What is the benefit of wasted spark?
With a wasted spark, the crankshaft can be used instead, as the system fires on both upward strokes. It simplifies the mechanical arrangements since there is no distributor drive and the contact breaker cam can be fixed to the crankshaft.
What effect does an open spark plug wire have on waste spark ignition?
IGNITION COIL FAILURES If a spark plug or plug wire is open or has excessive resistance, the ignition coil’s output voltage can rise to the point where it burns through the coil’s internal insulation causing a short. The insulation in many coils can be damaged if output exceeds 35,000 volts.
How often does a coil fire on a waste spark ignition system?
Because the coil fires the spark plug on the exhaust stroke as well, it is appropriately named ‘wasted spark ignition’. In effect, the spark plugs fire simultaneously and twice as often. One of the two paired spark plugs is always negative polarity while the other spark plug is always positive polarity.
How does waste spark ignition work?
Each pair of coils would provide power to two spark plugs. Since one plug is fired on the exhaust stroke, serving no real purpose, the system was known as a “waste spark system.” This style of ignition has negative and positive polarity sides to the coil; meaning the spark plug also has positive or negative polarity.
What does a spark tester do?
A spark plug tester is a handy tool that allows you to check if your spark plug is working properly. It can also save you time by allowing you to check if the problem is actually in your ignition.
Why should a spark tester be used to check for spark rather than a standard spark plug?
A spark tester is used to check for spark in comparison to the standard spark plug due to the reasons given below: Without the spark tester the user may ok the ignition system since the normal spark plug may spark across a ground spark. So, the spark tester is more preferred.
What is another name for a waste spark ignition system?
Modern motorcycles are almost all single-fire bikes, but dual-fire ignitions (also known as “wasted-spark” systems) are interesting because they set the stage for single-fire ignitions as we know them today.
