TIPS
Timing Light Basics
Automobile engines work by mixing
air, fuel and a spark to ignite the fuel/
air mixture, creating an explosion, that
powers the vehicle. Maximum power
from the explosion must be delivered to
the engine at a precise instant. Attaining
that precise instant is called “Timing”.
Timing is essential for fuel economy and
power. Automobile engine manufacturers
determine the exact timing necessary
for every engine they build. Normal
engine and ignition system wear causes
the timing to change, reducing both fuel
efciency and power.
