Simulation on plateau power recovery of turbocharged diesel engine matched with electronic unit pump

Abstract

Aiming at the problem of power reduction of supercharged diesel engine equipped with electronic unit pump in plateau operation, a simulation model is established by using onedimensional software BOOST. Under the condition that the maximum combustion pressure and exhaust temperature are basically unchanged, the variation of maximum power, optimal injection advance angle and excessive air coefficient with inlet absolute pressure at typical speed is analyzed, which has important guiding significance for the control strategy of diesel engine in plateau operation.
