or there may be one or more bad spark plug wires. To diagnose this kind of problem, observe the firing pattern for each cylinder on an oscilloscope. A higher than normal firing voltage in any one cylinder may indicate excessive resistance in a plug wire, a loose plug wire, or a badly w...
In the mid-1980s, spark plug manufacturers started making plugs with copper core center electrodes. Copper is an excellent conductor of heat and allows plugs to run hotter without causing preignition. This improves fouling resistance, ignition reliability and plug life. It also reduces the number ...
The main parts of a spark plug are the insulator, the metal shell, and the two electrodes. The insulator is made of sintered aluminum oxide (Al2O3) and filler material, such as zirconia, in order to provide good heat conduction, mechanical strength, resistance to thermal shock, and anti-...
Resistorsresist the flow of electricity. You can use them to protect sensitive components like LEDs. The strength of a resistor (measured in ohms) is marked on the body of the resistor using small colored bands. Each color stands for a number, which you can look up using aresistor c...
Return to Diagnostic Chart Is a spark getting to the plugs? Some sickos just grab the boot of a plug and touch the engine block to see if they get a 20,000 Volt jolt, but that's no longer my idea of fun. I usually pull a spark plug wire, stick a screwdriver into the metal cl...
Photoresistors, orphotocells,are light-sensitive, variable resistors. As more light shines on the sensor’s head, the resistance between its two terminals decreases. They’re an easy-to-use component in projects that require ambient-light sensing. ...
resistance which they get simply through the sheer length of their insulator (it's a long way from the center electrode's tip back up to the metal shell). However, the two-stroke's incoming charge doesn't always do a good job of cooling its plug, and you have to be very cautious ...
