Capacitor discharge ignition (CDI) or thyristor ignition is a type of automotive electronic ignition system which is widely used in outboard motors, motorcycles, lawn mowers, chainsaws, small engines, gas turbine-powered aircraft, and some cars.
Driving.co.uk ranked it #14 on their list of the 23 ugliest cars ever made, [136] Auto Express ranked it #5 on their list of the ten ugliest cars ever made, [137] and Drive.com.au included in their article on the worst cars of the 20th century, calling it "one of the silliest-looking cars of the century".
Failed aluminium electrolytic capacitors with open vents in the top of the can, and visible dried electrolyte residue (reddish-brown color) The capacitor plague was a problem related to a higher-than-expected failure rate of non-solid aluminium electrolytic capacitors between 1999 and 2007, especially those from some Taiwanese manufacturers, [1] [2] due to faulty electrolyte composition that ...
On March 31, GM announced it was going to recall over 1.5 million more cars of six different models, due to faulty power steering. Of these, over 1.3 million were in the United States, and three of the models were also involved in the faulty ignition recall. The total number of cars recalled during 2014 as of 1 April was 6.26 million. [6]
An alternative system used in automobiles is capacitor discharge ignition, primarily found now as aftermarket upgrade systems. [3] Electronic ignition was a common term for Kettering inductive ignition with the points (mechanical switch) replaced with an electronic switch such as a transistor.
Structurally, capacitors consist of electrodes separated by a dielectric, connecting leads, and housing; deterioration of any of these may cause parameter shifts or failure. Shorted failures and leakage due to increase of parallel parasitic resistance are the most common failure modes of capacitors, followed by open failures.
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.
Measuring ESR can be done by applying an alternating voltage at a frequency at which the capacitor's reactance is negligible, in a voltage divider configuration. It is easy to check ESR well enough for troubleshooting by using an improvised ESR meter comprising a simple square-wave generator and oscilloscope, or a sinewave generator of a few tens of kilohertz and an AC voltmeter, using a known ...
