A numerical simulation model for the sequential turbo charging (STC) diesel engine was established by STAR-CD and the initial boundary condition of the model was calculated by the GT-POWER. The experiment results were compared to multi-dimensional model results. Based on the model, the effects on the combustion process and the NOx emissions, including inject cone angle and inject timing were studied...
In order to accurately analyze the impact of gas flow in exhaust system on engine performance, the paper has set up 1D/3D coupling simulation model using GT-POWER and STAR-CD softwares based on TBD234V12 diesel engine. With the simulation result comparing with experimental data, the paper has proved the coupling simulation model is accurate. On the basis of using sequential turbocharging technology,...
Diesel engine is a complex system, and involves uncertainty with respect to parameter inputs and outputs. Grey theory is one of the methods used to study uncertainty, being superior in the mathematical analysis of systems with uncertain information. In order to find out the suitable turbocharging system for the diesel engine, grey decision making theory was used to evaluate different turbocharging...
Sequential turbocharging system is designed to enlarge the torque of diesel engine in part loaded conditions and reduce the brake specific fuel consumption. Hardware-in-the- loop simulation is a technology to design and test electronic controllers. In order to accelerate the development process and reduce the development cost, hardware-in-the-loop simulation was used to test controller of sequential...
