In order to improve the diesel engine performance under plateau (high altitude) conditions, a new Speed Adjustable Compound (SAC) supercharging method is proposed. A simulation model based on a six-cylinder V-type turbocharged intercooler diesel engine is built on the GT-POWER platform, and then simulation-based research is carried out. A genetic algorithm (GA) is used to identify the best oper...

The propulsion demands of high-speed naval vessels often rely on gas turbines, producing significant amount power achieving thus high performance requirements. Gas turbines can be used either to provide purely mechanical propulsion, or alternatively generate electricity, which is subsequently by electric drives propel the ship. However, thermal efficiencies are lower than those Diesel engines s...

The paper is aimed to create the mathematical model of centrifugal compressor based on group method data handling-type neural networks determine volumetric flow rate as dependence compressor’s technological parameters (the rotor’s angular velocity, inlet and outlet temperatures, pressures, atmospheric pressure). It important scientific task, because most compressors used in process industry don...

Abstract The electric supercharger can significantly increase the transient intake air charge of engine, thus increasing power output engine under heavy load conditions. However, traditional in-cylinder calculation model has calibration workload and low portability, is not suitable for supercharged gasoline engine. In order to reduce difficulty improve accuracy estimation, based on an this pape...

The structural fracture of the compressor blade is main cause fatigue failure. novelty this paper creative application bent swept-back modeling to turbocharger impeller. This based on a impeller satisfying k-ε turbulence model. A simulation model was established in ANSYS software, fluid–structure interaction calculated three models before and after improvement, results were compared analyzed. o...

Within a broader national project aimed at the hybridization of standard city car (the 998 cc Mitsubishi-derived gasoline engine Smart W451), our team tackled problem improving supercharger performance and response. The originally conceived design innovation was that eliminating mechanical connection between compressor turbine. In course study, it turned out is also possible to modify both comp...
