Abstract
An electronic control fuel injection system for a spark ignition internal combustion engine is described which controls air flow rate as function of fuel flow rate by transmitting an operator's depression stroke of an accelerator pedal to a fuel selecting mechanism which determines the fuel flow rate, applying a signal representative of the selected fuel flow rate to a computer together with various correction information, calculating by the computer from the selected fuel flow rate and correction information, the optimum air flow rate, and determining the opening of a throttle valve from the calculated result via a throttle valve servo mechanism. The invention is particularly useful in eliminating hesitation of an automobile while attaining both fuel economy and low harmful exhaust emissions.
