilities palm size package, which many years ago, it cost much more, and had the same size as a refrigerator. Adequate system of data collection computer must be equipped with very fast sampling rates. To ensure the quality of data, you must be at least 100 samples from all sensor channels per second (100Hz). A capitalization rate of 200Hz or more is even better. It is important to realize that the spark plug firing, there is a limit torque and speed, which can be measured. Korbowego is faster shortly after combustion occurs, and then it slows down until the plug again to shoot. It is not possible for the rapid UPS and downs when you are on the track or road, but it will be. In this connection, there is a 200 Hz log price data system for the trick, as well as appropriate the dynamometer. But if you try to only 50 Hz, you should consider the introduction of a single rpm, torque and examining the data, each revolution. From time to time, a number of tests will be synchronized with the firing of studying, and sometimes samples of data will be synchronized with some minor power compression stroke. If you have a fast and reliable system to follow each cycle a few times, so that data can be used by the average of the phenomenon. Average data is a very important step in the data. During this time, and experienced players dynamometer see a similar power curve in the two graphs, Dyno inexperienced traders expect a smooth, clearly liner. The reason why the average and the ability to mitigate the information that is critical for the acquisition is that it do not have to deal with so many prints. For example, at 100Hz, you will get 1,000 rows of data on more than ten seconds dynamometer draw. You can choose not to look for small changes in the dozens of pages of data each time you need to prepare for another run. Averaging removes both transient noise and bright print, and it is very useful in the process of recording data from the insurgency. |
