Show Electronic More Coming 75 Components that start out as add-on equipment by buffs sometimes end up as standard equipment on the family tie-but for different The electronic ignition systems that are standard equipment on many of today's au- will be standard on most of the 1975 models-are a good THESE units originally were installed by performance buffs because standard ignition components could not produce the strong spark required by competition engines which turn at much higher revolutions per While the performance requirements of your family car's engine differ from a racing-type electronic systems benefit everyone by providing increased gas longer intervals between tune-ups and lower exhaust CONVENTIONAL ignition systems utilize a mechanical switch-commonly called is activated by a rotating cam located inside the As the points open and a very high electrical current is produced by another component in the system-the functions like a This electrical jolt travels along the spark plug wire to the spark where it jumps a small air gap at the tip of the creating the spark that ignites the air-fuel mixture inside the The points are subject to mechanical wear and deterioration and must be adjusted and replaced otherwise the engine will run less efficiently or In addition to wasting engine misfire typically increases exhaust emissions MOST electronic ignition systems eliminate the points by substituting electronic switching Since these components do not the engine its for much longer These systems typically generate a more powerful and longer duration This allows for more complete burning of the air-fuel resulting in better economy and reduced The increased capacity of some electronic ignition systems also helps to fire fouled spark plugs and start flooded |
