Modeling Multi-Cylinder Intake Plenum Pressure in a Single-Cylinder Intake Plenum With Proportional and Poppet Valves Acting in Parallel

The main focus of this paper will be on the modeling of a simulated Intake Airflow Simulator (IAS), a patented device that can manipulate the gas dynamics of the intake plenum of an internal combustion engine, with the use of proportional and poppet pneumatic valves that operate in parallel with each other. The goal of the IAS, with regard to the Powertrain Control Research Laboratory (PCRL), is to simulate a multi-cylinder’s intake air gas dynamics on a single-cylinder research engine that is unique to the PCRL. This paper will include background of the technology developed in the PCRL, the methodology behind, current work, results obtained, conclusions inferred, and references used to model and control the simulated IAS [1].
