Abstract
1D system simulation is now well deployed over the engine development cycle, especially for engine and component design. 1D codes have been used for years in two very distinct areas: for the simulation of gas dynamics in the air path in order to evaluate engine performance, and as a support for the design of the actuators allowing the connection of hydraulic and pneumatic, mechanical and electrical components.
During the engine integration stage, the set-up of the actuator on the engine and the calibration of the associated control strategies are generally achieved on the test bench, which leads to a time and cost consuming process. The use of a dedicated model for the analysis and optimization of the integration of the engine actuation system represents a real added value. Being able to assess the first steps of the calibration of the control strategies in a virtual environment makes it possible to significantly reduce the time and cost when compared to conventional testing approaches.
This paper aims to illustrate the capabilities offered by 1D system simulation to cover a broader range of the engine development cycle, from detailed engine design to actuator and control integration. A proof-of-concept completes the theoretical methodology, detailing a practical application of a variable valve actuation system. The model developed includes the intake and exhaust systems, the VVT actuator, the combustion chamber and a first level of control strategy. The objective is to simulate the impact of the valvetrain control strategies on the engine breathing and the combustion process.
