Testing and Results
The requirements were that the dynamometer had no observable deflection, the requirement the next test was that the engine produced 35 horsepower when loaded by the dyno, and the requirement of the last is there is no run out on the output shaft of the engine being tested, these parameters of interest (horsepower and mm or inches of run out and deflection). The predicted performance is as follows, the engine should produce 35 horsepower, the deflection of the dynamometer is less than 1/8th of an inch, and the run out test should have no more than 5 thousandths of play. To acquire this data an accurate ruler will be used to measure the deflection of the dynamometer.
For the horsepower run, the engine dynamometer will be used in correlation with the attachment that was engineered to take the deflection out of the system and recover lost horsepower. The run out test will use a dial indicator which will tell if the bearing is pressing down on the output shaft. Scheduling the testing was a problem because the testing portion came faster than anticipated, the testing got pulled back to the 3rd and 4th week of the quarter. According to the schedule the setup for all equipment, run the dynamometer, take pictures, and fix any arising problems would take around an estimated 17.5 hours and actually took around 17 to fully prepare everything.
