Today there was no official class for technology project. However Jal and I still went into uni as today finally the technician had put in the valve on the Mercedes common rail diesel engine. So is that we could get some pressure readings done for the exhaust system in the engine and see how it works and how the exhaust brake may affect these readings.
First we did tests at varying RPM's to get different pressure readings across the rev range without an exhaust brake. Then we did tests with the exhaust brake applied all the time and noticed a large increase in exhaust pressure on the manometer. Finally we did tests with the exhaust brake applied at engine overrun conditions and noticed the largest pressure readings which is good to see our projects concept actually works.
