  • Electrical Control Of Air Or Fuel Supplied To Internal-Combustion Engine (AREA)

Abstract

PURPOSE: To protect a fire owing to fuel leakage by immediately stop the operation of electromagnetic fuel pumps when the rotation of an engine stops in a system where a carburetor air fuel ratio is controlled near a theoretical air fuel ratio by detecting a component in exhaust gas.
