This project aims to develop universal and programmable engine management systems for gasoline direct-injection engines with lean-burn technology and optional natural gas port-injection. The new engine management system will enable higher fuel efficiency than its predecessors and the increased use of nationally-produced natural gas. The project aims to overcome three main problems that limit efficiency improvement of direct-injection engines, namely: misfiring, unstable combustion, and soot emission. How these issues are impacted by additional natural gas port-injection will also be explored. This project aims to accomplish this by combining fundamental in-cylinder optical measurements and detailed modelling.
