Performance monitoring and acquisition system design of gasoline engines based on oxygen enriched combustion

In this paper, based on the status that in oxygen enriched combustion the dynamic performance of gasoline engines are remarkably promoted and the emission performance is also improved while NOx emission is seriously aggravated, the gasoline engine performance measurement and control system is built; the performance monitoring and acquisition system of oxygen enriched gasoline engines is designed, and its hardware structure and communication method are specified, the corresponding system software and the man-machine interface are developed to achieve the gasoline engine performance monitoring and acquisition; by controlling the flow rate of oxygen and carbon dioxide, the intake air components of the engine are adjusted to optimize the engine performance, save energy and reduce emissions.
