ENHANCED GLOW PLUG CONTROL

摘要

Methods for controlling a glow plug temperature in a diesel engine in response to one or more past operating conditions related to glow plug aging are described. Thereby, the glow plug life calculator of the present disclosure may be useful for indicating degradation of the glow plug in order to prolong the useful life while increasing glow plug durability. In one example, a first phase voltage is reduced in relation to an engine parameter associated with engine start time in order to allow the life of the glow plug to be prolonged while maintaining engine start time at an acceptable level.

主权项

1. A method for controlling voltage applied to a glow plug connected to a diesel engine, comprising:
indicating degradation of the glow plug in response to one or more past operating conditions relating to glow plug aging; and controlling the voltage applied to the glow plug in response to said indication to prolong the life of the glow plug.
