While cars equipped with the new “breaker less Electronic Ignition Systems” will not normally change timing since there are no breaker points, the timing light can still be used to note changes in timing caused by troubles in the ignition system as well as for resetting timing when components are changed or he vehicle is tuned. In addition, normal wear on the breaker point‐rubbing block will have the same effect on the point gap or dwell angle. The instant of spark plug firing is determined by the opening of the distributor ignition breaker points and will change any time the point gap or dwell angle is changed. In most cases, these marks appear on the engine harmonic balancer attached to the crank pulley at the lower front of the engine. In order to allow setting and adjustment of the engine timing, special “Timing Marks” are provided on each engine during assembly. Engine timing is changed by adjustment of the ignition distributor. The spark occurs after the piston has started down in the cylinder (ATDC). On some late model cars equipped with various emission control devices, the timing is retarded so that Two additional terms that manufacturers use when describing timing are “Advanced” and “Retarded.” When the timing is advanced, the spark will occur before the piston reaches the top of the engine cylinder (BTDC). In order to completely burn the air/fuel mixture in the car’s engine cylinders, most timing is such that the spark occurs at a point several degreesīefore top dead center (for example, 4 BTDC) to assure that full power of the explosion is obtained. Timing is given in degrees Before Top Dead Center (BTDC) or After Top Dead Center (ATDC) in the manufacturer’s specifications. With the Xenon timing light, the car owner can reset the timing to the new car standards and regain lost power and increase mileage. Due to normal engine and ignition system wear, the timing can change and will reduce both power and mileage. This is “Timing.” Each engine manufacturer determines at the factory the exact timing necessary for various engines so that each ounce of power is obtained from every gallon of fuel. The precise instant of that explosion must be such that the maximum power is delivered to the engine piston. In order for an automobile engine to function, three things are necessary: air, fuel, and a spark to ignite the air/fuel mixture and create an explosion.
