Abstract
A two-stage turbocharging energy-efficient self-adaptive control method based on multi-point intake and exhaust pressures in diesel engine turbocharging field, including: determining a target turbocharging pressure for plains upon diesel engine speed and load conditions; adjusting it to obtain optimal target turbocharging pressures for varying altitudes; using these and measured multi-point pressures in intake and exhaust pipelines as inputs, based on an energy utilization analysis model, to determine the two-stage turbocharging energy utilization efficiency suitable for different altitude environmental conditions; according to the optimal overall efficiency principle of the two-stage turbocharging system at variable altitudes, calculating opening degrees of the bypass valves that meets the target total pressure ratio by a valve control unit. Reasonable distribution of exhaust energy between the two-stage turbochargers is achieved. The invention can achieve an efficient utilization of exhaust energy, and self-adaptive control of a variable-altitude two-stage turbocharging system.
