HCCI Engine Modeling for Real-Time Implementation and Control Development

A propane-fueled homogeneous charge compression ignition (HCCI) engine model has been developed for the development of new engine control strategies in which a single-zone combustion mathematical model is adopted. The model has a reasonably simple structure and is implemented in a SIMULINK environment for simulation studies. The results of simulation studies show that the model can provide information on autoignition timing, engine work output, gas temperature, and concentrations of in-cylinder species. Model validation has been conducted by comparing the simulated output with experimental results obtained from a single-cylinder HCCI research engine. The comparison shows a fair agreement between the simulation and experimental results.

The Development of a Novel Microwave Generated Plasma Reactor for High Throughput Oxidation Processes

This paper describes the development of a microwave plasma reactor for the oxidation of gaseous organic contaminants in air. The reactor was designed such that plasma could be sustained at atmospheric pressure or greater with an effluent gas flow rate of up to 2000 l/min. The oxidation of methane was chosen as the test reaction for laboratory studies.
