Test Cell Set-Up To Enable Drive-Cycle Testing Of A Variable Valve Actuation Enabled Camless Diesel Engine, Alexander Harrison Taylor
Open Access Theses
The previous facility which was used for engine testing at Purdue's Ray W. Herrick Laboratories utilized an eddy current dynamometer which is only suited for steady-state testing and throttle snaps. To better utilize a pre-existing camless diesel engine, which is is enabled via variable valve actuation, it was desired to perform transient drive-cycle tests. To accomplish this goal, a variable frequency drive AC dynamometer was required. Given that a brand new facility was constructed, the team was presented with an opportunity for ground up design of a test cell.
The new test cell's operation was proved out using a cammed …
