Abstract

The invention relates to the technical field of engine devices, in particular to a turbocharger electric control adjustable blade diffuser device and a control method thereof. The turbocharger electric control adjustable blade diffuser device comprises an adjusting mechanism, a gas compressor and a fuel gas inlet shell; the adjusting mechanism comprises a middle body, a driving assembly, a transmission assembly, blades and a pressing plate; the fuel gas inlet shell is connected with a diesel engine; and the driving assembly on the middle body drives the transmission assembly to drive the blades to rotate, so that the relative position of a combined operation line of the turbocharger and the diesel engine relative to the performance surge boundary of a turbocharger compressor is adjusted when the blades rotate, the problem that when the operation working condition of the diesel engine deviates from the rated working condition, surge can affect the operation reliability of the turbocharger is solved, and meanwhile, the effect of optimizing the matching performance of the turbocharger can be achieved to a certain degree.

Description

technical field [0001] The invention relates to the technical field of engine devices, in particular to an electronically controlled adjustable vane diffuser device for a turbocharger and a control method thereof. Background technique [0002] As one of the important parts of the diesel engine, the compressor of the turbocharger plays a vital role in the operation of the diesel engine. [0003] A sign of a good match between the turbocharger and the diesel engine is that the combined operation line is in the high-efficiency zone of the compressor performance curve and has sufficient surge margin, while the diesel engine's fuel consumption rate, exhaust temperature and other performance indicators are in an ideal state. [0004] However, when the operating condition of the diesel engine deviates from the rated operating condition, the matching joint operation line of the turbocharger and the diesel engine will deviate, and the matching performance of the diesel engine may bec...
