A commercial CFD code is used to calculate a complex engine coolant flow in a poppet-valved type two-stroke gasoline engine. A simple design analysis method solving a coolant flow only in a cylinder block is suggested to effectively analyze flow distributions. The cylinder head geometry is modelled as a simple plenum chamber box so that a design analysis time can be shortened greatly. Even though detailed flow behaviours in an actual cylinder head cannot be analyzed, the important design parameters, such as flow rates through cylinder head gasket holes and flow distributions in the water jacket of a cylinder block, can be analyzed effectively.<br/>

This paper describes a simulation of secondary motion of piston assemblies using PISDYN by Ricardo. Motions of the piston, pin, rod and skirt are separately calculated, by integrating equations of motion for individual components and dynamic degrees of freedom. The effects of engine speed at full load and pin offsets on the piston assembly secondary motions, forces and friction were investigated in parametric study for 4-cylinder gasoline engine. Results show that lateral displacement and friction loss of the piston increase as a function of engine speed. The lateral motion of the piston is affected by the change in pin offset. The minimum friction loss for the condition of 4800rpm WOT occurs at a pin offset of 1.6mm.

This paper describes modeling and simulation of automotive forward collision warning and avoidance system using CASE(Computer-Aided Systems Engineering) tool. The system is composed or many sensors, a controller, warning devices, brakes and etc. The system was modeled by one activity chart, fourteen state charts and one module chart. Rear-end collision scenarios was generated by Simulink and used to support Stalemate model. The resulting model was used to evaluate the correctness of function and behavior of the system. A simulator for the system has been designed and used to validate the model under realistic operating conditions in the laboratory. To model and simulate the system's functionality and behavior brings clarity to system design early in the system development.
