Study on Intake Performance of Camless Engine

Abstract:

Electromagnetically-driven valve (EMVA) represents one of the most important developments in camless engines, which can realize unthrottled load control. An AVL-BOOST simulation model for a camless engine equipped with EMVA is built up and validated by the experimental results. The performance of the camless engine is simulated, and the intake performance and pumping loss are determined. The results of research show that the mass flow of the camless engine can be controlled by changing the intake valve opening duration, so that the load is controlled. They also show that the pumping loss can be reduced and the fuel economy can be improved during part load.
