Figure of Dynamometer
A dynamometer is basically a device for delivering an effective comparison or analysis of an engine output or performance. Dynamometers are a lagging indicator, which means that the dyno only tells you what has happened during the dyno run or test period. After you apply your best engine building skills, dyno serves the purpose of evaluating the engine's capabilities over a specified period of time.
A dynamometer primarily measures horsepower, torque, rpm range over which the engine was tested, temperature and air flow.
Some dynamometers measure the level of exhaust and intake pressure, the noise level of the fuel flow.
The top racer owns a dyno, as it is a very powerful tool. It provides valuable information about the performance of transposed engines in a set of graphs. As dynamometers measure engine output, separate and measure the matrix of horsepower and torque, they are very useful for detailed performance tests.
There are certain metrics in preparation for a dyno test that you should have or should have before planning a test. These include minimum horsepower, gear ratios if you are not attaching a water brake to the output shaft of the motor.
A good dyno allows the user to enter today's environmental or altitude conditions. When reporting, the software provides correction factors so that each day is measured because it was the same as the previous time that the engine was tested or for a set baseline so that you always get a set comparison.
Dynamometers are very handy and useful, but they are very expensive devices. Many of them are also small noises, even when they are running on small motors. The exhaust is caustic and, therefore, dinos should only be used in properly ventilated areas.
Before investing in a dynamometer, some aspects must be considered, such as the size of the work space, the possibility of storing volatile fuel, or access to certain utilities such as the proper water supply for water breaks.
A computer and a color printer are also required for recording and monitoring the way the engine performs.
When the requirements are met, all it takes is investing the right time for ambition, dedication and refinement.
