Abstract
A motor vehicle engine (10) has glow plugs (20) for aiding combustion of fuel in combustion chambers of the engine when the engine is cold and an ignition switch (24) is operated to crank the engine. An aberration in engine speed (36) is used to indicate an under- or non-performing glow plug. Data from sources other than the engine speed source (28), such as data related to engine fueling, is also processed by a processor (30) to exclude them as the cause of the aberration.
