Real-Time Steady-State Oil Consumption Measurement on Commercial SI-Engine

The oil consumption has been measured in real-time for steady-state operating conditions for an approximately 2 L SI-engine. These oil consumption measurements have been obtained for the engine stack (total) as well as for the individual engine cylinders with the current generation of Southwest Research Institute (SwRI) developed SO₂ analyzers. The 10 steady-state data presented in this paper is only a small fraction of the 234 steady-state data taken as part of this project. This paper is important since few complete data sets have been published in this area of research and since it illustrates the technical superiority of this analyzing tool for engine development purposes.
