The Simulation, Implementation and Analysis of the Miller Cycle Using an Inlet Control Rotary Valve

This paper describes the application of a variable-phase I.C.R.V. to a modern 4-valve automotive engine with electronic fuel injection and lambda feedback control. Some of the difficulties associated with applying an I.C.R.V. to this kind of engine are discussed. Performance and emissions data are presented for both the baseline (throttled) and I.C.R.V. configurations, and the data compared with predictions from a computer simulation.
