METHOD OF LIMITING CURRENT CONSUMPTION IN GLOW TIME CONTROLLER, AND GLOW TIME CONTROLLER

摘要

PROBLEM TO BE SOLVED: To avoid damage to a glow time controller, in particular, damage to a field effect transistor that realizes polarity reversal protection.SOLUTION: The present invention provides a method of limiting the current consumption in a glow time controller in which a predetermined number of glow plugs are controlled with pulse-width modulated control signals derived from a battery voltage, and a method of reducing the number of simultaneously operated glow plugs in a glow time controller provided with a device limiting the current consumption.
