How does a car timing light work?
When you pull the trigger of the timing light (with the engine running), each time the Number 1 plug fires, the timing light flashes a beam of light. The strobing timing light “freezes” the motion of the pulley and allows you to see how many degrees before or after TDC the spark is firing.
What is the meaning of timing in automobile?
Timing – it has a couple of different meanings when applied to your car’s engine. Ignition timing refers to when spark is created during the engine’s cycle. It needs to be just right or you end up losing power, increasing fuel consumption and producing more emissions in your exhaust.
How do you know if your timing is too advanced?
Pinging/Knocking This causes the fuel and air mixture to ignite and push back against a piston as it is still trying to compress the fuel and air mixture. Timing that is too far advanced will ignite the fuel and air mixture too soon and will cause pre-ignition.
How do you check timing without a timing light?
