Abstract

This project focuses on the design and validation of a camless engine valve system as an  alternative to traditional camshaft-based valvetrain architectures. Conventional engines rely on  fixed camshaft profiles that limit performance and efficiency across varying operating  conditions. The goal of this work is to replace both the camshaft and throttle body with a  pneumatically actuated system capable of independently controlling valve timing, lift, and  duration in real time. By removing the mechanical constraints of a camshaft, the system has the  potential to optimize engine operation across all RPM ranges, improving efficiency and overall  performance without requiring major changes to existing engine platforms.
