Abstract
Control of combustion by fuel injection is a basic part of the original concept of the diesel engine. The analysis presented shows how a digital computer engine with automatic compression ignition is used to investigate some of the many factors involved in the control of compression ignition and burning of fuels.
The digital engine, including an automatic digital combustion process and digitalized fuel characteristics, appears to be the only practical means to coordinate all the interrelated factors involved in the simple diesel engine with no ignition system. This digital engine materially aids in properly interpreting engine test data to show the correct steps for obtaining optimum engine development.
This paper presents the progress made on one contemporary digital engine in the field of automatic combustion by compression. The achievement of this automatic burning feature represents a vital step needed to allow the combustion process to react to the many interrelated factors, such as engine design, operating conditions, fuel physical properties, chemical fuel ignition delay characteristics, and the complex compression situation resulting from injecting fuel over a period of time which may include the burning period.
