Development of engine management systems for turbocharged gasoline direct-injection engines with optional natural gas port-injection

该项目旨在开发通用和可编程的发动机管理系统，用于汽油直喷发动机，采用稀燃技术和可选的天然气端口喷射。新的发动机管理系统将使燃油效率比其前身更高，并增加了对国内生产的天然气的使用。该项目旨在克服限制直喷发动机效率提高的三个主要问题，即：失火、燃烧不稳定和烟尘排放。此外，还将探讨额外的天然气注入对这些问题的影响。该项目旨在通过结合基本的圆柱体内光学测量和详细的建模来实现这一目标。

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.
