IGNITION CONTROL DEVICE FOR INTERNAL COMBUSTION ENGINE

Title:

IGNITION CONTROL DEVICE FOR INTERNAL COMBUSTION ENGINE

Document Type and Number:

Japanese Patent JPH0763146

Kind Code:

A

Abstract:

PURPOSE: To execute ignition control based on a proper electrification time by preventing an error of the electrification time due to fluctuating steady see battery voltage.

CONSTITUTION: Since a data of estimated rise up time T11 is stored in a RAM in each cylinder and also storing a mean value of maximum/minimum values Y-MAX, Y-MIN in the past six ignition components of the rise up time T11 as the central value in the RAM, to read, prior to ignition control of each cylinder, the central value 0 of the cylinder from the RAM set as an electrification time Ton in the next time, ignition control can be executed, based on the electrification time Ton almost not containing an error due to fluctuating steady state voltage.
