Parallel sequential turbocharging systems are able to operate in different modes, which are defined according to the turbochargers
that simultaneously boost the engine, and are controlled by means of specific valves. In order to cover the full engine operating
range, a smooth transition between turbocharging operating modes must be ensured. However, important disturbances affect both
boost and exhaust pressure when shifting the operation mode, thus causing non-negligible torque oscillations. This paper presents
different methods for smoothing such undesirable effects during mode transition. Strategies covering optimal synchronization
of the control valves, control of the valves’ position, and correction of the injected fuel during the transition are analysed.
A fully instrumented passenger car engine is used for illustrating the different torque smoothing methods, and experimental
results for transitions during both steady operation and engine accelerations are shown. 相似文献
