Abstract

Cylinder Deactivation System, CDS or generally referred to as variable displacement is a technology developed that can permit the total engine displacement to vary by shutting down one or more cylinders to increase overall fuel efficiency. The primary study of this research was to simulate how CDS would perform when applied to passenger vehicles by using MATLAB Simulink. Vehicle modelling using MATLAB Simulink is a process of creating a reference tool to the real world counterpart and using existing parameters to obtain results via simulation. The difficulty in this case study was formulating a functioning model for simulation purposes and determining the CDS performance under any number of working cylinders. Objectives of the research were formulating the vehicle longitudinal model, predicting CDS performance when applied to passenger vehicles, and proposing a control strategy for the CDS when used. The methods used were first deriving the necessary equations based on vehicle dynamics, creating the vehicle longitudinal model using the developed equations, and finally simulate it to get the theoretical results. The results gathered from this research were based on the output value of the model which was the vehicle speed.
