NGK REMINDS: UNNOTICED WASTE In modern vehicles with electronically-controlled, ignition and fuel injection systems, many of the symptoms of problems seen in the past are not recognizable today. For example, a vehicle may be in need of maintenance, but everything seems to be operating as normal. NGK reminds motorists to consider this, especially before taking highway trips that are longer than normal or during the summer months. Take this example: when the ignition system components are new or in good condition, the ignition coil produces enough voltage to supply current to produce spark in the spark plugs, with the ideal effect of total combustion. As components get older (spark plugs, cables, batteries, alternator, distributor cap), the ignition coil increases the supply of voltage to accommodate the deficiencies. This voltage increase has a limit, which is the maximum supply of the ignition coil. When that limit is exceeded, there will be ignition failures and a subsequent loss of power, increase in fuel consumption, and high emission of pollutants. To
avoid being surprised by these problems and an inconvenience during
a trip, in addition to the expense of emergency repairs, NGK recommends
that motorists find a trustworthy repair shop to inspect the engine's
electrical system. |
