A Study of Optimum Engine Scheduling and Its Application to Fluidic Fuel Injection,

摘要

The report describes a method of determining the true optimum air-fuel requirements of a spark-ignition internal-combustion engine for use in a prescheduled fluidic fuel-injection system. This air-fuel information is usually taken in an incorrect manner. The data in this report are taken correctly and result in the true optimum operating schedules. It has been determined that the true optimum air-fuel ratios are about 10% leaner than that normally thought. A discussion of this fallacy is presented. The optimum ignition timing is also investigated. A fluidic fuel-injection system utilizing this air-fuel information is proposed. In this fuel-injection concept,the operator selects fuel consumption and the fluidic control circuit schedules and controls the air consumption. The advantages of this type of system are presented.
