Turbocharging Matching and Control Strategy of Amphibious Vehicle Engine
Aiming at the power demand of amphibious vehicles under water and land working conditions,we carry out research on the power system supercharging matching and control strategy of vehicles under two work-ing conditions.A one-dimensional simulation model of a vehicle engine under two operating conditions was estab-lished,key components such as supercharger and bleeder valve were calibrated,and the simulation model of the whole engine was experimentally verified.Based on this model,the matching of the supercharging system under two working conditions is completed,the output characteristics of the supercharged engine under the amphibious working conditions are researched,and the control strategies for the opening of the exhaust gas bypass valve un-der the two working conditions are formulated.The results show that the computationally matched supercharger and control strategy satisfy the power demand of amphibious vehicles under different operating conditions.
