The invention discloses a multi-state parallel supercharging system. The multi-state parallel supercharging system comprises a plurality of superchargers, an intercooler, an engine and an ECU, wherein the plurality of superchargers are connected in parallel. The intercooler is connected with the plurality of superchargers through a first pipeline. An air inlet of the engine is connected with the intercooler through a second pipeline, and an air outlet of the engine is connected with the plurality of superchargers. The ECU is electrically connected with the plurality of superchargers, the intercooler and the engine, and the ECU controls the working number and the working state of the plurality of superchargers by reading parameters of the engine. Therefore, for the multi-state parallel supercharging system, automatic electronic control can be realized, and meanwhile, the optimal performance of all working conditions of the engine can be realized.
Description
technical field [0001] The invention relates to the technical field of engines, in particular to a multi-state parallel supercharging system. Background technique [0002] Because the turbocharger belongs to the turbomachinery, compared with the reciprocating internal combustion engine, it has the disadvantage of narrower efficient operation range. The matching of the supercharger is difficult to have good performance in the full range of engine operating conditions. In order to improve the performance of the engine in all operating conditions, researchers at home and abroad have proposed many advanced supercharging systems. [0003] At present, marine engines have different operating conditions in different regions and different operating conditions. High-power marine diesel engines mainly match turbochargers according to the common operating conditions of different customers, so as to meet their performance and emission optimization. , This technical route will cause the ...
