Abstract
PURPOSE: To uniformly distribute fuel to all the cylinders of an internal combustion engine by controllably responding fuel injection amount to the cylinders at time in delay corresponding to transportation from the intake stroke at each of the cylinders to thereby optimize the air/fuel ratio at every cylinder.
CONSTITUTION: Applied to an electronic control circuit 8 are a crank angle signal θ from a crank angle detector 7 attached to an engine 5, a revolving speed signal N oscillated at every ignition of the respective cylinders from an ignition signal generator 8, and an air amount signal Q from an air amount detector 2. The circuit 8 consists of a flip-flop 10, a variable resistor 11, gates 12AW12D, integrators 13A, 13B, transistors 14A, 14B and diodes 15A, 15B, etc. to produce a control signal Δt to control one or both of fuel injection time and starting time of a fuel injection valve 6 according to the parameters θ, N, Q in response to the time series of the suction strokes of the respective cylinders.
