It uses 2 ignition coils and no ignition distributor. Cylinders are fired in pairs (dual fire) - 1 and 4 together, and 2 and 3 together. The crankshaft position sensor is sensing the movement of two radially opposed position plates on the flywheel, one of which is magnetized, and the other is not.
Four spark plug wires (distributor end on the right, spark plug end on the left) Spark plug wires (also called high tension leads) are electrical cables used by older internal combustion engines to transmit high-voltage electricity from the distributor to the spark plugs. Tension in this instance is a synonym for voltage. High tension may also ...
The contact breaker is operated by an engine-driven cam.On an engine with a distributor, the contact breaker can be found beneath the distributor cap.The position of the contact breaker is set so that it opens (and hence generates a spark) at exactly the optimum moment to ignite the fuel/air mixture.
The first mass-produced electric ignition was the Delco ignition system, which was introduced in the 1910 Cadillac Model 30. In 1921, Arthur Atwater Kent Sr invented the competing Unisparker ignition system. [2] By the 1980s and 1990s, distributors had been largely replaced by electronic ignition systems.
The key feature of Motronic 1.7 is the elimination of an ignition distributor, where instead each cylinder has its own electronically triggered ignition coil. Motronic 1.7 family has versions 1.7, 1.7.2, 1.7.3, all of them used on M42/M43 engines in BMW 3 Series (E36) up to 1998 [8] and BMW 5 Series (E34) up to 1995. [9]
The Duraspark II ignition system is a common upgrade [1] for older Ford cars equipped with a points-type ignition. In most cases, the distributor will interchange with the older-style points distributor. The system is similar to some aftermarket systems [2] and the control module may be easily swapped. Duraspark swaps are easy and can be run by ...
An "E" was added to the model of the vehicle (standing for "einspritzung", the German word for fuel injection). This engine is identified by TSZ ignition and multiple belts for the alternator, power steering and air conditioning compressor (where fitted). Cubic capacity: 1,997 cc (2.0 L). Power output: 90 kW (122 PS; 121 bhp) Application
As batteries became more common in cars (due to the increased usage of electric starter motors), magneto systems were replaced by systems using an induction coil.The 1886 Benz Patent-Motorwagen and the 1908 Ford Model T used a trembler coil ignition system, whereby the trembler interrupted the current through the coil and caused a rapid series of sparks during each firing.
