DYNO TEST CELL INFO
- Engine test comes at the end of many hours of painstaking work.
- It is the acid test.
- It is vital to be honest about the result.
- If an engine on test is a prototype, and if the test schedule is in fact a development programme, it is vital to analyse and learn from the experimental results in order to be on an improving trajectory.
- Most engines of all sorts require some degree of troubleshooting. That is what we try to excel at.
- We have a mantra: The answer is always easy, once you know it!
- The simplest test involves installing the engine on the test bed, running it in on a medium load, running it at full power up the rpm range, recording rpm, brake load, horsepower = rpmxload/600, oil pressure,fuel flow, coolant temp in and out, oil temp in and out, correction factor + or – 1 or 2%, corrected bhp = actual observed hp x correction factor, specific fuel consumption pints/hp.hr or grams/kw.hr, exhaust temp, air temp, ignition advance…
- If the engine is in perfect mechanical order and if all the figures are in the right ballpark and in line with expectation, then the test is pronounced satisfactory.
- Otherwise, we start troubleshooting.
- Prior to an engine test, there are lots of unanswered questions. The test is all about answering those questions. How much power will it give? How much fuel will it use? Will it hold together? Will it overheat? Will it maintain oil pressure? Will it suffer from detonation? Will it run to its maximum rpm without valve bounce? Will it burn oil? Will it leak oil or coolant? Will it have excessive crankcase pressure?
