Delphi Automotive PLC is an automotive parts manufacturing company headquartered in Gillingham, Kent, UK.[1] It is one of the world's largest automotive parts manufacturers and has approximately 161,000 employees. With offices worldwide, the company operates 126 wholly owned manufacturing sites, and 15 technical centers across 32 countries.This paper presents a theoretical and experimental study of a cylinder deactivation valvetrain system for the integration into an Engine Management System (EMS). A control-oriented lumped parameter model of the deactivation valvetrain system is developed and implemented using Matlab/Simulink, and validated by experimental data. Through simulation and experimental data analysis, the effect of operating conditions on the dynamic response is captured and characterized, over a wide range of operating conditions. The algorithm provides a basis for the calibration of the deactivation hardware. The generic characterization of the dynamic response can simplify the calibration parameters for the implementation in engine management systems.
