Abstract
An electronic control system for an internal combustion engine. The system detects a property of the gasoline such as a vaporization characteristic by using refractive indexes. The system then detects various operating conditions of the engine. The system also determines various control amounts of the engine in accordance with the detected gasoline property and the various engine operating conditions. The system may determine a rate of fuel injection into the engine in accordance with the detected gasoline property. The system also controls the engine in accordance with the various control amount. Finally, the system detects that the engine is in an improper controlled state and may suppress one or more of the controls.
