Why does my ignition light flicker at low speeds?
But the light does behave in slightly different ways depending on the type of generator fitted to your car. If your car is equipped with a dynamo it is normal for the light to flicker at idling speeds as this type of generator produces little or no current at low engine speeds. The light should extinguish when the engine speed is raised.
Why is ignition timing important in an engine?
by Don Bowman. Ignition timing refers to the point at which the spark plugs ignite the fuel within an engine’s cylinder. Proper timing is all-important to the thermo-efficiency of the engine. The first thing to keep in mind is that fuel burns at a certain rate in an engine regardless of the rpm.
What happens when fuel is ignited at the same 10 degree timing?
As the engine rpm increases to 3,000 rpm, the fuel, — still requiring the same time to burn — would never have sufficient time to burn if ignited at the same 10-degree timing. In order to have the same result, the fuel must be ignited much sooner in the compression stroke.
What causes a car to go back up after ignition?
The burning fuel expanding forces the piston downward. At this time the valves are closed. This is the power stroke. As the crankshaft turns, the piston begins to go back up and the camshaft opens the exhaust valve. The upward moving piston forces the burnt gases out of the cylinder.
Why do ignition points open at higher speeds?
At higher speeds, the points open before the current has time to reach this maximum value. In fact, at very high speeds, the current may not reach a value high enough to provide sufficient spark, and the engine will begin to miss. This current through the coil builds a magnetic field around the coil.
What can cause an ignition switch to fail?
(These generalizations, depend significantly on year, make, and model.) Worn ignition switch contacts, temperature problems, or broken springs can all cause the ignition switch to fail, preventing you from starting your car. On the road, poor ignition switch contacts could shut the engine off while driving, which could be dangerous.

Why is my car not turning on when I Turn on the ignition?
Of course, if you access the car itself with your key, you likely won’t be able to turn on the ignition because of all those extra tumblers. And on the off chance that you do turn the ignition cylinder, the immobilizer won’t allow you to start the car, because it’s protected by one-in-millions of transponder codes.
